[Drakelist] TR-7 S meter issue
Hi, maybe someone on the list can help me troubleshoot this. My TR-7 is now working VG+ with with one exception. the S meter reads way high on receive. Wattmeter portion is correctly set per manual, and all other receive alignments are spot on per the manual. I've gone over the S-meter setup 3 times, and same result. An S-9 signal is 30 over, calibrate is about the same, 30 over. I've tried a separate signal generator at 50mv and its 30+ over (elecraft oscillator). Same 50mv signal gen used to check TR4C and its S-8, and TTec Omni VI is same. Any ideas as to where I should look first? Or, are any other alignment settings critical enough as to indirectly cause this problem?

The holy grail seems to be 50 uV for S-9 these days, although I have seen some radios over the years that were spec'd at 100 uV. The results I ended up with seemed to be a combination of circuit changes to the 2nd IF/Audio board and the adjustment method used. I've got my notes partly cleaned up, I'll see if I can finish it up this evening and get it up on the web.

Re: [Drakelist] Heil HM-10 Microphone.
Hello PSG, Correct regarding the impedance. Heil does offer, or used to, an impedance matching transformer to allow the Heil elements to be used on Drake/Collins rigs. They even sell a special cable for Drake-Collins. However, they do not work well. I have an HM10 and it barely has enough gain to use with my more modern SS TT Omni VI. So, when you use the transformer, to up the impedance, 1) it still isn't high enough to match up to the Drake tube rigs, and 2) not enough gain or output to run the rig properly. I suggest you sell the Heil, and look for a good Shure 444(d), D-104, Drake/Astatic 7075/7077, EV 664 or other good vintage high impedance microphone. The only other choice is to buy one of those microphone preamps like the W2IHY unit. It has a preamp and matching feature, I believe. Heil mics are good mics, but short on gain. Also, they work ok with an outboard or inboard microphone processor, used to up the gain. 73's David Wd9cmd - Original Message - From: John Stringer To: Philip Grocki ; Drakelist Sent: Wednesday, February 11, 2009 8:59 AM Subject: Re: [Drakelist] Heil HM-10 Microphone.

Re: [Drakelist] cooling fan noise
Carl, I just installed a 24v EBM-Pabst fan on the back of my TR7. Getting 12v out of the radio to run at about half speed. I then put a 2w 80 ohm resistor in series to slow the fan down more yet. This is the third try at fans, and its now nearly undetectable, but moves enough air OUT of the radio for adequate cooling. On my TR4C, I have a 12v fan with 4 of the little screw on drake feet like was used on the rear of radios to cushion and elevate the fan slightly above the top. I position it above the final cage.

Re: [Drakelist] TR-7 Alignment
Thanks to Gary and Jim, I think the finals in this rig are original, but not sure. I'll look closer next week and play with it some more. I had an ALC light on 28.7full brightness... at full CCW on the predriver with carrier control set at maximum CW. I may go back to 150w and have another go at it that way, but it seems like that should not make a difference? Other issues: I had tweeked the S-meter some, but still reads high. I've noticed at least 4 S-units higher than my Omni VI+ and about 5 S-units higher than my TR4C which I think reads a bit low. On Calibrate, CW, on the null, its 20-30 over. On the plus side, .the TR-7 receives great, had very good transmit audio reports, and A,B,C tests between the 3 radios are quite amazing. You'd thing the Omni VI+ would knock the old Drakes dead, but NOT SO. In fact, I cannot tell much difference between them. (except when using the Omni's DSP) If anyone has any ideas on the high S-meter reading, let me know, but until then, I'll do some more checking.

I ran into the 40 meter instability problem on two rigs in the 3000 serial number range, my own TR7 with 2sc2879 replacement finals and one that I picked up recently for resale with a completely stock PA. Both had the version 2 predriver. I found that the situation could be improved somewhat by increasing the low frequency negative feedback at Q2201, by reducing the value of R2203. It's possible that doing the same thing to Q2202/R2212 might help as well. Even with this mod, the second TR7 required a delicate balance between ALC setting and predriver gain setting to avoid 40 Meter oscillation with specified power out. I think I ended up with the predriver gain set just below maximum by a little ways. There appears to be a broad but definite gain peak in the 9.3 to 9.7 MHz area, and I believe this is responsible for the instability problem. I don't know what the root cause is at this point, and it does not seem to affect all units. 73 -Jim -- Ham Radio NU0C TR7/RV7/R7A/L7, TR6/RV6, T4XC/R4C/L4B, NCL2000, SB104A, R390A, GT550A/RV550A, HyGain 3750, IBM PS/2 - all vintage, all the time!

It does have the split rear panel, and the sn is 515x...can't confirm the last digit. 3. TR7A face plate, that looks original. 4. No idea of the proper boards, since no inside picture. 5.

There is a TR7A on ebay at present priced at $950 to start. So for lack of more information on boards included and the lack of the coverted TX jack, this is no doubt a converted TR7. At the end of production, Drake may have dumped some TR7 parts in Europe which included some TR7A front panels. This may account for the Holland ham's recollection of upgraded TR7's to TR7A's. In any event an upgraded TR7 to a TR7A was done by Drake, but never with a A front panel. This has been confirmed over and over again. What a supplier did in Europe, we have no idea.

[Drakelist] TR-7 Board History and head scratching
Hi to all, Looking for some historical information on Drake TR-7 boards. I have before me two DR-7 boards, one being green, and labeled C-3849 R. The second board is beige in color and looks to be a bit better quality. It is labeled C-3849 W. I also see that the circuitry is slightly different. Is the W a newer board? Next up, the power supply boards. Also have two before me, both green, one labeled B-3970 L and the other is B-3970 W. Again, the circuitry is slightly different. The later has a 0.05 ceramic cap bridgeing the center taps of the two onboard transistors. The L board has the same cap, but , its on the circuit board. Both have additional resistors on the bottom across R2129 and R2130. On the W board these appear to be 66 ohm each (if my eyes are seeing correct). The L board has resistors in the same position and these are 68 ohm resistors (ok, close). By the schematic, (and I have both the original 78 manual and the 80 revised editions), these two on board resistors should be 15 ohms. Checking both boards, (I did'nt pull the resistors to check their value), they are in fact marked 15 ohm and are carbon comp. Simple calculations net out just a shade over 12 ohms equivalent. I realize its not a big difference, but why was it done? Increase the current to the T-2101 Transformer? Which in turn would raise the voltage on the 25v line? So, the questions are, 1) Whats the history in the labeling, and 2) Are the bridging resistors on the underside of both power supply boards factory wiring? All this started because during an alignment, I could'nt get the required voltage on the VCO board, (shy by around 1-1.5v) and found I only had 22 volts going in instead of 24-25v.

I also was told the multi section can electrolytic on the radio is bad. Lots of dirt and dust but no corrosion. No idea if it needs more work besides cleaning, lubricating, and alignment. Who know what shape the finals are in. BUT, I had to have it. It was sitting on my local ham dealer's work bench for years. (Oh, I'm sure the blue dial lenses are washed out too). It has no noise blanker. I picked it up for a fair price if you figure the parts value. If you figure what I have to put into it, maybe $100 if I have no unexpected suprises without counting my labor, I figure I could maybe sell it working for around $50 under my actual parts cost. That is, if the finals still work and the filters are good. Otherwise it could swallow up another $200 to $250. What a deal. It had to be rescued. Was I wrong? Was I bad? Whats the matter with me?

Re: [Drakelist] TR-7 Frequency Problem
Terry, First check the TR7 power supply board for exactly +10v. This is the rightmost pot and you can measure the 10v next to it on the top of a resistor as I recall. Go to wb4hfn.com and you should find info on where to measure this. This is not the best place to measure and adjust, but easy for starters. The +10v pot is easy to bump and knock off. Certainly, ... don't touch it until you've measured the +10v. When it is off (more or less than +10v), this can effect most every circuit in the radio. Resetting to +10v might solve the problem in the short run, but any change to this setting usually requires a full alignment. The 10v is properly set by taking measurement on a trace on the motherboard. You'll need the service manual for this one. And a high quality DVM. While you are looking at the power supply board, look down about half way to the little transformer and make sure it is all in one piece. Sometimes the core comes loose and falls away. This makes for all kinds of stability problems, not to mention causing an unlock to the freq. display. If the +10v supply is spot on, I'd suggest a full alignment. Again, you'll need the service manual for that one. I'm sure others on this list have far more experience than I regarding a specific problem on 160, so I'll defer to their comments.

After warmup of a half hour or so, it would start working and and show 1870 Khz like it should. Now, it doesn't show 1870 khz at all and stays in the 17600-17800 range even after warm up.

When I switch to transmit the TR-7 readout shows 1870 Khz. When I go to RX then it goes back to 17600-17800 Khz. So where should I start looking in the TR-7 to find the problem?

Re: [Drakelist] Drake TR7 and R7
I'd say the rig was used for swl purposes, and the owner was trying to get maximum sensitivity out of it, although questionable how much more, if any.

The RIT on the R7 should be about plus or minus 3khz It has been modified to plus or minus 200hz. Yes 200hz. Why? Probably the same reason I reduced the range on the RIT control in my HR2510. WHen using the RIT as a fine tune control, you're not usually going more than a couple of hundred Hertz, at the most. There's really not much need for 6 KHz of range, and reducing the range makes it easier to fine tune with that tiny knob. 2. An SO239 has been installed on the back panel A. Connect the antenna to the SO239 so bypassing the Antenna Switch. B.Install a jumper between the SO239 and the spare RCA socket and put the antenna into its proper RCA connector so routing the antenna via the Antenna Switch--in other words the normal way. That's an interesting one. My fisrt thought is to allow the user to bypass the antenna selector, as the splitter has some loss through it. There is theoretical 3 dB dignal drop through any two-way splitter (half the signal goes to each port), plus circuit losses, which typically adds up to 3.5 to 4 dB in the real world. However, I was looking at the schematic just a couple of nights ago, and it appears that the splitter circuit is bypassed when the antenna selector is set to Main/Alt ... which would make sense. This would leave and small (probably insignifigant) loss in the cables and switch itself. In light of that, the only thing that really makes sense me is pehaps the owner wanted to use the antenna selector to feed two other radios other than the R7 from one of two antennas, at the same time the R7 was being used on a third antenna. Or maybe that it was an easy place to put a real antenna connector, and the owner elected to bypass what was essentially an unused feature when the radio was used in that configuration, or the isolation between ports wasn't sufficient for some reason. Maybe someone else has a more obscure reason? 73 -Jim NU0C ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
[Drakelist] L4B Troubleshooting Help
Hi all, Previously, I believe I discussed with some of you an L4B I recently acquired. To recap,..Looked good cosmetically, internals looked good with no visual burnt or dark areas and no signs of arcing. However, when fired up, I found that the plate current read around 2000v on low plate and 3000v on high plate (ssb). This seems way high to me (read on the rf unit meter). During this short time, the power supply got very warm. Also when switching from cw to ssb, the deck and supply made some noise (vibration or oscilation somewhere). At that point, I decided to rebuild the power supply as a first step to be sure I had the correct and clean b+. A fairly old unit by serial number, so I figured it was due before I went any further. Now we are all up to date. I just completed re-building the L4 supply with a kit from Harbach Electronics. The kit went well, and from start to finish, it took about 2 hours time. I tripple checked all the solder joints and connections. Having no 220 variac, and not wanting to convert both the deck and supply to 110 and back again, I chose to plug it in and see how it goes. At first all seemed fine. The amp was idleing with no rig or antenna connected. The power supply stayed way cooler than before and all seemed ok so far. Everything lit up, filaments lights, meters ect. However, I still saw around 1900v on the cw position (low plate). After a few minutes, I flipped the switch to high plate(ssb), heard a boing sound, saw 2900v on the meter, and a lot of noise and oscillation from the RF deck. I quickly pulled the plug. I could not tell for sure, but the most of the noise seemed to be coming from the rear of the rf deck near or from the transformer. I don't have any high voltage volt meters (past 1500v) so I can't check any contacts directly. Any suggestions on troubleshooting???.I don't think things are right !!

[Drakelist] TR7 Control Cable Plugs
Just a FYI to the list: After searching for the control cable cinch plug for my TR7, I finally located one at Electronic Plus. Tried the normal outlets such as Mouser, Digi-key, Allied, Newark and others. No stock on this obsolete plug. However, I did find it at Electronic Plus online. This outlet is in California and the plug was received yesterday. The plug is a female Cinch S-310-CCT and is normally on the control cable of the PS7. However if you run your TR7 on a non-Drake supply this plug comes in handy for user make up of ALC and relay cables for an external amplifier such as a L7 or L4 and others. If other sources are known, I would suggest posting to the list for anyone interested. Please note the web site as www.electronicplus.com versus another site as electronics plus.

[Drakelist] AC4R
To the List; I just completed the AC4R upgrade. The results were excellent. The board installed with little effort. I began this project due to my AC4 getting some age on it, and I had noticed a drop in output from my TR4C on 40m down to around 150-160w. My AC4 was purchased new by me at Dayton back in 79, so it was of the last produced, so I suggest anyone using the 4 line rigs to seriously consider this upgrade. My TR4C output is now back to 200w on 75 and 40, 180 on 20 and 160 on 15, which I think is typical of this unit with good finals. While it may be wishfull thinking,I think the radio sounds better as well. !!? The only comments I would make regarding the instructions are to cut each white wire to the bias pot individually to the shortest length possible. Otherwise, like me you'll be searching for some wire for the last connection from the new board to the pot. Also, on my supply, the can capacitor had a very large glob of solder on the ground which caused extra effort getting it out of there. If anyone has the same situation, you will need a hotter than normal iron or desoldering tool. I only have irons in the 20-30 watt range for most electronic work, and are inadequate to heat this solder. I was able to get it loose using two irons. 73's, David Wd9cmd___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

[Drakelist] L4 PS
Hello, Just acquired an L4B plus L4PS. First question: PS has a sn of 142X. This sn does not seem to match up to the ones on wb4hfn's site. Any history? The last Drake rig I ever saw with an X was a TR-6 prototype that I used back in the 70's. Second question: The caps in the power supply are blue sprague atoms with both leads on top of the cap and not axial. There also seems to be a skinny board at the base of these caps. I have'nt taken it apart to better understand the connections or modifications as yet. I'm assuming this is not original, since I understand Drake used axial capacitors. Am I correct here? And did Drake ever do any of the mod's outlined above? Looks like a pro job from looking at the tops of the capacitors and the little long skinny boards at the bottom? Before I picked this up, I had it in my head I'd need to get a upgrade board from the Heathkit Shop, but now I'm not sure that will be necessary, at least in the short run. Oh, I have'nt fired it up yet, so I cannot comment on the smell or anything else. I'm planning on bringing it up slowly on a variac. I was told it had been in storage for around 8 years.

Re: [drakelist] First Steps
David Chris Drake [EMAIL PROTECTED] made an utterance to the drakelist gang -- Hi Jason, and welcome back to the bands. Its difficult to tell where to start and I'm sure others out there will have separate opinions. I'd give it a try on 40 first. Without a dummy load, you'll have to look for a spot on the band that is inactive. Again, since this is the first time, set the resist, and reactance knobs mid way on the tuner. Then try to load up the t4x for max output or use the instructions in the manual. Once you get the t4 idling along, you can adjust the tuner for min. swr, or, as some do, maximum output on a wattmeter. Go back and forth until you are seeing the maximum output it will do. Best advise is to just give it a try, with very short tune up times, and tweaking as you go. You may have to go back and forth several times, so be patient until you get everything in resonance. Also, you'll not find much action like you were used to a few years back. The noise you are hearing is common. We are at or very near the absolute low for the sunspot cycle, and you have to be pretty dedicated to make contacts these days. Its likely your rigs are fine, and just a victim of the times. It will get better, hopefully soon. Its best to get a dummy load. Then you know you have a 50 ohm match, and then only have to worry about one thing at a time.

I have been an amateur radio operator for a number of years but mostly active on 2M. Never on HF... I bought a R-4B and T-4BX a number of years ago in hopes that I would start to explore HF more than just the random perhaps yearly scan through SWL. But then I joined the Navy, (Became an ET whose primary duty was the URT-23Ds on a ship, HF Transmitters ironically...) and put my Drakes pretty much into storage. Also, in this time became an inactive ham due to my command being in Japan and I had no place to operate. Well, I am back in the states, have my own place and pretty much the first thing I did was pull the Drakes out of storage, set them up on a cheap coffee table (I have no furniture now and am slowly buying more.. no desk!! gonna build one soon...) and attached a ~75' wire as an antenna through a MFJ-16010 Random Wire Tuner. And to save space because I have no room in an apartment that doesn't like things hanging out of their apartments (even on the 2nd floor) I spun the wire in a somewhat diamond shape using supports from a cardboard box that I cut up so the cardboard supports look like an X with an inward spiraling wire. Anywho, after that detailed setup, here is my situation. I can hear some stations just fine, I even got a SWL QSL card from the Canadian Time Standard station CAN. but I'm afraid to test TX, especially without a dummy load. A hamfest will be coming up in September in my area and I plan on getting one there unless I can get one that I bought that is in storage in Oklahoma sent to me. (Rargh, I digress again.) I would like to try to make this system back into full operation both TX and RX. I have no test equipment other than a pocket mulitmeter from Radio Shack and well, on very limited budget. I have seen comments here about replacing caps and such... how can one tell when that is needed exactly? I have so much RF noise in the area, I cannot tell if its just ambient noise or bad equipment... Working on this stuff is no where near as easy as working on the modular designs of the URT-23D and really without an o-scope.. I feel lost... I like to see signals... Any suggestions on how to test and if necessary replace components on this stuff would be greatly appreciated. I really want to learn my system inside and out and am willing to do everything it takes to get the Drakes 100%, budget willing...

Re: [drakelist] DMM recommendation
FYI to the group I too have a heath VTVM that I use frequently for receiver alignment and other uses. The probe is rarely included when you find one of the many versions (cosmetically) of pretty much the same design. The probe designed for these VTVM's is not necessary. The best thing to do is modify the input circuit, very simple to do. Then when the main switch is turned from AC to DC to Ohms, you have the correct input impedance and blocking. It makes the Heath as easy to use as the Simpson 260/270 series. You simply buy a set of standard probes and a stereo 1/4 phone plug and wire the two leads to it. I have the information here somewhere and can supply to anyone who wants. Its also available on the internet.

Re: [drakelist] DMM recommendation
Alan, most any Fluke will do as the others have said, and I have two bench top models to attest to that. The handhelds are all very good meters. The Fluke 117 is near the best of the affordable line, and the 110 is at the bottom. Of these the 115 or 117 would be a good choice. The 83's, 85's and 87's start to get pretty pricey, and you really pay up for the accuracy. An alternative to consider for less money is, believe it or not, a Sears Craftsman. You'll need to research the model numbers, but one of the two higher end models are very good meters with extra large numeral readout. I have the top model and keep it in my radio room in the drawer. Its a very handy meter, and accurate enough for most all I need to do. I got it off ebay, new in the package for $80.

[drakelist] TR7 2nd IF Audio board
Hi, Does anyone know about when, by serial number, Drake went to the newer version 2nd IF-Audio board? As much time has passed, I know that unless one is sure his/her radio is original, it may be hard to tell due to possible board changes before the current owner. But does someone out there has a good idea? FYI, my current TR7 is SN, 5392, split rear panel, late version NB, Late version pre-driver, early version digital control board and early version IF/Audio. I may be wrong, but the NB is likely a newer addition. I did notice that my IF/audio board has been repaired, an IC replaced and a poor soldering job that I had to clean up. I guess, bottom line, I'm trying to figure out if my audio board is original to the radio or not. Thanks, David WD9CMD

David Chris Drake [EMAIL PROTECTED] made an utterance to the drakelist gang -- Garey, Thanks for the link. My current TR7 has the first gen. board. Its mid 5900's, so your cutoff must be about right. I've 'heard' people say that the 2nd gen audio is much better, but you know what they say about perception versus reality. Perception is 90% of reality to many people. So when drake improved the specs, well, you know what I'm getting at.

Early 1980. According to Bill Frost, the 1496 was originally designed into the R-7, and was then adopted as a cost saving measure in the second generation TR-7. The IC replaced a hand wound toroid and a couple of alignment problems. It's pretty easy to spot in a TR-7, as it's right at the top right corner of the 2nd IF/AF board at the rear of the card cage. Version 1 has the toroid up there and a little U-shaped shield (yet another costly item not needed with the IC) while the Version 2 board has the IC and a few resistors. Personally, I doubt if you would notice the difference by ear. I have a couple of each, and can't say that I can hear the difference. Yeah, the 1496 has a wider dynamic range than the two diode PD, but the AGC kinda eliminates the advantage of wide dynamic range! I think it was purely cost saving, and a fancier set of specs couldn't hurt! :-) A dutch ham did a conversion by removing all the parts associated with the Version 1 and putting the 1496 on a small piece of perfboard mounted just above the original board. http://home.wanadoo.nl/cmulder/drake.htm#bookmark3 I'm sure we'll hear other opinions!! :-) 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line TR-4/C Service Supplement CDs www.k4oah.com David Chris Drake wrote: Hi all, Couple questions: Is there a significant performance difference between the first and second version 2nd IF/Audio boards?.

[drakelist] Parting out radios
Folks, it looks as though you can part out a TR7 and get more money for the parts (looks like almost double) than if you simply fixed the radio and sold it. (I'm talking about the various parts for sale on epay.) But I must also say the prices seem to be going up for ANY TR7, working or not. AND, the accessories are almost out of sight. (in my opinion) I suppose its basic supply and demand. For me, I'm emotionally attached to mine! PS, could'nt hear any of the Ohio guys this afternoon on the net. Been that way for several weeks now. We should be getting close to the upside of the cycle and we will all be having a lot more fun with radios. Oh.Hope everyone had fun at Dayton. David wd9cmd

Re: [drakelist] Low-pass filter etc. setup.
Hi, I have a W4 and use it after my mn2000. That way I can monitor the final matched output, as well as swr at the same time. Works out pretty good. Also, I have the peak reading board in my W4 so I can see SSB peak output. Makes it good to set the mic gain as well. So, what I have is TR4C, then MN2000, then W4, then LP filter, then antenna.

Re: [drakelist] Dumbish Question
Hi, most importantly the receiver, R4C, had the provisions for additional filter options both AM, SSB and CW. The TR4C later came out with the TR4CW which had a narrow CW filter built in. This transeiver was mainly a SSB unit until then. Another plus of the R4C was variable pass band tuning (PSB) as well as a notch filter. Neither of these were in the TR4C or any later versions. Both the R4C and TR4C had fairly hot receivers. Many hold that the R4C did not reach its potential until it was filtered up, had the optional noise blanker installed, and had the later sherwood mods performed. Most active hams prefer the R4B (B'line) where the package is pretty well complete. The R4C's are, however, newer units and did not have the copper plated chassis. Many hams today believe the R4C with sherwood mods is still competitive with ANY modern receiver/transciever. See the sherwood site for more information Output differed from the two units. The T4xc had two output tubes for nominally 120w output. The Tr4c had three output tubes for nominally 180w output on the lower bands. Add to this the comments from K9SQG and you pretty well have it. Also, simply google up Drake radios and you'll find a wealth of information.

Re: [drakelist] TR7 Project/Pwr Supplly Transformer
Thanks! The moral to the story here is this. Problem/Issue/Symptom: Radio is low or no output, syntheseizer will only settle down and lock up on two bands, and only after prolonged warmup. Start TS at powersupply. 10v oka bit high at 10.4v. Upon close visual inspection, found power supply transformer core top in two pieces on bottom of rig. Started pulling boards. DR7 first, then power supply board. Glued two top pieces together with super glue, then super glued the finished top piece to the bottom piece on each side. VERY light application of super glue with a toothpick. Also used a toothpick to shim up the bottom piece to make contact while glue set. Now, no need for Drake hookup wire to hold top piece on/in transformer. Top and bottom transformer cores now are together instead of separated. Reassemble and test. Rig now works on receive properly on all bands, but needs alignment. Adjustment of 10v and PBT controls completed, receive is comparable to my Omni VI+ on all bands. Further alignment will be needed since 10v is reset. Note here, its tough to pull this board and work with it without bumping the 10v pot, or the others as well. So any work on this area will likely require a complete re-alignment of the radio. Hopefully not a serious one, however. Note 2: Seems as though the operation of the transformer is not real critical, since super glue acts as an insulator. Plenty of flux lines remain around the core for operation. Note 3: Broke the rule: The only part of this TS that might be in error, is that I pulled boards and cleaned contacts prior to testing (I figured that I had the DR7 out, so might as well pull boards and deoxit contacts while I'm at it). So I did more than one thing before testing. I broke the rule here, but am reasonably sure the transformer issue was the sole cause of the synth lock problem. Other: Low output may be another issue to deal with. I'll be on that one, as well as alignment, this weekend. I may have need of a better signal generator if I cannot improvise, but we'll see. Need to figure a way to measure and finely adjust output. Well, gotta get an old Hammarlund and Swan off my bench (repaired) Sat AM first thing!! Ah...the joy of tubes. One whale of a lot easier for me to deal with!! Yep, sure is fun to resurect these old rigs. Hope this info is a benefit to someone.

At first I figured I'd need a new transformer. However, based on expert guidance from Ron and Bill, I was able to super glue back the two broken top pieces and then simply glued the top and bottom halves of the transformer together (my idea). I did leave the original Drake wire tie for originallity, but it no longer serves any funtion. That fixed the problem. The rig locks up on all bands just the way it should and suprisingly its on freqency with only minor adjustment. All functions seem to be working as they should on recieve. I'll be checking transmit tomorrow. I know I bumped the 10v pot in process, but seems to be ok. After checking xmit, I'll attempt full alignment and see where I end up. I did repaint the top lid, as it was a later Drake black replacement and was scratched up. I must say it looks very nice. Split rear panel, 5392, fully loaded.

Many of us have valuable experiences that, taken as a whole, represent what might be considered as how the experts fault isolate. One of the key elements in fault isolation is knowing the probabilities of various failures from the symptoms. For example, the service manuals don't tell you, for a given symptom(s), what the first most likely cause is, what the second most likely cause is, and so forth. The expert service technician knows this based upon experience, you know, that element that makes one over qualified and thus unable to perform (not sure I understand that concept but the job interviewers do). Such an undertaking can be quite large and would be the labor of love. I encourage the pursuit of such an endeavor. Along with the above, of interest might be tips and tricks, those things the experts use to make the job easier. For example, I have a process that I use when rebuilding/upgrading power supplies for the L4B/L7 linears. Having the parts on hand and a workable process speeds things up and keeps costs down.

Re: [drakelist] Microphone question
David Chris Drake [EMAIL PROTECTED] made an utterance to the drakelist gang -- Rich, Forget the mic for the time being. Do this first: Most of the three tube TR's with fresh finals will/should show between 180 and 200 watts out on 40m. Tune it up this way: ..Set the mic gain at 10:00. Set mode to the x-cw position and, watching the wattmeter (any will do), adjust the load and tune for maximum output, as well as the RF tune control (peak all three). Don't leave the rig in x-cw for more than a few seconds at a time. Again, using the wattmeter only, peak all three controls by placing the rig in the x-CW mode. This is the lock down/key down tune up position. Once you have peaked the rig here, key the mike and speak into the microphone in a normal voice and adjust the mic gain up or down from the 10:00 position previously set, until you see a small amount of movement upscale on the rigs meter. This should be about right for SSB work. It aslo means that the agc is in engaged. As an example, a D-104 or a Shure 444d, both high impedance mics, will be at the correct setting at about 10:00 +/-. A low impedance mic just won't work. Most any of the shure mics will work fine with a drake if they are high impedance. The rig does like impedances of upwards of 50k ohms, but generally, anything above 10k or so should work, just not sound as well as the others. Some of the Shure hand mics also work very good. I believe one was the 404?. But in the day of mobil operation with these jewels, that was the mic of choice. Another check to make, if the chosen mic does'nt seem to provide output on a peak reading meter, put the rig is x-cw and move the mic gain back and then advance it. At the point where no further ouput is seen, you are set about right. Normally, you want the gain control back just a tad for SSB to avoid overdriveing the audio. The AGC circuit should be in control, but with older rigs, it may not be up to par, so for best operation look at your rigs meter and adjust as previously stated. Once you have the rig tuned to max output as above and set the mic gain as indicated, you should see the output suggested above. If not you have another problem. If output is ok, move on to solve the mic question. Remember, if you have a rig problem, no mic is going to work right. So check the rig first.

At the best linear efficiency you could expect ~60% output on the radio, or 180 watts peak. I know there are those who say they get way more then that reading, but they are either running into an uncalibrated meter, or are putting more the 300 watts into to the rig. And I can see the hate mail coming on this :-) I would do the following: 1) you know you have an improper mic impedence, get that fixed. 2) see how many watts are coming out in CW mode. #2 will get you and idea how good your RF chain is in the TX. I would expect about 150 watts OUTPUT on CW. That should be easy to measure, but don't leave the rig in CW mode key down too long. The sweep tube finals are not made for key down duty. Seems to me that the TR3 did not need a key in the jack to be key down aka the key jack is closed by default. Was easy way to tune the rig as I recall. #1 will get good audio into the radio. Then see what your peak reading watt meter says. BTW, do both the CW and the SSB on peak reading mode of the meter. Peak reading modes are basically a hang amplifier. Charge a cap and use its voltage to driver the meter via a set of internal amps. The peak on CW, is *basically* what you would expect to see on peak of SSB if your meter is working correctly. Also, for CW on peak, you should see you meter go up quickly on keying the rig, and then slowly go back to 0 when you let off the CW carrier. If it does not, then your peak meter is not working as I would expect it to. 73, Ron WD8SBB On Sun, 20 Jan 2008, Rich Carter wrote: Rich Carter [EMAIL PROTECTED] made an utterance to the drakelist gang -- Ron I'm using a Daiwa HF wattmeter on the peak setting.

Re: [drakelist] MS-4 location
David Chris Drake [EMAIL PROTECTED] made an utterance to the drakelist gang -- A muffin fan on top, works so much better, you should really try to figure out how to keep the rig to the side of the supply/speaker. I use the rubber feet that you normally use to elevate the rig...the kind with the little bolt in them. These work great, or, you can use stick on feet. Then, on the top fan holes, fabricate a metal angle to either attach to one hole or bridge two. Paint black and attache to the fan near the contact side. Drill a hole for a mini switch and then attach the lead from a surplus wall wart of the proper voltage or even say 9 volts works well. Try a couple different ones to see which makes the fan blow quiet and efficient. Plug it in and there you go. Now you can switch it on or off as you need. If you'd like a pic, let me know. I've done then a couple different ways. I've found that to work the best, you position the fan in about the middle rear of the top, so that it pulls up and out over the pa cage and also pulls air from the rest of the rig. A better approach is to use two fans for a super cool TR4, but I find one works fine.

Garey hit it on the head when he spoke about the illusion of fan exit air not being as much as exit air: It is just that the exit air is directed into a smaller cross-sectional area. If you are just trying to enhance the existing convective air flow a little bit, then placing a fan over the top is easy and best. For example, I use a 12V muffin fan on reduced voltage sitting over the right rear corner of the R4-B on little fubber feet. That corner is where the power transformer and output tube sits so the heat buildup is greatest there. You can't even hear it run yet the R4-B runs considerable cooler. But if you're specifically trying to cool down a set of finals (vs just enhance existing convection) and are willing to run the fan at full voltage, then sticking the fan on the rear of the cage (where the obstructions are fewer) makes more sense. A fan at full voltage near the tubes is going to draw the heat out effectively whether it's allow to do so vertically or horizontally. Your rig is going to thank you for this. A commonly used acceleration factor in the electronics industry is a halving of circuit life for every 10 deg C rise. That's a real rough number but it gives you an idea of the importanance of good thermal management.

RE: [drakelist] MS8 Speaker
David Chris Drake [EMAIL PROTECTED] made an utterance to the drakelist gang -- Jim, I think Evan hit the nail on the head in a previous post. Why Drake did what they did with the MS7 and MS8, I don't know. I too have some hearing difficulties, and wear hearing aids. I will tell you that the MS 4, being bigger and in a bigger box, does sound way better than either of the aforementioned speakers. Another thing I have experienced is with the RV4C speaker. Not sure why, but it sounds excellent. I use it exclusively with my TR4C. I've not researched it, but there must be something about the speaker manufacture that tells the story. All I can say, is...my TR4C is only hooked up to the RV4C speaker, and the TR7A is hooked up to a MS4. Both sound great, with or without hearing aids inserted ! Maybe some experimentation with replacement speakers as Evan suggested, as well as some foam, or even enclosing the back would improve things, so for completeness, if you want an MS8, find one at a good price and do some tinkering. That's what us hams do you know !!

May I ask you this question please. In your opinion why would the MS-8 be an inferior sounding speaker ? Would it be because of the case it is in ? The area that the sound is being squeezed down into. I think the MS-4 has a 4 speaker but a larger cabinet and maybe that is why it sounds better. Also the R8 is fairly scarce and I think the MS-8 would look great setting next to my R8. I have four Drake rigs, the R-4A, T-4X.R-4C, T-4XC, and two TR-4C's and all the rigs have their own speakers, also the MN-2000 and a MN-4. I thought I would be really complete if I had the MS-8.

[drakelist] Passband adjust on tr7
Hi, have a tr7 that works great, except I've noticed when switching from Lsb to Usb, there is quite a bit of difference in the sound (PBT is off). Had this issue with alignment on a R2000 before and the fix is to adjust the balance trimmer until you hear the same pitch. If I switch in the PBT control and adjust, I can set it just fine, but it is not balanced. Whats the fix for this? I do have the service manual, but I was not clear if I needed to do a full alignment or not. I hesitate to go completely through it, since it works fine, and, as good or better receive than my new radios. Thanks, David Wd9cmd

I have to say, I never found any of them to be of much use, if any. Most of these are/were designed for pulse type noises, which, depending on your location and application may or may not be needed. These blankers usually sell for a lot of money or Epay, and seem to be coveted items to many. Practically speaking.Are they worth it?
