[Drakelist] Article in April 2009 QST
Hello, Did anyone read the article on modernizing a TR-7 by DK4DDS. It has information on adding a ton of features, such as DSP Noise reduction, curing the PTO Drift, Notch Filter, Improving the sensevity on the higher bands, Speech Processor and a bunch of others. It is some great food for thought, for bringing a great radio into the 21st Century. Great Stuff. I'm thinking very hard about trying most of them out. Most of them do not require modifing the original Circuit boards, just adding boards. If anybody had some comments/information on these mods, I sure would be interested.

Re: [drakelist] R-4B alignment question
"DW Holtman" <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- Agree, Thank you for the information. It makes perfect sense, since there is only 5 crystal slots, not counting the accessory slots. This receiver came out of a TR-44B and mates to a T-4B that comes with a built in speaker, but no PTO. Kind of interesting. I like the way they stack together, and the "door" to add accessory crystals. However, I think I think I would rather have a Transmitter with a PTO. Might get one soon, and put it in the cabinet. I was struggling with the transmitter power out, then discovered that there was no injection voltage out of the Receiver. There is a strong injection signal to the cathode of V2, so there is not much left between the cathode of V2 and the RCA connector. Thought I would do a complete alignment and get the receiver working well before going on to the transmitter. Thank you again for your as usual great information.

Before I put him on my list of people that I don't sell to, he bought a KWM-2 parts radio from me that was a stripped out parts chassis. I listed it as the PTO was not working. He stripped it apart more selling individual parts and listed the PTO as working well. This is impossible, the coil on the top of the case was torn apart. I would bet money the TR-7 he is selling as parts did not work and who ever gets the bad parts will have problems. If he buys a nice radio, the person who buys it, will get a nice radio.

How does it do this? Dosen't increasing the audio cause splatter? Why didn't the original manufactures use the most optimal audio modulation? To expand on what Evan said, the SP75 is a true RF speech processor that offers clipping as well as compression. It does this by converting the audio to double-sideband RF, processing and filtering it, and converting it back to audio. If you do some Googleing, you will probably find some good information on RF speech processing as the most effective type of processing. It does not increase splatter because of the built-in filtering (as long as you don't overdrive the radio, that is). It also has a noise gate circuit on the input to help keep unwanted background noise from being processed. On the practical side, I've used my SP75 with my TR7 at the LARC Field Day the past two years and gotten rave audio reports. The clipping action allows me to keep the audio peaks just below the ALC threshold (further reducing the possibility of splatter) while maintaining good average output. I'm sure an on-air demo could be arranged for you to actually hear one, since many list members use them. Fix it. Or sell it to me cheap, I'll fix it and use it... :) 73 -Jim -- Ham Radio NU0C TR7/RV7, TR6/RV6, T4XC/R4C, L4B, NCL2000, SB104A, R390A, GT550A/RV550A, HyGain 3750, IBM PS/2 - all vintage, all the time!

Re: [drakelist] RE: PM - lytics"
DW Holtman <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- Hello, I know that this is an old argument, but I would like to put my $0.02 in. I use a AN/PSM-2A meter to check paper caps. By cranking the handle, which is hooked to a generator, it applies around 500 volts to the cap under test, and displays the resistance in Mega-ohms. Many radios that I have worked on, virtually all of the paper caps have had a low resistance. A new/good cap will read in excess of 50 million ohms (mica's read infinity), bad caps read from zero to 10 million ohms or so. As a result a normal ohm meter will not really work for testing paper caps. I feel that the cost of new orange drops or metal film tubular (which I prefer because they have the same basic shape, and fit into the original location better) are very good insurance. You can replace a lot of caps for the cost of trying to locate an IF transformer or RF coils on a 50 year old radio. If original appearance is a concern (as it should be). Many types of paper caps can be heated and the insides removed. A tubular metal film can be inserted in the paper shell and sealed on the ends with hot glue and it is an excellent cosmetic replacement for the original. I have seen many paper caps, most recently on a Collins KWM-2 that the cap was so dried out it rattled after I removed it. I know that this is a personal decision, and many people with years on vintage gear prefer to leave them in, until they die. I say WHY? For a fraction of the cost of the radio, it is some pretty cheap insurance. Just me $0.02 worth. 73's DW Holtman GAREY - K4OAH wrote: GAREY - K4OAH <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- -Original Message- From: Laird Tom N <[EMAIL PROTECTED]> Sent: Apr 7, 2006 3:21 PM To: [EMAIL PROTECTED], w6ids <[EMAIL PROTECTED]> Cc: drakelist@www.zerobeat.net Subject: RE: PM - lytics" I agree with Gary's post, but I have been less fortunate with Electrolytics over the years.

I typically leave them alone except if I hear "hum" or they become warm to the touch. Both my R-390A's cans also needed changing. 73, Tom Laird W9QI Moline, IL. - My experience in 40+ years of working on Drake 4 Line gear is that the "paper" capacitors are very reliable, and do not require routine replacement. I can only recall replacing ONE, and it was physically damaged by someone "fixing" the receiver at some earlier time. On the other hand, by this time most of the electrolytic caps are suspect. Many are still working fine, probably low use units that have been stored in reasonable climatic conditions, i.e., not excessively hot or cold, dry or wet. An ESR meter can be used to determine with a degree of confidence their current condition, or they can just be replaced en masse. The bias supply electrolytic is easy, the Twist-Lok (can) types are a little tougher. Some "restuff" the can, as described at <http://www.thecompendium.net/radio/filtercap.htm> Others make substitutes such as <http://www.wa9tgt.com/Drake_R4A_Filter_Cap.html> Tom - That's what you get for buying that "off brand" gear!! :-) 73, Garey - K4OAH Atlanta -- Submissions:drakelist@www.zerobeat.net Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net -- -- Submissions:drakelist@www.zerobeat.net Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --
Re: [drakelist] Current limiting startup for Vintage gear
DW Holtman <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- Hello, The devices used for current limiting are are cheap, and easy to install. The link below is the data sheet for one brand. Note the CL-80 and CL-90, both work great on most receivers. In addition to providing surge protection on start up, the hot resistance is several ohms. This will drop the line voltage applied to the equipment a couple of volts, which is more the voltage that they were designed for. http://www.thermometrics.com/assets/images/cl.pdf The link below is from Jan Skirrow's site. It explains this type of thermistor, along with showing how they are installed in a R-390a. The installation for any receiver or transmitter will be similar. Just pay attention to what he says about heat generation. A good way to mount them is in an external 2 plug electrical box. They can be bought very cheap at Home Depot etc. http://skirrow.org/Boatanchors/TechTalk3.pdf I have about 20 CL-80's and 20 CL-90's, if anyone wants one, I will sell them for $3.00 each shipped. That is about what I will have into them with shipping. I also make some very nice complete units with RFI filters built in. They greatly reduce computer and other noises getting into your radios. If you would like more information, let me know. I can send pictures/specs of the units that I make. Hope this helps on the thermistor questions. 73's DW Holtman WB7SSN [EMAIL PROTECTED] wrote: [EMAIL PROTECTED] made an utterance to the drakelist gang -- On Thu, 19 Jan 2006, Keith Hamilton wrote: Has anyone tried the soft-start current limiting boxes sold by Sigtomics (http://sigtomics.com)?

[drakelist] R-4B alignment questions
DW Holtman <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- Hello, to the Drake group, I have a couple of questuions, that I hope someone can help me with. I'm in the process of doing an alignment, trying to use the procedure in the manual. Before attempting the alignment, replaced the electrolytic and paper caps, cleaned all switches, tube sockets and checked the tubes. It received, but not too hot. Now, for the rest of the story. The Cal procedure starts off with the Cal oscillator, it aligned great. Next it says to jumper off the cal oscillator circuit board to align the 50 KHZ BFO? I used 50 khz from my sig gan to zero beat the BFO to 50 KHZ, it worked great. Next to the 50KHZ If alignment. It says to hook the sig gen to pin 7 of V3 (2nd mixer) and adjust the sign gen for a zero beat at 5.645 MHZ. Next adjust the signal gen to give a reading of S-9. That takes a lot of power to get the S-meter up to a S-9 on pin 7 of V-3, is the If going into saturation?. I lowered the power a little(mayb4e S-6 or S-7) and T-10 adjusted , but T-7 would not adjust. Next on step 6.44, the crystal filter and filter match transformer At step 3, to peak it on the S-Meter, the point the frequency is peaked on the S-Meter, it is also zero beat, with no audio output.But, the instructions, say there should be a "High pitched audio tone". (It peaks at 5.645 MHZ the correct IF) I'm assuming that this procedure is correct, and really do not want to go any further, until I get things to work up to this point. Any help or suggestions, would be great. 73's DW holtman WB7SSN -- Submissions:drakelist@www.zerobeat.net Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --

[drakelist] T-4XB Question
DW Holtman <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- Thanks for all of the great help that I received from this fine group. I swapped out the 6HS6 with a 6AU6 and it now puts out around 100 watts on 40 meters. I'm going to do more cleaning, loosen and re-tighten the hundred or so small sheet metal screws that hold overything together on the chassis, to help make sure that everything is properly grounded. An alignment and I should be on the air. 73's DW Holtman WB7SSN Hi DW, If you have a good 6AU6 you can use this as a substitute for testing your rig. The 6AU6 has the same base pinout but slightly less potential gain than the 6HS6 so your output power may be somewhat less but should be close to normal. You can also test your 6HS6 using 6AU6 settings on your TC2. If you suspect the 6HS6 as being bad, look closely for either an open heater or inter-element shorts as otherwise it should at least produce some output in your T-4XB. If the tube is good, check related components in this stage. Good luck and 73, Rodger WQ9E -- Submissions:drakelist@www.zerobeat.net Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --
[drakelist] T-4XB Question
DW Holtman <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- Hello again, Thank to all who E-Mailed with help for my errant T-4XB. When I asked the question about the cathode of V-3 (Pin-7), I was not smart enough to read instructions. After putting the rig in tune mode (as stated in the chart for voltage measurements) the voltage read fine. The problem still persisted. Next, I warmed up my trusty URM-25 and first injected a signal on the plate of V-3, Pin-5 and adjusted the tuning/loading knobs for around 50 Watts. Great start! With a little bit of drive, got power out. The driver and finals are probably good, or at least usable. I next went to V-8, the Pre-Mixer. Injected the correct signal on the plate (Pin-5) and again had around 50 watts out. I looked at pins 1 (xtal osc input) and Pin-7 (VFO input) with an O-scope and both had a clean signal that changed with the band switch or tuning knob for the VFO. I next injected the correct frequency signal on both pins 1 and 7, with no output. I think that V-8 is bad. With a signal applied to the output of V-8, power out. Both input signals look good. All voltages look good. My Tube Tester a Heath TC-2 does not have data for testing this tube a 6HS6. I think that V-8 is bad. any ideas or suggestions to the contrary would be welcome. I'm going to order one tomorrow and check it out again in a couple of days when the tube arrives. Thank you again for all of the help. 73's DW Holtman WB7SSN Hello, I'm working on a T-4XB which has no output. The Power Supply had some ripple of the 250 Volt output, so I rebuilt the Power Supply. Replaced all of the lytics. Replaced the diodes with heaver duty 1N4007's. Replaced the 2 conductor cord with a three conductur grounded cord. Replaced the .01 noise caps with X1/Y2 discs and changed out the 1 watt bleeders with 2 watt resistors. On the transmitter, I tested all tubes, changed out the only 2 paper caps thqat I could find, and cleaned all switches, tube sockets etc. Now there is still no output. Measuring voltages, I found that the cathode of Tube V-3 on Pin-7 has 143 Volts DC on it. I know it cannot work with more than a couple of volts on the cathode. Any ideas/suggestions?

Perhaps expand it to the 2 line or even Hallicrafters gear. 73's DW Holtman WB7SSN - Original Message - From: "Dan Cotsirilos" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; Sent: Thursday, March 10, 2005 6:58 PM Subject: Re: [drakelist] FS-4 "Dan Cotsirilos" <[EMAIL PROTECTED]> made an utterence to the drakelist gang -- First of all "hosing" was a typo I meant "housing". 12 volts would also be needed also. Second 3 LED's was a brief description of the device. The item will be clean. It is being designed by a ex-Collins RF engineer who can build communications receivers from scratch so all worries of poor design are not necessary. These will be available for both the 4 line and the SPR-4. It will consist of 2 up down buttons that change in 500 khz steps. So I would like to know what kind of interest this group would have in a correctly designed unit?

[drakelist] Drake 2B front panel removal
Hello, I'm in the middle of removing the front panel from a Drake 2B. Everything is off except the Pass band selector switch (the pointer for .5, 2.1 and 3.6 khZ). I cannot see anyway to remove it to remove the pointer short of the completely disassembling the passband assemby. That is something that I don't want to do. Has anyone removed the front panel before? Thank you in advance.

Re: [drakelist] Why the big delay posting emails?
In outlook Express, click "Reply All". Go into the "TO" bar under "FROM" and delete everything but Drakelist@ etc. It should only send to the Drake list and not yourself..

[drakelist] Drake Power supplies
Hello, I have a quick question, that has probable been answered many times before on this forum. What are the differences between the AC-3 and the AC-4 power supplies? Will they both work on the TR-4 series and the T-4 series of radios? Thank you for your time. 73's DW Holtman WB7SSN
[drakelist] Question about Drake TR-4's
Hello, I'm new to the Drake forum and have a couple of questions that I hope that someone can answer. What is the major differences between the various TR-4 versions. IE TR-4, TR-4C etc. For general operating , it the C-Line (R-4, T-04) radios better perfomers than the TR-4 transcivers? I enjoy operating, but do not spend enough time on the air. I spend about half of the time on CW and half on SSB. I'm debating on what kind of rig to get. Any advice in this direction would be very helpful. I spend a lot of my spare time, restoring old boat-anchors, mostly Hallicrafters receivers such as the SX-100, SX-25 Etc Would also consider a swap of a good original Drake for maybe a nice SX-25 or possibly an SX-101. I would like to do the service including recapping my-self, so would like to get a rig that is original.. Thank you in advance for any informartion you have to offer. Best, DW Holtman WB7SSN
