Re: [Drakelist] TR-7 Question
I think a foolproof way to identify a real TR7A is to look at the cable from the mic input to the spare phono plug at the back.When this is done at the factory this cable is well and truly embedded in the wiring harness and is certainly not a last minute add on.

Unfortunately Drake, when they were liquidating their inventory, sold to anyone that wanted them, the top front panel section which indicated the TR-7A. I have personally seen those panels placed on very early TR7's with serial numbers in the 1000 range and we know the TR7A appeared around serial number 10,600. So in some cases purchasing a TR7A is a buyer beware. I wrote an article on how to identify the model differences for that very reason. Drake did in fact put the serial number in two places, on the rear panel and on the inside, front side of the front sub panel. It is major surgery to get to that area which is why most folks would not attempt. But to prove a point, it is one of several way to identify the exact model.

[Drakelist] TR7 with Modern Linear
I am using my TR7 with a modern linear and have come up with what can best be described as an irritation rather than a problem. The linear requires only 20watts drive for 400 watts out (our limit). In SSB the only output control on the TR7 is the Mic Gain.It is a real fiddle to adjust this for 20 watts and more so to keep it there. The smallest touch on the gain control can double the output and also it cannot cope with peaks. Modern radios have SSB output level separated from Mic Gain. Any ideas on how to get around this situation? John GI3KDR <>___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] R4C
I have had only one transaction with Radiomart and it was perfectly successful.He offered a Drake RV7 in his usual glowing language. I asked a question which was promptly answered and then bid and won it. The RV7 was packed carefully and shipped quickly. On opening the box I found that the condition exceeded the glowing "sales language" and indeed it was just like new and worked beautifully. The R4C he now offers does look newer in the photographs than any I have seen,and certainly better than the two very excellent units I used to own. I have read of his bad transactions but think some are inevitable when reselling second hand equipment.I used to sell some locally in Northern Ireland about 30 years ago and was caught out a few times-usually with "like new" linears and ATU's with burned out switch contacts caused by hot switching. The important thing is that, when there are problems,things are put right with the customer promptly. That is just good business!

(the S meter seemed to read higher than my other radios by quite a bit). After re-setting the S-meter per the manual, I thought I'd go back over the transmitter settings and lower the output somewhat. I had read somewhere that Drake liked to set the ALC board at 120w instead of the called for 140-150w. The purpose being purity of emissions. I'm using it mainly with an L4B, so the extra 20-30 watts means little. Per the manual, I set the carrier fully clockwise on 14mhz, keyed the radio and set the ALC pot to about 120w. Then went to 28mhz and attempted to reset the predriver board to get the alc light to go out. No can do. The pot is fully CCW and no more there. I remember when I did the previous alignment set at about 145w on 14mhz, and then on 28mhz, the alc light just started to dim at fully CCW on the predriver. Any comments as to what I should or should not be doing? PS, its sn 5300 or so with the version 2 predriver.

Re: [Drakelist] TR7A on Ebay
If the definition of a genuine TR7A is one that was produced in Miamisburg I believe that the following 4 criteria apply with item 4 being TOTALLY critical: 1. Front Panel perspex strip reads TR7A. 2. Serial number above about 11000 (mine is 11365) 3.The spare RCA connector on the back is now used and labelled TX in bold black print. 4. THIS IS THE CRITICAL ONE! There is a screened lead from the RCA connector mentioned and it goes to the board right beside the 4 pin microphone plug. This lead is inextricably woven into the wiring harness that goes from back to front of the radio.When you look at it you will realise that this could only have been done at the factory. I believe this is a conclusive test. John.

I looked them over good. Here's my opinion. 1. A EXTRA nice looking radio, looks little used with original gray case. 2. 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. No "TX" marked jack on rear panel. Nor does the spare RCA jack have the black insulating washer found on most TR7A's.. My reference was 12129 that I previously owned, and others I've seen. 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. One thing is clear. If the serial number is not over 11000 or so, its not a "real" or "authentic" TR7A. It it were mine, I'd find a parts radio and correct the front panel !!

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.

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] Drake TR7 and R7
The exchanges, initiated by Jim, on this subject have interested me greatly as I bought an R7 recently. I bought through an ad placed on the Drakelist by a member and a very successful transaction resulted.The radio is the closest to a "new" Drake that I have ever owned! It has two modifications and I do not know the reason for either of them.I hope members will be able to offer suggestions. 1. The RIT on the R7 should be about plus or minus 3khz It has been modified to plus or minus 200hz. Yes 200hz. Why? 2. An SO239 has been installed on the back panel right beside the Bandpass Filter, and the centre pin of the SO239 is connected to the BPF input.The output from the Antenna Splitter switch unit has been rerouted to the spare RCA connector on the back panel. This has all been done so neatly with wires in the harness that one would believe it was a factory job! This gives two choices: 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.

GI3KDR -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Garey Barrell Sent: 30 September 2008 22:06 To: Drakelist Subject: Re: [Drakelist] TR7 with modern linear John - There are a few ways to do this. I'm not familiar with the Acom unit, but apparently it doesn't require much drive. 1. Construct a "power pad" to put between the TR-7A and the amp input. This is probably the "best" way from a distortion standpoint, but inconvenient unless you use the amp all the time. Running any SSB transmitter with very low Mic Gain is not a good idea, since the S/N ratio of the AF stages is at its' worst. 2. Construct a small power supply to feed a "fake" ALC signal to the ALC input on the TR-7A and crank the voltage up to where you can run the TR-7A Mic Gain at 10-11 O'clock and not overdrive the amp. When you want full output from the TR-7A, just turn off the ALC voltage. 3. Construct your own ALC circuit in the amp using the method in the L-7 or some other amp with similar circuit topology. 4. You "may" be able to turn the internal ALC pot on the TR-7A to limit it's maximum output to a level that won't overdrive the amp. Again, no convenient way to enable full power for stand-alone operation. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line & TR-4/C Service Supplement CDs John Stringer wrote: > Way back in the 80's I used a TR7 with an L7 which ,of course, had ALC. > Everything worked well together. > Now, about 27 years later I have bought a nice TR7A and am trying to use it > with my modern Acom 1000 linear which has no ALC provision. > There is one problem as a result.

[Drakelist] TR7 with modern linear
Way back in the 80's I used a TR7 with an L7 which ,of course, had ALC. Everything worked well together. Now, about 27 years later I have bought a nice TR7A and am trying to use it with my modern Acom 1000 linear which has no ALC provision. There is one problem as a result. I have to turn the drive-meaning microphone gain- down VERY low so the TR7 is operating long before it's own ALC kicks in. As a result there are considerable output swings to the linear which often causes it to kick out. Turning down microphone gain even further helps but then the average output is very low. I need to be able to operate the TR7 so it's ALC is working whilst giving a LOT lower drive. Any suggestions? John.

All it really does is match the 50 ohm output impedence of your transmitter to the impedence it sees at the end of the coax. From the coax connector on, you still have all the SWR and heat loss due to dissapation. Good luck.

Re: [Drakelist] SP75 Speech Processor and C Line
Tom and Alan, thank you for your very helpful comments. I do have fans in my T4XC and also my TR7 and they work well. I mostly use the SP75 with the TR7 and it works fine. I really would love to buy a DX Engineering processor for the T4XC but they are very very rare-maybe one day I will be fortunate!My main concern,aside from protecting the tubes is to keep the good audio quality.

Re: [Drakelist] MS-8 Speaker- $260!
Yes,from here in the UK I notice the accessories will soon cost more than the radios! I would love to have an RV75 but one sold on ebay recently for over a thousand dollars! More than the cost of a TR7 plus PS7. Conversely I notice that T4XC's are remarkably inexpensive. Also Drake items are generally much more expensive in Europe than in the United States.

No hidden tricks. I use a couple of thicknesses of cardboard over the bottom trim strip as a fulcrum for a screwdriver blade. The trick is to pry slowly and under control. The cardboard is to spread out the force against the aluminum trim strip so as not to damage it. Another old time trick is to work the edge of a handkerchief behind the knob and gather in such a way as to give you a bigger "handle" to pull on. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line & TR-4/C Service Supplement CDs John Stringer wrote: > I have tried to pull off the Aux7 and Mode knobs without success!

GI3KDR -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Garey Barrell Sent: 31 July 2008 18:21 To: Drakelist Subject: Re: [Drakelist] TR7A 12v Switching John - Normally, the TR-7 switches both the AC supply to the PS-7 Power Supply - AND - the +12VDC to all of the transceiver with the exception of the PA stage. This was done to allow the transceiver to be used on either AC or DC if mobile use was desired. So if the external 12 VDC supply is ON, turning the transceiver on or off with the PWR OFF switch will turn off all but the PA. The AC part of the PWR OFF switch is connected to Pins 1&3 and Pin 2&4 of the PS7 Control connector (J5) on the TR-7. There was a mod circulating to remove the AC from the transceiver cabinet by putting a relay inside the PS-7 and using the relay to control the PS-7 AC primary. These switches do fail, and are essentially irreplaceable, due to being mounted on a dual control. I leave my PWR switches ON, and use an external power switch. I do this for all my older equipment that has control mounted power switches just because they are so difficult to source if they do fail. I wouldn't just plug in the PS-7 without doing some checking. You can check the continuity between Pins 1&3 and Pins 2&4 to see if the PWR OFF switch is still functional. If it is, then you are probably ok. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line & TR-4/C Service Supplement CDs John Stringer wrote: > I have been using my TR7A with a non Drake Power Supply.

[Drakelist] TR7A 12v Switching
I have been using my TR7A with a non Drake Power Supply. When I do this the front panel on off switch switches the 12v. I always thought this strange as it is supposed to switch the main supply to the PS7. Two questions: 1. Is it normal that it switches 12v? 2. Is it switching the full 23amps or just the receiver part if it is a Drake arrangement rather than a modification? Now I want to use a PS7 instead of the non Drake supply and this leads to question3! 3. Is it safe to plug in the PS7 and will the front panel switch turn on the mains voltage?
