Hi everyone. Haven't had much time for the TR7 due to ill health. However I have the transistor for the 10R line. I wondered what caused it to blow in the first place. I checked the 10R line,for resistance to earth with the test leads in both directions. It read 160 ohms. It looked a little low so I pulled,a few boards which used,the l8ne. if/audio, if filter, switch and 2nd mixer. One pulling the second mixer the resistance went to zero. Tried,another board and it was the same. No wanting to blow the transistor does anyone know if that resistance is correct? Thanks Mike G3ZCC

When I attempt to set the 9 MHz oscillator by listening to the sidebands (per the manual), each sideband sounds "different". It's as if I can get the "frequency" of the sound the same but the bandwidth of the sound is different. It's as if one sideband's filter is narrower than the other one. Does that make sense? I presume it's possible and that one or the other filter's shape is different (i.e. a narrower bell-shape than the other one). If that's the case, then is it an indication that there's something wrong with one (or both) filter that's making them sound different in this way. I know that may sound like a weird explanation of what I'm hearing but it's about the best I can describe it. BTW, 40M seemed terrible at my QTH today. I was hoping I'd hear the net with my TR-4 but I could just barely hear anyone today. Thanks, Barry - N4BUQ

Hi everyone,sad news. I traced the issue,finally, no 10R getting to the filter board, not even on the socket. Checked the 10R on the psu board, exactly 10.0v Removed The front panel and the two banks of switches. No 10R but 13.6 v. On A and B The switching seems,to work though. At a complete,loss now. Last gasp the circuit is hard to read where do the switches derive the 10 R from? Just in case I am missing something. It's the dustbin if I can't find the problem Thanks Mike G3ZCC

I recently picked up a set of C Twins at a hamfest and getting around to checking them out and I am having a problem with the R4C s/n 27279. When I first powered it up I got good strong audio but a few minutes later the audio would drop out and become distorted then it would come back strong a bit later. When the audio was strong it was crisp and clear. When audio drops out and becomes distorted and I have to turn volume all the way up to hear stations. Seems the receive is still good as stations who were S9 while in strong audio were still showing S9 on the meter after audio dropped. This happens in both SSB and CW. The change would happen when nobs like the band or mode were changed but also would happen randomly with no nobs turned or other contact. I cleaned the contacts and switches twice, tested the tubes (all tested good) but still swapped out with known good tubes, and changed the electrolytic capacitors using the Hayseed Hamfest cap kit all with no impact. Was not sure where the two 10uf 35V caps go in the Hayseed kit. I changed out what I believe to be the C175 but did not know where to change the other so still one 10uf not changed. Have tapped around on the chassis to look for loose connections with no effect. Have also probed around looking for cracked solder joints or cracked resistors and none found, at least yet. I am testing the unit as a stand-alone not connected with any cables to the T4XC except the antenna coming into the transmitter SO-239 then to the R4C through the shielded antenna cable. To make sure it wasn’t that connection or cable I put a wire into the antenna jack on the back of the R4C and connected it to my antenna and the problem was still the same. This issue seems to be evolving. Since I’ve been checking and testing, it now seems that the R4C is in the bad audio condition almost all the time and the distortion is worse. I noticed this gradually changed from about a 50% good audio/50% bad audio when I first got it to where it is now 100% bad audio condition. Any direction on what the cause of this audio issue might be and how to correct it is appreciated. Randal KG5IEE

I distanced myself from Amazon a few years ago when they switched to a format where you couldn't identify the vendor before or after the sale. Even before that you couldn't tell if something came from an Amazon "warehouse" or a vendor; the number remaining in "stock" was never accurate with the online readout. Too, when doing a search, I've found prices can be significantly lower on eBay or some of the ham sites that allow free ads. Happy Easter Sunday to all.

I decided to purchase a PLJ-8LED freq counter last month to see if I could get it to work with my R4-C Even though it was $10 higher in cost, I went with Amazon because of their simple return policy and the unit being a Chinese product. The first unit was DOA. The second one worked, but only with my sig gen set to max output. It turns out that some of these units come with an incorrectly color-coded connector for the signal input - the red wire goes to gnd and the black wire is the signal input. After resolving this problem, the unit worked good with my R4., except for 10M. There is a spur 5.645 MHz above the injection signal. If this spur is within 10 dB of the injection signal, the freq display is unstable. This was not an issue on 80-15 M, but on 10 M the spur was only 8 dB down. By realigning the 10 M band I was able to get the spur 15 dB down and subsequently got stable readings. Yesterday the unit died. It displayed all zeros on both high and low channels regardless of freq or pwr level. Went to the Amazon site to try and return it, but discovered that it was 10 days past the 30 day return period. Decided to order another unit from Amazon. When I got to check out, I noticed that there were several unusual entries - no option for shipping method, no charge for shipping when there should have been, and a credit of $1.90 applied for a “promotion”. After searching through all of the fine print I discovered that by placing the order I was agreeing to their promotion, which was to be signed up for Prime for 3 months. Amazon slipped this in even though I had previously checked the box saying I didn’t want Prime. I was unable to find a way to order the part without agreeing to the promotion. Bill N0CU -- Bill N0CU

Good morning ! I’m looking for the case for a Drake 1-A. Can be rough as long as there are no dents or extra holes Email me W5sum at yahoo.com! Thanks Ronnie W5sum

I started checking the resistance values in my TR-4 and found that Pin 7 of V2 is around 355K. The value in the chart is 246K and I'm wondering how that's possible. Pin 7 has a 330K and a .005uF connected to it so I can't see how that can be 246K. Is that a typo and should've been 346K? I know the values aren't meant to be taken as exact but, unless R125 is under it's designated value, I can't see how it could be less than 330K but perhaps I'm missing something about this circuit. Thanks, Barry - N4BUQ

Hi all, I have a TR7 i just received, but no microphone to go with it. My question is: what mic would be good to purchase for use with the TR7? A Shure 444d desk mic has been suggested, and there are plenty available, but what hand mic would be equivalent ? Is there a Shure hand mic model that I should look for? If you have one for sale, please contact me, my info on QRZ is good. Thanks for your response and suggestions in advance. 73, Robert WD8PAQ
