I built a homemade AUX7. I populated it with 30M and IIRC 17M and 24M. - Jerry, KF6VB

Lyndon, I have a TR-6 with all the filters.? What do you need? 73, Bill, K3PGB

Hi Gary, No I have not seen the frequency change but I have never left that way more than a few minutes. I already decided to clean the back switch and the molex pins etc. I will do that as soon as I

Another Christmas Day survey :-) 1) Does anyone here own a TR-6 with a CW filter installed? (I do not need to hear from all the people who DON'T have a CW filter.) 2) If you don't have a TR-6 CW

Does the radio wander up to this frequency and then sort of slowly stop wandering? The local oscillator in this radio is simply the output of a VCO in the synthesizer, one that uses the analog PTO as

Merry Christmas! A quetion to ponder as you gaze in wonder at the TR-6 Santa left for you under the tree ... If you had your choice of any eight band modules to populate your AUX-7 with, what would

I now have the receiver and transmitter working good. The problem now is that the 15 and 10 meter bands do not work. The display shows the frequency in the photo. I am trying to find time to read how

Do you remember how you removed the stop in the band selector??Sent from my T-Mobile 5G Device

Yes it had the band pass filter. I removed it. Now to "unlock" the band selector and add a capacitor.?ThanksRogerSent from my T-Mobile 5G Device

I am going from memory and do not have a manual in front of me. So here goes. The incoming signal to the R-4C is converted to the first IF of 5.645-MHz. In the second mixer, SSB and CW signals are

Yes. Rob

Rob, Connect my service monitor/counter to the CAR OSC jack, and adjust C6 for exactly 5645 Khz? Tnx&73 Jay W6CJ nc0b.com_at_groups.io_lastradioman@...> wrote:

The R-4C derives passband tuning by using a tunable 50 KHz oscillator (BFO) to first heterodyne the 5645 KHz first IF up to 5695 KHz. It then uses that same variable BFO to feed the product detector

The 5645 kHz LO from the transmitter if off frequency. Rob, NC0B

Yes this looks spot on! Thanks Jim... I also attached another view with the old suppressors installed with the factory straight wall chimney's. the tapered version is what Eimac recommends, along with

Group, I have my "new" Twins hooked up and making QSOs. I noticed that with the R4C in LSB, and passband on the LSB "dot" for best LSB reception........ when I turn on the T4XC, I have to re-tune the

I started out with Drake back in 1975 with a TR4C. I used the C line as the main station until 2001, still have several T4XC's, 4 in fact and one R4C, several R4B's, 2C and 2B and amps. I also have
