Re: [Drakelist] TR7A band change problem

I recently repaired this exact problem on a TR-7 that I have here. When I changed bands with the band switch, it would stay on the previous band. If I switched the AUX switch to 1 and back, it would change to the band selected by the band switch. I did not have an AUX-7 installed. My problem

Re: [Drakelist] T-4X fan mod

Well, so much for my genius idea. First problem, the voltage jumped to 34.3vdc static. Then I forgot to think. When you double the voltage, you half the current. Now the fan will not run at all, not even start. I could keep doing stupid things but decided to go to the old 12vdc fan I had that

Re: [Drakelist] T4-X Zener Diode D6

Eddy - WHOA !! The Zener is NOT inside the PTO can in the T-4X. It's over on the BAND OSCILLATOR board (near the BAND crystals). It is used to regulate both the BAND OSC and the PTO. The Zener IS inside the later PTOs. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-B, C-Line& TR

Re: [Drakelist] T4-X Zener Diode D6

Hi David, Yuchhh...!!! That news I did NOT wanna hear! Hi Hi Either I was too pre-occupied to notice when I had the VFO open the first time, or the parts are VERY well hidden there...but in all honesty I don't recall seeing Q1, Q2, or D6 inside that can...I guess I'll HAVE to this time around,

Re: [Drakelist] TR7A band change problem

All, I have e-mailed Demis, and the problem is: When the BAND switch is rotated, the rig does not move bands. Then if you move the AUX switch from normal to 1 and back the rig then changes bands. This is occurring on all bands. For example: Currently on 80 meters, and use the BAND switch to g

Yes. Be careful not to wildly disturb the physical placement of the other components. Good luck! David Assaf, III W5XU From: drakelist-boun...@zerobeat.net [mailto:drakelist-boun...@zerobeat.net] On Behalf Of Edward Swynar Sent: Sunday, November 07, 2010 6:56 AM To: drakelist@zerobeat.net Sub

[Drakelist] T4-X Zener Diode D6

Hi Guys, A quick question before I start dis-assembling my T-4X here to replace zener diode D6 (a 1N714, at Q1 VFO buffer)... Is this rascal inside the VFO can...? When I had this shield removed a week ago to clean the guide shafts & add a ground strap (to address my frequency warble issue), I
