RE: [drakelist] Help with unlocked TR7
Walt, I had my TR7A do this to me - it turned out that a violet wire that ran from the DR7 to one of the bandswitch wafers was not making good contact. A bit of DeOxit put it right. Maybe you will be so lucky. Win W5JAG From: "LEWIS WALTER" <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: [drakelist] Help with unlocked TR7 Date: Sun, 25 Jan 2004 08:39:01 -0500 I just purchased a used TR7. When I power it up, all of the display lights come on, but the dsiplay reads something like 96Mhz, with some flickering up/dwn a couple of herts. Turning the band switch and using up/dwn buttons has no effect. The store button does store the (erroneous) freq I can't tune in any signals, but all of the rest of the rig seems to work - ie af and rf gain, filter switches, etc. I would guess that either the synthesiser isn't locking, or some other osc isn't wrkng. From looking at this bulletin board, it seems that reseating a card might wrk. How do i identify the right card, and how is it pulled without damaging something? I don't have the service manual yet. Anything I can quickly do to check this out? Is it usually an easy problem to fix, or is it something drastic? It is a fairly late model TR7, around 10,000 s/n Also, how do I pull the ckt boards to reseat them. Can the edge connectors be cleaned? Finally, anything in general I should be checking to get the rig in overall shape. Your help would be greatly appreciated! 73 Walt _ _ Add photos to your messages with MSN 8.

[drakelist] TR-7 bandswitch
Before I pull the back panel bandswitch mounting plate and lose what bearings may be back there, anyone have a "suggested" method for removing the TR-7 bandswitch? Any gremlins to watch for? I need to replace PIN diodes on the HPF and LPF boards, and while it looks do-able without pulling the boards, I'd like to check other components while I'm in this radio. Thanks. 73, Russ WB8ZCC -- Submissions:[EMAIL PROTECTED] Subscribe: [EMAIL PROTECTED] - subscribe drakelist in body Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Brought to you courtesy of TLCHost.net http://www.tlchost.net/ --
[drakelist] T-4x Alignment
Hi Again All; Cleaning the switches appears to have corrected the intermittent tx problem, for now. Not sure if more cleaning will help the output on 20 and 40M? I was able to tune the rig on 80 thruogh 10M. The output is approx; 80M = 30W 40M = 140W 20M = 25W 15M = 100W 10M = 75W I want to try aligning it per the manual and wondered if there were any hidden land mines to watch out for. RF and mixer stages instructions 3 to 10 have you peak the inj with a sig gen. Steps 11 to 18 have you do the rf with the vfo. During steps 11 to 18 do you re-peak the inj with the rf in any particular order? Can I use the rx to peak the 160M band? I dont have a 160M tx xtal. The rx does have a 160 xtal. Does it matter if I dont peak the 160M band? Dont have an antenna for it anyway. I have not tried the rx & tx as a pair yet. Want to get the tx up to snuff first. I appreciate the help. Thanks in advance for any suggestions or advice, George KB2Z
[drakelist] 6jb6 tubes
Good day to the group, Was going through my stash of Drake goodies and found something that might be of interest. I have a matched set of three Sylvania 6JB6 tubes. These tubes are new and in the original packing material packed in the box as shipped from R.L. Drake Co. UPS label is dated Dec-6'76. Box has been opened to inspect contents. Tubes have been tested. Do not like to do this but, since I have no idea what something like this would be worth, I will entertain any offers(RFparts matched trio $88.50 doubt they are Sylvania). If interested please contact direct. tnx es 73 Garry [EMAIL PROTECTED] -- Submissions:[EMAIL PROTECTED] Subscribe: [EMAIL PROTECTED] - subscribe drakelist in body Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Brought to you courtesy of TLCHost.net http://www.tlchost.net/ --

[drakelist] 2c Parts needed
I bought a 2C parts radio with the intent of having it for just the parts but the darn thing works. I am not going to try and restore it like new, the chassis is nasty, but would like a few needed parts to make it usable. I need a front panel, condition not important, the hollow shaft for the band filter switching, knobs, the 11 MHz and 18 MHz crystals, and if possible a cabinet. 73, Gary
RE: [drakelist] T-4x Alignment
I don't know about the others but the biggest pain for me is checking the height of the ganged tuning slugs. They have to be set exactly per the manual and I think the difference between some of them is only about 1/32 inch. Had an old one where the tuning mechanism had slipped a little and I couldn't tell if the slugs were white or yellow. They looked somewhere in between. Tried the alignment using the white settings and it didn't work. Found out they were yellow after all. But it still never worked right on 10 meters. The trimmers were out of range and I couldn't neutralize the finals. It worked as expected up through 15 but on 10 things fell apart. Turned out to be the parasitic plate chokes. You wouldn't think it was important but something must have happened to those 2 watt resistors over time. They went up in value to about 62 to 68 Ohms. It didn't seem important but replacing both of the chokes fixed the 10 meter problem. It became apparent when I used a return loss bridge to check the final tuning circuit. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of George KB2Z Sent: Monday, January 26, 2004 12:48 PM To: [EMAIL PROTECTED] Subject: [drakelist] T-4x Alignment Hi Again All; Cleaning the switches appears to have corrected the intermittent tx problem, for now.

[drakelist] TR7 Volume
I just acquired a TR7 that works great except for the volume control. It won't reduce the volume all the way even when fully CCW and ready to engage the off switch. It appears to be a ganged volume/on-off switch. Anyone had this happen and if so, what's the fix? 73, Bill NZ0T
Re: [drakelist] TR7 Volume
Hi Bill, Thats normal, mine does that too. Something about the value of the pot at max resistance doesnt silence the rig. Slightly annoying but eventually you get used to it. 73 Mark W0NCL
