[drakelist] TR-4C Help needed.
Hello I need some help for my TR-4C which I have bought as beeing OK, but was not. Hopefully someone are able to give me some useful ideas. The receiver seems to be OK on all bands. But something is wrong on the transmitter side. I have added a table to show what happend if I try to tune on the different band. 80m 40m 20m 15m 10m LSB USB LSB USB LSB USB LSB USB LSB USB BIAS OK OK OK OK OK OK OK OK OK OK Drawing Current for tune NO YES YES NO NO YES YES NO YES NO All the voltages from the AC-4 seems to be OK. When I push on the relative output nothing happend when I try to tune up. Thanks in advance. 73 Bent OZ5ZD

CW and tune up only work with the sideband switch in the X position. I believe the behavior you observe is normal. Once tuned up, you can switch to the sideband you want to use for SSB. 73, John W1JA Web site http://www.radiophile.com - Original Message - From: Bent To: [EMAIL PROTECTED] Sent: Sunday, May 25, 2008 5:46 AM Subject: [drakelist] TR-4C Help needed.

Gary Poland [EMAIL PROTECTED] made an utterance to the drakelist gang -- Bent, Is receive good in those positions? Is the carrier oscillator close to 9 mhz? If you cannot get RF output in the X filter position and receive sounds poor you may have a bad LSB filter. This is not uncommon. 73, Gary W8PU http://home.cinci.rr.com/w8pu -- Submissions:[EMAIL PROTECTED] Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --
[drakelist] TR7 2nd IF Audio board
Hi, Does anyone know about when, by serial number, Drake went to the newer version 2nd IF-Audio board? As much time has passed, I know that unless one is sure his/her radio is original, it may be hard to tell due to possible board changes before the current owner. But does someone out there has a good idea? FYI, my current TR7 is SN, 5392, split rear panel, late version NB, Late version pre-driver, early version digital control board and early version IF/Audio. I may be wrong, but the NB is likely a newer addition. I did notice that my IF/audio board has been repaired, an IC replaced and a poor soldering job that I had to clean up. I guess, bottom line, I'm trying to figure out if my audio board is original to the radio or not. Thanks, David WD9CMD

Don Cunningham [EMAIL PROTECTED] made an utterance to the drakelist gang -- Tom, From my saved Drake archives, Garey Barrell reported the change was around s/n 6000, so yours might well have had the version 1 or 2 as original. 73, Don, WB5HAK -- Submissions:[EMAIL PROTECTED] Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --

David Chris Drake [EMAIL PROTECTED] made an utterance to the drakelist gang -- Thanks, the 6000 number does make some sense of the ones I've seen. You never know with the number of parted out 7's out there today. If anyone out there has a 7 with the first version board above 6000, and you think its stock, let us know. That would be good to put in the book.
