[drakelist] Dumbish Question

Hi all, Sorry for such a basic question, but I've been wondering why Drake made both a transceiver (TR-4C) and a receiver/transmitter pair (R-4C + T-4XC) in the same line. Did the separate receiver/transmitter pair offer better performance than the transceiver in some way? I would

[EMAIL PROTECTED] made an utterance to the drakelist gang -- The C-line allowed split operation and to do this with the TR-7 required the external RV-4 VFO or the later TR-4C with RIT. C-line enabled cross band operation.

The separates also have: Selectable IF filters (if you populate the optional positions) Notch filter 3 selectable AGC time constants (and Off) The potential of a superior receiver (according to the modifications and measurements from Rob Sherwood - and others) Dave VE6DRW - Original

Re: [drakelist] Dumbish Question

Hi, most importantly the receiver, R4C, had the provisions for additional filter options both AM, SSB and CW. The TR4C later came out with the TR4CW which had a narrow CW filter built in. This transeiver was mainly a SSB unit until then. Another plus of the R4C was variable pass band tuning

[drakelist] TR-4C

I have a TR-4C that is losing the 9 mhz signal in T14. I assume the diodes are out. Is this repairable or is the thing junk? Terry, W8NJR **Create a Home Theater Like the Pros. Watch the video on AOL Home.

Re: [drakelist] TR-4C

OK thanks Gary. I thought it might be the diodes. I have 9 mhz signal going in and nothing coming out of T14. It looks a little tricky getting T14 out but I think that is the next step. I'll let you know what I find after I get it open. I better order some diodes!
