Jim, I believe Drake engineers "balanced" things out for performance and cost considerations. ?But you're right, a higher CFM blower with curved chimneys might be an improved alternative. Have a

Good day Jim, Thanks for the suggestion(s). So PTT / VOX switch in PTT position or VOX setting no change. All controls full CCW? tone initiated immediately on selecting CW.? Meter reads about half

Hello Jim Thank you very much for these important information. That means, as soon as I have build these cables, I will be able to "go on air" with my 4C twins, which I have bought 1 week ago. Br.

The definitive answer is below, from Garey K4OAH (SK). ________ All original cables were 38" long tip-to-tip. The INJ, (and CAR OSC in the C-Line,) cables used a foam inner dielectric and phono

Yeah, it shouldn't do that. Under some conditions a TR7 can pop into TX if the VOX is enabled and you rotate the band switch to CW. Ensure than VOX is off and set all of the VOX controls (both SSB and

This has been a great learning process and a lot of fun. What I now believe the issue of crazy S-Meter readings is due to the frequency of the Second LO Crystal (5,595 KHz) being off frequency. In the

Sorry, I forgot to state that in my original post.? Makes no difference if there is a key attached or not.? Just a steady tone as soon as placed in CW position and no RF out until the key is

Hello to the Group Is someone able to inform me about the correct type of cable for Carrier Osc. an Injection for the T-4XC and R-4C. I have heard about RG59 and RG62. What is correct ? What is the

I am not an expert on the TR-7 but other Drake transmitters have shorting switches in the key connector so that they are key down with no key attached. This is to allow tuning up without a key. Does

Great catch Bob! Gary W0DVN

Whoops, looks like the Translator board has some TTL. If the PLL is locking and you are getting correct stable frequencies that means it survived. Everything else that's digital looks to be CMOS. 73

Well definitely come back and tell us the results. We want to know if its fixed. Might help someone else. -- Richard Knoppow 1oldlens1@... WB6KBL
