[Elecraft] K2 SSB problem--follow-up

Boy, is my face red. For the benefit of those who helped with suggestions concerning my SSB issue (power output pegging and out of control on PTT), I must confess that when I began looking at this again (for the first time in several years), I had completely forgotten that when I removed the SSB

Doug, Well, stuff like that happens to all of us at one time or another. When it happens to me, I just jot down a Dear Dummy note to myself and go on with life. Glad to hear you found it. 73, Don W3FPR Doug Heacock wrote: Boy, is my face red. For the benefit of those who helped with

[Elecraft] K2 SSB Problem

I just finished constructing the KSB2 Adapter and have installed the unit and am at the alignment stage (P-19 of the manual). The Course Carrier Balance Adjustment went fine. When I plug in the microphone and try the fine Carrier Balance Adjustment the unit begins to transmit at full

[Elecraft] K2 SSB Problem

Hi, I just finished installing the KSB2 module on my K2 QRP version (full optional). I go to operate for the first time but when I push the PTT I get this problem: the current absorbed increases (the voltage decrease) until it exceeds the value 4 A (set at this value after some test) and the

Re: [Elecraft] K2 SSB Problem

Fabio, I cannot be specific, but the most probable area causing that trouble is the area of Q2 and Q3 (those direct the BFO signal either to the balanced modulator in SSB mode or back to the RF board for CW) or the balanced modulator U5. Check carefully to be certain diodes D5, D4 and D3

[Elecraft] K2 SSB problem

Hi group! I have a little problem with SSB it seems. During the contest last weekend someone told me I had frequency modulation on my signal. Not knowing what this should mean I at least thought I would check the signal when bands are quieter. I just did. And although the audio sounds ok there is

Re: [Elecraft] K2 SSB problem

Hi Gerhard, Most reports of FM'ing I have been aware of have been due to a low power supply voltage and/or the voltage varying with the load. I have not heard a K2 with this problem, but it might be worth checking the power supply. gl Trev G3ZYY In message [EMAIL PROTECTED], Gerhard
