[Elecraft] K2 Update TS information

[Jess Gypin]

Still chasing the problem with the SSB board.

1. Rig works fine with the SSB option removed and jumpers reinstalled.
2. 8V is present on pin 10 P1.
3. C42 was left out by my mistake, installed.
4. 8T at pin 3 P1 is only 7V DC. There is 2V AC present.
5. 6V out of the 78L06 fed by 8V is only about 1.75V DC, no AC present.
6. With the power turned up at all, radio will go into TR/RCV oscillations
and show over current. I only allowed this for a second and have not tried
again. With the power all the way down, it is fine.

So, you can see that the 6V line is only 1.75V and that is probably why the
front panel is not working with the SSB board in. No logic voltage to the
digital chips.

I am still tracing and scratching. Still cannot figure out how the 8T
oscillations and 8V problems are related. Circuit is not that complex.
Complex enough for this old brain I guess. ;-)
