Low_Boy,
TX voltage to pin 5 of your mixer comes from pin 8 of the (IC4) MB3756 Switch/Regulator.
My dumb mistake. I was not keying the microphone. So now I am only missing the pin 2 output. Possibly another bad mixer. The replacement mixer came out of a parts radio that I never actually saw work. Could this be a internal mixer problem?
Incoming Region Produces X3 Solar Flare |
May 15, 2024 @ 14:55 UTC |
Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned |
