Hi,
My K2, recently completed, has developed a 'howl' on the 14MHz band.
I had finished the rig and got it tweaked and performing very well,
even making a contact with K6STA on 20 meters (He gave me 579)
I then constructed the KIO2 and got it working with my logging program
(tlf).
The KIO2 began to malfunction, so I took it out and re-did the wiring on
the aux board.
I replaced it and it seemed to be fine except for a brief glitch.
Then I noticed that there was a 'howl' all across the 14MHz band, but
not on any other band.
I removed the KIO2 and set up the rig. The howl was still there, exactly
as before.
What could have happened?
I noticed that touching the leads of R24 or R25 modified the noise, but
that's about what I know.
The noise covers the whole band as far as I tuned.
Anybody got a suggestion for how I should start troubleshooting?
Thanks
