So did you end up with both 360pF caps together and the 2 500pF caps together or one of each together?
Mike - sorry for the delayed reply - been in football mode all day and just this evening got the time to unscrew those damn 16 screws holding the cabinet on to take another look! Here's the status on my AL-811:
It came with a 360 pf cap that appears to be switched in when the band switch is on 40, 80, and 160 meters. I did not mess with that one. There were two others installed at the factory - a 360 pf and a 500 pf, both of which get switched in for 80 and 160 meter operation. Ameritron mailed me a new 360 pf and a new 500 pf. I clipped out the 360 that the factory had installed for 80/160 and replaced it with the new 500 they sent, giving me two 500's in parallel. That helped but I still wasn't satisfied. I then soldered in the new 360 that they sent me, giving me two 500's and a 360 in parallel.
So......, what I've got now is the original 360 when the band switch hits 40 meters, and when it gets to 80 and 160 meters, there are 1,360 pf additional being switched into the circuit.
Like I mentioned in my last post, it works OK for my 80 and 160 meter CW operation. More than likely far too much capacitance for the higher end of those two bands. But I have no way of trying it. YMMV
Hope that helps.
