I just checked and I was not able to locate an extra L37. However, I do have a friend that has a couple parts radios, he may have an extra D858 board laying around somewhere. I will check with him and report back when I can.
~Cheers~
How awesome is that, man. I don't know what to say other than a big "thank you".
Update 1: USB, channel 19, ALC 180 degrees out, mic gain down, carrier balance adjusted to null out needle...
Lowest bias reading I can get is around 75-80 mA...
One thing I noticed is that it's difficult to null out the needle absolutely on the radio with the carrier balance. With my reading glasses on, I noticed that the needle was not quite all the way over before. About the only thing that works is dialing down L39, (in conjunction with fiddling with VR4), which drops SSB output significantly.
When I get it so that the needle stays ALMOST at ABSOLUTE "zero" on SSB keyup, I can only get 5w avg on SSB and AM, but I get lower amperage readings when biasing the final...perhaps I am getting some stray signal over at the final which may be causing me to be biasing it too low, because that 70 mA reading may actually be something far lower, which may be contributing to this low output issue...?
I know if I was a competent tech who was familiar with this radio this would be 1-2-3.
Quick note- biasing the 2166 driver was a snap; checks out at 40 mA from the minute I
dropped it in and biased it the first time.
I will check out continuity on L37 and update soon.
