Hello,
In response to Michael Morrow "<[email protected]> in response to myself:
>>Resistance (p. 45): ground (-) to J8 pin 5
>> should be 90-110k, but I'm getting 1.5k.
>I'd suggest re-checking the orientation of D15.
I re-checked it, and the banded end is indeed facing left. (No luck with spontaneous change of resistance, either.)
>> D11 cathode should be 4.0-4.6, is 0.8
>I don't know about that one. Are you
>sure you had the positive lead of your
>voltmeter connected to the junction of
>D11 and D12?
I'm not sure what I had wrong before, but it now measures as 5.1v. I think I /may/ have been measuring the wrong diode or wrong end.
>> if I readjust L1 (for the VFO), ...
>So, you can adjust L1 turn spacing
>after the earlier band calibration of

>accurate LCD display of the receiver
>frequency.
O-/kay/. I readjusted L1 so I'm closer to the bottom edges, and get a smidge more of 15m.
Thanks!
