Don, Thanks for your questions and helping me work through this. The RF voltages I'm seeing are (on 30 M) are:
PRE - .068 ATTN - .023 OSC - .014 MIX - .105 BUF - 1.37 TR1 - .62 BPF - .076 The DC voltages on page 46 were all within the ranges indicated. The output power in tune show P0.1 on all bands except 15M, there it moves up to P0.3 and stops there. I'll check the RF voltages at all points on all bands tonight after work... 73, Denny On Feb 29, 2012, at 10:17 PM, Don Wilhelm <[email protected]> wrote: > Denny, > > Tell us more - what band, and what > rf voltage are you reading at the Transmit mixer output (pin 4) How > about th DC voltages? > > 73. > Don W3FPR > > On 2/29/2012 10:04 PM, Dennis Rayfield wrote: >> I've build an RF Probe, and worked through the transmitter signal tracing >> section.
