Sam, Sorry for the delayed response, it has been a busy day and have not had a chance to get to my email.
OK, the voltages on D11 seem out of "wack" - so check the tinning of L16 leads, the soldering of RFC4 and D11. Once you get proper RX voltages on D11, try the TX diode voltages if it still does not work. 73, Don W3FPR On 11/22/2011 11:53 PM, scramac wrote: > Don, > I made some diode voltage checks and here is what is got: > > Anode Cathode > D9 ref: 1.41 (13.6 actual) ref: 13.8 (13.3 actual) > D10 ref 0.0 (0 actual) ref: 14.1 (13.6 actual) > > Anode > D11 RX 0-10w ref 14.1 (actual: seem floating in mv range) > RX 11-110w ref 1.5 (actual: seems floating in mv range) > > D12 RX 0-10w ref 14.1 (actual: 1.4V) > RX 11-110w ref 1.5 (actual: 3.6V) > > D13 RX 0-10w ref 14.1 (actual: 13.6V > RX 11-110w ref 1.5 (actual: 1.4V) > > D14 RX 0-10w ref 14.1 (actual: 13.6V) > RX 11-110w ref 1.5 (actual: 1.4V) > > Visual check doesn't show anything wrong.
