Has anybody successfully modified the Icom IC-251A 2M all mode rig so
that it will provide only 1 mW at the antenna terminal to drive a transverter? On the schematic, it looks like there is a plug that supplies the 13.8 Volts to the PA and driver transistors. If I removed this plug, effectively killing these stages, might there be enough power leaking through to provide the 1 mW at the antenna jack? If so, how bad do you suppose the harmonics would be at the output? Any other ideas appreciated (I could control the power using the mic gain control down to some lower power such as 1 Watt or so and then use a 30 dB pad. Down side is if I ever adjust the mic gain to 10 Watts out, I'd pump 100mW into the tranverter until the 30 dB pad finally blew)...What say??? Scott N0EDV |
