looking for XG3 amp...

[John Ragle]

Anyone know of a 1 -- 5 watt amp for the XG3? ... I would be
particularly interested in a small 6 meter narrow-band amp as a kit.

Bear in mind that the XG3's synth chip has a fairly constant -105 dBc/
Hz phase noise at all frequencies -- about 30 dB worse than typical  
high-performance transceivers. You wouldn't want to follow it with a KW.

To use it as a multiband transmitter, you'll also want to provide a  
way to shape the keying (at least for CW) and you'll need low-pass  
filtering.

How much power could you get out of a simple 1 transistor amp on 6m with the XG3
driving it?  Maybe that could be an easy way to make a real 6m beacon if it had a
little 12 VDC amp following it...  VY 73, Lance
