Better yet to generate the best transition waveform in data (far more difficult to do in analog methods) and via a DAC create a completely clean signal at the TX IF level. Then only conversion and RF issues to keep clean. Then adjustments to waveform are in firmware. 73, Guy. _________________ Topband Reflector Archives - http://www.contesting.com/_topband
