Excess to my needs – A G0MRF 300W Class D amplifier for 630m.  This amp is assembled and tested.  You may repackage as desired.  Heat sink and RF connectors are included.  Power supply rqmts are 24-28 VDC .  Measured efficiency is ~88%.  This is NOT a linear amplifier and not suitable for SSB or PSK use.  Appropriate for CW, WSPR and other digital modes.  It features SWR and over current protection  I’m selling as I have a wealth of power amps for the band…

Operation and construction details are at David’s site, here:   http://www.g0mrf.com/

USD $ 115.00 includes domestic shipping
