An interesting article I read in the IRTS news bulletin:
Many of us are familiar with the work done by Rob Sherwood NC0B over the years to identify rigs with poor strong-signal performance on receive - of particular relevance to contesters and DXers
Jim Brown K9YC has now done a similar exercise, except he has measured the trash (key clicks, inter-modulation distortion, and phase noise) generated by some popular
rigs on transmit. If you're thinking of buying a new rig, it's worth reading this first.
