Harris RF-590:

* Good sensitivity down to 10 kHz
* 10 MHz reference input
* noise blanker works well
* 4 agc settings + off
* multiple filter positions
* 1 Hz tuning steps
* variable BFO pitch
* calibrated signal strength meter
* scan and other misc. bells and whistles

Only drawback I've found is filter "blow by" with very strong signals.
Probably an easy fix - I just haven't got to it.

Jay, W1VD
