Spectran (Audio Spectrum Analyzer)
Spectrum Lab (Audio Spectrum Analyzer)
I have used these in combination with my noise bridge to characterize crystal filters in the
ATS3
.
FT817 (siggen/counter/wavemeter/etc)
I find the FT817 to be a great piece of test gear.
I have used it in combination with Ham Radio Deluxe as a spectrum analyzer
to check the harmonic output of some qrp rigs.
