[R-390] R-390a/SSB Convertor

[Tony Angerame]

I am using an R-390a and feeding the if output to a Rycom Selective Voltmeter. The Rycom has a product detector with selectable USB/LSB, bfo, am and fm detectors. I works well on all modes but I am skeptical that I actually have the received ssb signal centered in both the passband of the r-390a mechanical filters and the Rycom crystal filters. Right now I simply peak the Rycom on receiver noise, select the appropriate sideband and tune the r-390 for intelligibility but this cannot guarantee the ssb signal is centerted in the r-390a passband. I was thinking of using my xmter as a generator and injecting, say a 2.0 khz audio and centering it in the 4kc passband just by carrier stregth. I have a feeling that because of this I am tuning signals on the r-390a at one end of the filter passband.


Thanks,
