Actually, JT65 requires a bandwidth of 2.5 kHz or more. Set the radio to USB and follow K1JT's directions. You didn't ask about RTTY, but the Orion II works equally well in pure FSK and AFSK. For AFS
Looking at T-T's Web site, I see that they've taken electret condenser mics out of their product lineup. All the mics currently offered are dynamic. Wonder why. 73 Ray W2RS
Hi John, You'll probably get as many answers as there are people, since a lot of this boils down to personal preference. Here's my take. I'm using a US Interface Navigator, which I like a lot. It's e
Cecil, I find that the best SAF setting for me is 20 Hz, and tuning the center frequency +'- 10 Hz around my SPOT frequency of 350 Hz. Really helps bring weak CW signals out of the noise. 73 Ray W2RS
Cecil, Right on. The RF gain setting is critical. I set it by ear, don't know any other way of doing it. I used to use an external Autek QF-1. The O II SAF is better (less ringing, easier to use) if
Not only that, but the old Collins spec was 3 S units = 10 dB, not the modern standard of 6 dB per S unit. More broadly, I'm afraid I just don't understand the continuing preoccupation with S meter a
Kim, I just checked my O II. Cranking in ATTN does affect the S meter reading, as does switching the preamp in or out. If you reduce the RF gain, the S meter will rise unless it is below the noise le
Barry, I've been experimenting with my SAF BW, RF gain, etc., and I still find that 20 Hz is the best setting for me in bringing up weak signals. At 10 Hz, the signal is about as strong as at 20 Hz,
Mike, In addition to the spectrum display issue, I have a problem that there isn't enough TX audio gain to support the 707 Regal mic without distortion. That wasn't a problem with v2.044A. Until they
