K0KR reminded me of a few more 990 attributes:
- He says that the transmit audio sounds quite good (for contest use) when
the processor is properly adjusted.
- When used with my Alpha 76PA and VOX keying, the 990 initially transmits
at about 50% of full power. Over a second or two, the power rises to
full power. It seems that the relay(s) in the Alpha are slow to key, the
990 detects a high SWR, and shuts down, taking several seconds to recover.
This happens on both phone and CW when using VOX (but not PTT). K0KR's
Drake L4-B linear doesn't have this problem with the 990 (a faster acting
relay, no doubt). Also, my TS-940S doesn't have this shutdown problem with
my Alpha.
- I really like the SCAF filtering on the receiver audio. It's more
effective than I expected.
