Got my XV50 integrated into the Intergalactic Roving Batttle Jitney
(TM) yesterday, and I'm QRV with 400 watts .. K2 feeding XV50 feeding
TE Systems amp. I got a hold of a buddy of mine about 30 miles away
for some on-air testing while I diddled around with SSBA/C settings.
Problem is if I enable *any* level of compression, the XV "buzzes" on
voice peaks and my signal sounds crappy. Best results were with SSBA=3
and SSBC=1-1 (using an MD-2 desk mike). Evidently some of the RF is
making it's way back inside the XV. Cabling is all good, shielded
cable to key the amp/Accuvolt, normal shielded auxbus cable. Even with
the 1-1 setting I get the buzzing whenever I drive the amp much above
300W.
Anyone else seen this and/or have any suggestions? I'll be setting up
144 and 222 this evening, but they don't have quite the power
capability of my 6M station .. I'll report in the next day or two
whether they show the same behaviour ..
