[TenTec] Omni 546C Muting

[gary nichols]

I had a similar problem about 10 or 12 years ago using my Ten-Tec Corsair II
to drive a Kenwood TL922A linear amplifier.  At times the Corsair would
stick in one mode or another.  Now many years later I understand the problem
being the T/R relay was "insufficient" for the voltage and current required
to pull the keying line of the amp to ground.  This is not a "new" problem
and in fact is getting more severe as newer transceivers have smaller
lighter T/R relays.  It would appear that the new rigs are designed for QSK
type amplifiers which require only a few milliamps to key them.  An old
SB220 or  TL922 would "kill" a newer rig in short order without a "keying
relay" buffer between the two.  Icom rigs appear  to be the most succeptable
to this problem...de gary, kd9sv
