[TenTec] Triton 540 low audio on SSB??

[Bwana Bob]

That's correct. The older rigs were designed for Hi-Z mics. Also, the 
540 may not provide the DC voltage necessary for an electret mic. You 
may need to put a battery inside the mic. The Ten Tec desk mic has 
provision for an internal battery. The older Ten Tec hand mics also had 
a space for a 9V battery inside, but the current one does not. Current 
Ten Tec rigs provide about 4V on pin 4 of the mic. jack. My Corsair has 
7.7 V on pin 4.
