Re: SSB Preamp



Also, most TX amplifiers have a series capacitor on the input, which will
also block the DC power.  With the TX amp switched off/out, there is usually
a DC path, but check the schematic.

Not sure what you mean by "recognized a preamp" (I don't have a 910), but if
you have a lightning arrestor in between the rig and the preamp, they
usually block DC from passing.  Mine does, so I had to power it with an
external cable (which, now that I think of it, kind of defeats the purpose
of the lightning arrestor...!).
