What is so wrong with an intermediate amplifier? I have been using this
approach for over 25 years. If properly designed it should produce a very nice
and clean signal.

Subj: Re: [Flexradio] 144 and 432 - Low vs High Powe
Jim,
As an owner of four Lunar-Link tube amps driven by DEMI high-power
transverters, I have to agree with Mike. 50 watts of available drive
power from the transverter is considerably more convenient than adding a
brick amp into the system with existing HPA's or having to roll your own

I have not seen any significant discussion on the use of the 5K flex-wire
port.
I would like to know if anyone is using this port, for what purpose and how
it is accessed.
The 1000 port was (and is) very useful (to me) for switching antennas when
connected to

David,
I can answer the second question now:
The SDR-5000 series Internal transverters will use the .5ppm 10MHz internal
tcxo and you may select to use a external reference just as the SDR-1000.
