I’m sure it is the equivalent of a “security key” for IP protection as well as
a convenient distribution vehicle. It’s also a way to provide updates by

You know something? I too, might be categorized as an appliance operator and

Bill,
I assume that the 1296 transverter is double conversion to get to 28 MHzI IF,
whereas the 222 box is single conversion.
The extra conversion needs some take-over gain to minimize the losses of the
extra mixer in the chain.
It wouldn’t surprise me to find out the 1296 machine has an

I'm not trying to start something, however your definition of affordable cost
leaves me a little mystified.
The overwhelming costs to do VHF/UHF (whether as an SDR or not) include every
component of a transverter: Mixers, oscillators, band-pass filters, power
amplifier modules, T/R switching,

Yes, of course. That's why I cautioned to make sure the power
handling of the coax was up to snuff. There is an absolute power

A cheap piece of RG-58 or smaller (lossier) coax of the right length attached
to the input of your amp is a guaranteed way to make it work right.
You want a 50/20 = 2.5:1 attenuator

What do the VHF/UHF Flexers consider the optimum way to use a FLEX-5000 on 222

Anyone know how the 2010 version of DEMI 222-28HP compares to the previous
