Re: Multi band Transverter (2m-23cm)

Probably not at an output power that would be usable, stand-alone.  Most broadband high power gain blocks are limited to maybe a few watts.  The higher power modules DEMI and Q5 Signal use in the current crop of transverters are relatively narrow band.  Even the power amps in the "all-band" transceivers available today won't work very well above about 500 MHz.  100W class SSPA's are pretty cheap and could be cheaper if you add your own T/R switching, which, of course, increases the complexity.

I'm pretty sure this device would blow away any current "all band" radio in RX performance and they are targeting a $500 price point !  $500 for good performance on FIVE bands above 50 MHz, plus automatic band-switching (with the proper IF radio), referenced locked stability and built-in sequencer to run those outboard PA's.  All in one relatively little box.

I know what the inside of MY rover-mobile looks like with all those bands running through individual boxes !   This would go a long way to cleaning it up.

Yep, looks good. But this plug-and-play appliance operator would still like a single box that covers those bands and has good output power. Probably not gonna happen.

Interesting new product from Downeast Microwave.  With the addition of a few medium power amplifier bricks and a IF radio capable of 6M, this would make a really nice, compact Rover setup.
