[amsat-bb] Any experience with low-cost 433MHz transverter from transverters-store?

I don't have any experience with that transverter board,
or with transverters generally. If you can get the 70cm
board to operate at 435-438 MHz, it could be useful for
satellite work even at 3 to 4 watts. I regularly work
the SSB transponders with a 5W FT-817ND as part of my
portable station. If you could get that transverter up
toward 4W, it could work as an alternative to a radio
like an FT-817ND.

For my portable work, I use short coax runs - 10 feet
between antenna (Elk 2m/70cm log periodic) and a 2m/70cm
diplexer, and 3-foot runs from the band ports on the
diplexer to my transmitter and receiver. Longer coax
runs may not be the best for that 3-4W output, and
could also require the use of a preamplifier on receive.
