Routes to 6M DATV

[radiogareth]

OK, in eager (?) anticipation of Septembers activity days, how are people producing (or planning to produce) DATV on 6m?
Been playing around tonight with Portsdown 2019 and my LimeUSB. It produces a carrier on 6, but no DATV.
EXpressDVB might well oblige with the Lime USB. SDRPlay RSP1 under SDRAngel or DVBS-GUI might cover the RX. Got a 4 Element LFA all ready. Just need a PA....wonder if the 4m brick has any gain there?

My 4m PA uses the Mitsubishi 66-88Mhz brick and it works fine at 51MHz with no reduction in usable power.

Thanks, handy to know. What are you exciting it with?

Yes they do

I use both the RA07H0608 and the RA30H0608 on both 6m and 4m DATV. The one vital thing needed if choosing this route is a 6m LPF on the output of both these bricks as they dont have much loss at 100MHz. I use external QRO filters (normally used on other amplifiers elsewhere) from a design in an old arrl manual http://g4fre.com/2mlpf.pdf

I got the idea of using the RA30H0608 on 6m when i discovered that elecraft used it in their XV50 6m transverter

Sorry it was getting a bit late. I'm using the Portsdown and LimeSDR Mini. No idea why it works and yours doesn't.
