is it possible to use a hackrf one for WB Datv i already have NB tx im wondering if its possible to use the same kit..??

The only way I can think of you using it is with GNURadio as that supports both DVB-S2 and the hackrf.
You could always write your own code I suppose.
No I won't be adding it to Express although people do ask.
It was really designed as a hackers toy (for intercepting keyfobs and the like) and I have a feeling that
it's RF ouput may not be that clean.

thanks charles

altho i have dropped the hackrf one and now using a pluto. just waiting for the txco mod to arrive from germany now to make it stable..

The HackRF was ground breaking it it's day. It seemed to have a bigger backing in the infosec / hacker community than it did in the Ham one.

Glad I got my Pluto before the fall in the pound and the Analog devices end of the student discount.

I have not done the TCXO mod on mine but as my new project will require the extra stability I may well do it.
I think Colin G4KLB has been trying out different TCXOs.

for tx on eshail sat the txco is a absolute must... the pluto drifts really badly without it..

my hackrf one that im now selling on good old ebay does infact have the txco 0.5ppm installed

as soon as the txco for the pluto arrives from germany it will be installed

I believe that is the same part as

Which are £3.08 each.

I just need to find some other goodies to buy to get the value up for free shipping

I need one of those TCXOs too - unfortunately they were not in stock for my last order so I have got a voltage tunable one which was in stock. That's OK but the tuning voltage needs extra parts and potentially extra drift and noise if you use the Vcc pin for that. Trimming of the offset is not required for the Pluto as it can be done in the software. The tuning pin can be connected to ground, but than the frequency is off more than it should be. Definitely don't leave the tuning pin floating.
