DVB-T SDR Question with Pluto

[G1BVI]

I tested my Knuckler/Ryde with my PD4/LimeUSB transmitting DVB-T without issue.
I tested the Knuckler/Ryde with an off the shelf Pluto transmitting DVNB-T without issue.
This combination also works as an FM/J3E TX/RX .

However When using a Pluto flashed with the F5OEO and patch as per ZR6TG's web site it will not transmit DVB-T that I can resolve nor does FM /SSB work properly.

Am I right in assuming that the F5OEO firmware and patch is only designed to work on DVB-S
If I downgrade the Pluto to the reccomended 0.31-4 will it

1 still work as a DVB-T TX
2 Will it work as a DVB-S TX for QO100 operation.


Thanks all

I'm also struggling with transmitting DVB-T from a Pluto and being able to decode the signal with a known working HiDes receiver. I'm not sure if my issue is the same as the one mentioned here, but I also have the F5OEO firmware so I'm wondering if I should roll the firmware back and try again.

I'm also wondering if anyone has the answer to G1BVI's questions?

Thanks,

Is that at 300ks/s or 2ms/s?

Make sure you have read the threads on powering the Pluto as it seems more critical with DVB-T. I assume this is with 0303 Firmware?

It has been a long time since we experimented with DVB-T as it was found not to work as well as DVB-S/S2 in most cases and amplifiers tend to produce less power with acceptable quality. I think the last time I used it was for testing the NEC 70cm amplifier pallets we obtained a few years ago.

I don't know how many times I need to say this:

THE PORTSDOWN SOFTWARE IS ONLY DESIGNED TO BE USED WITH A PLUTO LOADED WITH v0.31-4-g9ceb-dirty FIRMWARE

Please don't complain if it does not work with any of the many other Pluto firmware versions available. It just winds me up!

Sorry Dave,

I forgot to mention that. I hadn't twigged this was with a Portsdown.

Have any more of those excelent 70cm pallets ever come to light
Is there a particular DVB-T txer I should be looking out for?
