MY QO100 SETUP

Hi, another 1600 FreeDV image dump.
-
Hi, much better now at full power ...

Hi, the next subproject is to operate the FM talkback channel at WB. A switch to the reprogrammed Attiny13A is only needed.
By the way a 1.4 m dish is found and I have a promise for an amplifier 2.2 GHz from 3G to operate DTV (Pluto exists).
-
Hi, anyone to try FM talkback channel ?
-
Hi George,
this is not official... it was an proposal/experiment by BATC ..
The proposal didn't really work, the chat in WebSDR is still the better variant. Or why not Duplex RB-DATV?
After recent experiences with FM stations overpowering the WB, our acceptance has declined. The proposal will not be pursued further. That's also why it will not be in the official bandplan.

Shortest reply I read here on the forum. Congrats George! : -)

It would be useful for those without WB mode TX capability, but we could do it on SSB via the NB transponder, just define where you are listening
-
Hi, any experience with this spectrum analyzer with tracking link ?
I have one and it works surprisingly well, even better if you do the mods detailed here http://alloza.eu/david/WordPress3/
The F4HTQ SNASharp Software works well with it after flashing the new firmware. Good value for money but with the version 2 of the nanoVNA soon to arrive it may be worth waiting.

Hi, a experimental 430 Mhz filter using a eBay tin box 11*7*4 cm . It has 30 MHz 3 dB BW, loss 3 dB.
-
Hi, updated block diagram.
-
Hi, anyone know how much power is this circulator ?
-
Hi, optimized IMD block diagram.
-
Hi, 6 dB attenuator.
-
SV1BDS B.t.w. I received the CETC CTI OSC5A2B02 10 MHz OCXO today. Will take a little time to test it because I have too much projects to finish (like doubling the shelf surface with MDF in my shoe cabinet ; -)
Hi Remco, any news about both projects ?
-
Hi George, no .. no news ; -) Busy here with other 'non RF/electronic' stuff but after that this OCXO and minimalistic transverter are next in the project queue.
