ON4DPX

@uhf_satcom Half-Life! Nice! Damn i’m really that old ;-)

Testing a 3dfx graphics card with the best game! Not had a 3dfx card before, I think its missing the VGA pass through cable, will a KVM cable work ? VGA m to f.

@Dave_Cawley No its lineair, purpose now it to test if the feed illuminates the dish well. Next step would be adding a septum for L/RHCP.

@ON4DPX Is it circular L & R ?

Made a new feed for my DSN system, measured sunnoise and got a nice average of 8dB on a 90cm dish.

@Dave_Cawley I have modelled the horn for a dish with f/d 0,6, it has a direct WR90 input to match the LNA.

@ON4DPX That looks good, tell us about the horn?

@xjamesmorris Its a Skywatcher EQ6

@ON4DPX What mount is that?

Some more directional coupler fun. #rfmechanics

More mechanical RF fun, made a high power directional coupler. #rf #rfmechanics

For the love for RF mechanics !

Crowded 40m tonight !

@clockspectrum This one used to be my reference for years in all kind of antenna related stuff , very curious about Balanis .

Incredible book and is the bible for graduate level antenna theory. Consider it the warm up for the even more painful Advanced Engineering Electromagnetics also by Balanis. All joking aside, they are great books that could be studied for years.

My new reading pleasure

Some RF mechanics fun

@StaticVoyager What freq/channel ? It amazes me that they still broadcast analog.

Wow, this is the first F2 propagation I’ve seen on TV. Currently I’m receiving the RCN TV network from Colombia 🇨🇴 on channel 2 here in Ohio. That’s about 2100 miles.

Mondayafternoon job : making antenna parts . #rfmechanics

Nice signal and good music from @ManxRadio on 1368 kHz .

@JL1HID Wow this is the model we all have been waiting for ! Dual “key” function and the “metei” and “spep” will make even make DX possible under bad conditions! Thanks AI you can’t fool a old hand ham radio operator 😉

KENWOOD New Model😛

@uhf_satcom The good old days !

My old UHF, band III, and Band I tv dxing antennas from the mid/late 80s. Also at the top is a 11GHz gunn plus 10dB horn for FM tv experiments.

@otti_sat Thanks ! Indeed , wel i said non lind of sight ;-) Funny fact is that right in the middle of that pad is a small hill .

@ON4DPX Line of sight is overrated hihi :-) 10GHz bouncing around everywhere. Looks fantastic your setup.

First qso on 10Ghz , 46km distance , stereo quality non line of sight . Great experience!

@uhf_satcom I spotted this one during holidays …

UHF horizontal & Band III vertical still pointing at the Émetteur de Haute-Goulaine 15 years after the analogue service ceased!
