Excellent work, Iain 🙂
Excellent video, Iain 🙂 It's great to see a couple of blokes out on a day off, doing some microwave experiments. 140km on 24Gigs FM is good work! Plus in a public area, there's always the "oh what are you up to here" Nice demo of the Maxicom too!
WOW, just ordered one!
Did you adjust the variable resistors on the compressor board at all? I cannot find something useful in the manual on how to adjust it properly. And did you change any settings in the radio menu or service menu?
Great work guys! VK4UH
Would be interesting to repeat this test with current equipment
Well done, Iain 🙂
OMG jumping out of a perfectly serviceable aircraft 😮😂
Not perfectly servicable. Note the gaffer tape round the window about 40 seconds in. 🤣
great demo!
Great video guys. Maybe would benefit from some commentary or explanation ?
Wonder why Yaesu doesn't just build this circuitry into the radio? Surely they know how crappy it is without it.
More DSP = more battery drain
Do you remember when you were allowed to be in a room with that many people?
Great vid... Sad about the volume of music, would have been good to hear more of the OM's haggling and talking! Thanks 5AKR and 5PW, I'm only sorry that I didn't attend myself. Ah well, hopefully next time... Cheers guys and 73. de 5FX
Nice...
🙏🙏 awesome 73 de vu3mes
Great demonstration
Well done! de VK4WS.
I had a audio booster installed in the FT-817 stock mic a while back.. Will the DYC-8X7 work better or is it overkill?
Without knowing what the 'booster' is doing I can't say.
Interesting subject, but the audio is quite difficult to understand. Will have to try with headphones.
Nice video, especially demonstrating the LO phase
Thanks very interesting 73 Gary vk2kyp
Nice video Iain. Neat portable setup and a lot of thought has been put into it!
Hello. The CHA 250 is a great device, but the CHA 250 F with the RG100 feeder instead of a winding ordinary wire is a real firecracker. More on QRZcom / HF7ST. I am sorry to be here but I do not have an e-mail contact. Small field, great happiness - Ham Radio! Tnx QSO.GL, 73! Adam HF7ST
Cool stuff. Way to go. 73s!
great stuff, congrat`s , so bad as we do not have so much water available in OE, 73 de Wolfgang OE4WOG
Was this contact FM? What was the power?
Yes, FM. My TX power is about 250uW (-6dbm).
Very nice. My first microwave contact was 110km on 10GHz with 250mW on SSB. You're running 1/1000th the power and on FM. Not to mention at 5 times the frequency. Impressive :)
That looked like a cyclone
Yes
beautiful QSO, congratulations,Mircea,YO5AXB.
ecellent Video cutting and editing, tnx to Ian, VK5ZD for making such videos available ..73 de Wolfgang, OE4WOG
fun and enjoyed. Hope you make more ham radio videos thank. !
good job guys, see you in Friedrichshafen soon, :-) 73 de Wolfgang, OE4WOG
