@scott23192 Yeah, better not reach too far just yet... So what made you select the 1m dish over the other somewhat larger models?

[Red Willoughby @KC4LE]

@scott23192 And the dish & LNB - what are those products? I’ve got to get on microwave!

[Red Willoughby @KC4LE]

@scott23192 I see that the 1m dish can go to 11GHz with the 2.8 mm mesh hole size. And that particular Kuhne downconverter is for S-band. So how do you switch to receive C-band & X-band?

[Red Willoughby @KC4LE]

@scott23192 I built that same dish feed, inspired from your experimentation with helicals a couple of years ago. What are you using for an LNB?

@ARISS_Intl @scott23192 Listen for W3ZM/8, AMSAT’s call sign, this Friday & Saturday from Hamvention at Xenia, OH. AMSAT members will be demonstrating FM & SSB QSOs both days. Not sure if APRS mode will be part of the demos.

@scott23192 Very inspiring post, Scott!

@scott23192 Maybe there is a WebSDR in EU…

BOTAN内部のAPRS送受信ログです。多くの方に使っていただけてます。近いうちに海外でも使えるようにしていきます。
あと、やはりISSと衛星間通信してますね！

@scott23192 Is that a passenger transmitting RF from the cabin? Or is it something akin to airplane scatter?

@scott23192 @K0FFY_Radio @n6rfm The calc says ~18” pizza pan is needed for a 420 MHz ant. The photos of Scott’s & Bob’s antennas look like they settled for a medium pie (12”) instead of a large (18”). Based on the positive performance reports, this must not be a critical parameter. Is this observation correct?

[Red Willoughby @KC4LE]

@scott23192 @K0FFY_Radio @n6rfm What did you use to wind the coils on? It needs to be about 9” in diameter.

[Red Willoughby @KC4LE]

@n6rfm @K0FFY_Radio @scott23192 Bob, is that for 436 MHz?

[Red Willoughby @KC4LE]

@scott23192 I am also chomping to get a dish antenna outside to experiment in the microwave bands!

[Red Willoughby @KC4LE]

@scott23192 I love that thing! You might remember that I twisted-up a couple of those units about a year ago after we discussed parameters. I’m in an antenna-difficult QTH, but I can throw one of those out in the clear and see how it does.

[Red Willoughby @KC4LE]

@scott23192 @SatNOGS LOL!!!

[Red Willoughby @KC4LE]

@scott23192 @AmsatSpain Thanks for those configuration snapshots

[Red Willoughby @KC4LE]

@m6sig @scott23192 Before transmitting to the transponder, just disconnect the antenna from the SDR that is collecting telemetry.
