Thanks Conrad - I had read that before but this antenna is different. It is LHCP on S-band and has a different lens on the front. -- Mike G0MJW

Hello Mike this thread contains information as to where you can read in more detail. https://forum.amsat-dl.org/index.php?thread/28-es-hail-2-transverter/ 73 Conrad PA5Y

Looks nice. Any details on the design? -- Mike G0MJW

Yep, that seems to give values that look reasonable, TNX. I'll give it a go Andy www.g4jnt.com

Hello Andy You can try:- https://www.changpuak.ch/electronics/combline_bandpass_filter_designer.php It’s pretty simple – and comes with the caveat that I have not used it ! However

Hi again Gordon, Just realised I left a bit off the end of the code when copying and pasing it Here it is

Can anyone point me at a standalone bit of software for combline filter design. I have Ansoft Designer, that Paul Wade recommends for this purpose, but it's a bit over complicated and was looking

Hi Gordon, I have been using an ADF4351 t generate 27 MHz for an octagon. I am programming it with a Arduino Pro-Mini. I copy the the "sketch" below if that is useful. Also I recently bought another

Hi all There appears to be several variations ofthe Octagon with OQLG going for £ 13 and OQSLG going for £18 There also references to Multi Switch HQ and HDTV I assume the

The EAN number looks ok, so it is PLL Van: "g0ruz" <g0ruz@...> Aan: "UKMicrowaves" <UKMicrowaves@groups.io> Verzonden: Donderdag 24 januari 2019 13:50:30 Onderwerp: Re: [UKMicrowaves] Single Octagon

The Chinese boards with non-fake 4351s are still not brilliant, I have four or five of SV1AFN's 4351s which I've used with Arduinos and PICs. Neil G4DBN

You can search for Inverto or Goobay LNB's too, they have also PLL. It looks like Octagon's have unknown delivery date... Jerry Van: "g0ruz" <g0ruz@...> Aan: "UKMicrowaves"

Yes, this is correct Regards Matthias Von: UKMicrowaves@groups.io <UKMicrowaves@groups.io>Im Auftrag von Conrad, PA5Y Gesendet: Donnerstag, 24. Januar 2019 13:51 An: UKMicrowaves

Yes. I demonstrated one at The Scottish Microwave Round Table 3 years ago. The third harmonic was audible on 10 GHz. Not sure of current sources. I have the code somewhere. Busy today

As I am obviously quite stupid can someone confirm that this is correct? https://www.ebay.co.uk/itm/Octagon-Optima-OTLSO-PLL-Twin-Slim-LNB-0-1-dB-FullHD-HDTV-Digital-2-Teilnehmer/160906911008? This
