Those were fun days Clare!
My most challenging contacts were made using K band (24 GHz down). First contact was on 4/20/2002 with Jerry, K5OE.

I think the only mode I never got to try was 2.4 GHz up. I have the transverter sitting here in my shack, but AO-40 went bang before I got to use it. The plan was S/k.

Hi Mike, N1JEZ
You should remember that you and I and Charles G3WDG we partecipated to the only one test made on 2.4 GHz up and 24 GHz down i.e. mode S1/K on AO40 on day 02/23/2003 and I was received on 24 GHz both by you and by G3WDG.
I still have your CD diskette made by you and sent to me with the record of my 24 GHz signal received by you in Burlington VT
Unfortunately at that time I was not ready to receive on 24 GHz but I was only able to transmit on 2.4 GHz with 10 watt at a 4 feet prime focus dish.
Unfortunately for that experiment scheduled by AMSAT and command station Stacey Mills W4SM only three stations where active i.e G3WDG, N1JEZ and my self ,i8CVS
G3DWG was equipped to transmit on 2.4 GHz and to receive on 24 GHz so that only he was able to get back his own signal from the transponder.
You where only able to receive on 24 GHz but not to transmit on 2.4 GHz so that you where able only to copy G3WDG and i8CVS on 24 GHz
I was able only to transmit on 2.4 GHz but not to receive on 24 GHz so that at the end of the experiment no two way QSO S1/K was possible to made between us but most important the experiment demonstrated that the S1 2.4 GHz receiver on board of AO40 was working and was alive and well !
Those were really fun days Mike !
