I still need a PA! I could build one but I don’t know of any modern designs and PC boards for 2.4GHz amps in excess of 100W, even then I don’t have a power meter for setting up. Does anyone know of a commercial source of such amplifiers please or can offer any other suggestions? My DATV TX has otherwise been ready to go for 8 weeks so extreme frustration here!

Your experience is not very different from mine having ordered a 90w 13cm PA from Bert PE1RKI in March this year. It finally arrived last week following two chase emails, some 15 weeks after ordering. I think that the suppliers of these 13cm PAs have been overwhelmed by the demand created by QO-100. I'll probably do a review for CQ-TV when I've got it housed and heatsinked.
To be fair to Bert, he is not running his operation as a business and like other amateurs he does have a life outside amateur radio which sometimes gets in the way of the hobby; he had apparently some renovation work going on at his home which didn't help.
However, DFE has a much wider range and comparatively higher prices so I would expect a better service than you have received from them.
If you do get your money refunded have a look at PE1RKI.com although you'll inevitably go to the back of the queue again!

Believe it or not the amplifier actually arrived today !!! talk about coincidence. Anyway I'm in the middle of installing it now so hope to be on in a couple of days. Thanks again for your reply which may also be useful to others.
