COAXIAL CABLE LMR400
Martin, my 3m stretch of ultraflex 13 which I use at home for rotator loop has lasted about 2 years now with no noticeable degradation, but as already mentioned it's a consumable at end of the day and

Tuning BAO board
If you want to offload one the boards Colin let me know, I wouldn't mind running two BAO amps into a hybrid combiner/splitter (I have two of these).

Thanks Colin, yes I have the original article in Microwave Projects, it doesn't make it clear if you remove one tab from the top (or bottom) of the tuning strip, and then proceed to the other end (if

Tuning BAO board
Taken delivery of original BAO amp which is working but needs output tuning. Input vswr is fine. Built one before (NTG clone) which didn't need tuning. I take it the procedure is to remove one soldere

Anyone got a spare mrf9045 or equivalent they'd like to sell for the original BAO board (I took a punt on one off eBay and it was a dud, say no more!)? Failing that I'll buy one new one, just thought

rock crushing interference on 13cm
Thanks guys, looks like I'll be parking up in my van next to local cellphone masts with patch feed+ tvtr+rsp1a and PC to confirm before sorting out some filtering! At least I won't get any funny looks

EME for beginners
The answer to this is depends on what you want to achieve. If you are looking at digital modes then yagi array and QRP will almost certainly get you QSO's with some of the 'big guns' on 23cm. Starting

socket and plug for masthead
Just wondered what sockets and plugs people are using for masthead mounted stuff containing LNA amps etc. Have some new projects to box up now, want to make a decent weatherproof job of it.

ssb electronics 23cm preamp

Where is the focal point of an LNB?
Chris, I also use a 1.8m TVRO dish for Es'Hail. I'd agree with what has been said that the focal point is not usually where cacluated. My POTY fits nicely inside a purchased LNB holder using two 22mm
