Haha, probably not.
Got a new aerial group to go up for 2,70 & 23, only modest, for 24/7 all weather use so the pre-amps sound ideal, just need to source one for 23cm. Was looking around wondering what to get.
You sound super productive, all those projects. Hopefully you'll get the boat in this year. Our yard has locked us out again, hopefully lifted by april?
I found a very economical German Class B AIS on ebay - bit of a last minute change as I had only planned to fit a Rx. The now unwanted rx is being used as a propagation monitor feeding the sentences into a nmeatools nmea to Wi-Fi box. Opencpn base map is good enough to show me what vhf is doing on my phone.
Same setep on the boat I can have as many "no wires" chartplotters aboard as I want, works really well and a super feature is that i can grab kap ? Charts taken from Google earth satellite images that overlay vector cmap charts - super accurate you can calibrate the commercial charts and super useful - real images of anchorages, mooring buoys in harbours, marinas etc and by a great stroke of luck, the images of the Helford river were taken at low tide so show the narrow tortuous deep channel thru the mud we have to negociate to get to/ from the boatyard every year. Clearance less that 0.3m in places so have to position the boat within a metre or so. Helps a lot but we invariably go aground anyway haha.
Happy New year Robin

Certainly! I'll build up a couple to check them .. they are more a "contest" HA8ET style LNA than a high gain EME style one. They feature a suitable "notch" on the input for 432 or 144, an output filter for 432 or 144 and a protection relay on the input to try and preserve the LNA when sitting on the end of a relay that may have QRO on the transmit port, a pot is provided on the output so you can set it for just enough gain ... they should fit the standard tinplate boxes.
Let me build them up and get back to you, I have cocked them up, you never know ;)
