.... 432 MHz EME anyone?
I'm in. With Gerhard, that would make three, enough for an intercontinental round table ...

I have an FT-847 sitting in a box here at the office, that is not being used for anything. I'll need a longish lead time, though, for the antennas, etc.

I gave away / sold all my 4XC250 stuff, although I did find some Johnson silver sockets, and some 4X150's when I was scouring the shack for a prefab FM tuner a couple of summers ago.

Considering all the drama over just a simple HF rig, which is still nowhere close to being finished, maybe giving away the VHF / UHF parts was for the best ...

I have found that stuff in the basement this week:
One Coax socket
3 pcs. TH316 tubes, boxes still unopened (all but one, I was curious)
I have no idea what the spark gap is for.

The used coffee mug happened to be still on the table from
earlier this day; it is on-topic by pure co-incidence.

A friend of mine is really active; with his new antenna, 10W
and a 4 element should be enough for 2way qso.

Wow. That array should be on magazine covers.

Yeah, 1500 watts into that array could push the moon out of orbit!

The antenna array has 33.6 dB gain over a dipole and a dipole is 2.1 dBi, so the array has 35.7 dBi. Feed that 1500 watts and you have 5.57 MEGAWATTS of ERP. The maximum ERP allowed for TV broadcasting in the USA is 1 megawatt.
