[nrv-hams] Possible HF setup

[Cam Coble]

Josh,
Sounds like a plan. I'm sure you can get some good advice from others, but
here are a few of my comments:
- Great solid radio
- Power supply should be good to about 30 watts or so. If you don't have a
meter on it, just keep a voltmeter on it to watch for big drops. Then
you'll know when you're pushing it.
- The MFJ antenna is really made for the yaesu ft-817 as a compromise
antenna, and I've not heard much success. Also limits you to 25 watts, and
you'll need some ground radials to make it half work.
- I would recommend a manual tuner with dual indicators. Any antenna you
run will require some kind of tuning although the MFJ listed is tuned by
making the element longer or shorter. The tuner will be able to validate
your watts out, and whether or not your antenna is matching well. A few
models to check out would be the MFJ-971, and MFJ-941E.
- If you have a wall not pointing at a neighbor, this may be something to
look into (needs a tuner): http://www.k2zs.com/indoor-hf-antennas
- I would try a dipole strung up on the walls first. 20 meters is a great
band and you need 16’ 5” or 197” linear feet per side. You can wrap it
around the wall near the ceiling and probably do just fine. You may even
get away with not needing a tuner if you can cut to length the ends after
install. Yes, it's one band, but it will be one band that works, and you
can make it for under $20. Use some 18 gauge speaker wire and you only have
to cut once, and rip apart!
- Another good wire antenna for this application may be an
end-fed-half-wave. You can build it yourself for cheap, but here is a nice
kit for QRP: https://qrpguys.com/qrpguys-end-fed-wire-antenna


Hope that helps!
73!
