[TenTec] Model 1225 SWR and Wattmeter Kit

[Jim Allen]

Compact HF/VHF SWR/Wattmeter. Has huge 3" Cross-needle meter. Read
forward/reflected power and SWR simultaneously. Perfect for mobile or
portable operation. Two selectable power ranges, built-in meter light (+12
VDC). SO-239 Connectors. 3 1/4 W x 3 1/4 H x 3 1/4 D inches.

MFJ-822 covers 1.8-200 MHz, 30 or 300 Watts.


It's about $60 or so.  I've had one in use for a decade or so.  I doubt it
is as accurate as a Bird wattmeter, but it seems reliable enough for use,
as long as you don't need to run power.  This one has two ranges 30 watts
and 300.
