Thanks to Wayne, Tony, and Don for their answers to my question.
I am going to use my DL-1 20-watt load and do the calibration manually and
monitor the heating of the resistors (actually, I have a nice Fluke temperature
measurement tool to do job if needed).

Anything under 2:1 will allow the TX GAIN calibration to work, but I'd shot for
< 1.5:1.

Phil,
Your 20-watt dummy load will work with the automated procedure, and it is
the best one because if the SWR is over some threshold you'll get a "SWR
too high, calibration failed" message.
The 20-watt load is very unlikely to overheat; my 10-watt load did not
overheat, because the 50-watt tran
Phil and all,
There are two types of dummy loads - one is simply to provide a load to
your transceiver or amplifier for a quick sanity check that the
transceiver or amp is providing output and is capable of transmitting a
signal.
The other type of dummy load is one used for calibration and/o
I have two dummy loads that might be useful for the 50-watt TX-gain calibration
but neither of them are dead on with a 1:1 SWR and 50 ohms resistive load.
Actually, my smaller 150 watt dummy load is closest with a range of 42 ohms on
the load to about 55 ohms on the high end as I step through t
