Be wary of using the 746 with transverters as ALL power levels regardless of
band are set by the front panel power pot.
Easy to forget in the heat of the contest while rover.
I was a very active and competitive Rover for over 20 years and if you would
like to ask questions off the group feel free.

Sean - The IC-746 is a good rig for roving. You will do well with it. You may
want to try it out in the CQ WW VHF contest, which only has only 6M and 2M.
For the ARRL contests with more bands, you will do well with the 222MHz FM.
People can still work you and the multi is desirable.
You asked Dean about power handling. I use a deep cycle battery in the car. I
charge it directly from the car battery through a ISOpwr. The ISOpwr charges
the deep cycle battery whenever the car battery is at 13.5V or greater, and
disconnects itself when the car battery voltage falls below 12.7V. This
effectively charges the deep cycle battery whenever the car is running and
disconnects when it is not, thereby keeping the car battery charged. I also use
a W9XJK boost regulator to maintain the voltage at the radio at 13.8V so that
as the deep cycle battery voltage drops, the voltage to the radio remains the
same. This is an effective system and requires little thought to keep running.
The hardest part is running a wire from the car battery into the passenger
compartment, but that can be done with some patience and perseverance. I use
Anderson PowerPoles and they make hooking up DC power connections
straightforward and mistake free.
The 746 has three antenna outputs, one for 6, one for 2, and one for HF. Use
the HF one for a transverter. I am not sure if the power out can be set by
independently band, if it can you don’t need to worry too much about blowing up
the transverter, if it can’t you can put an attenuator between the 746 and the
transverter and if you forget to turn down the transceiver, all you will do is
blow the attenuator. Carry an extra attenuator. DEMI makes such a device
commercially.
Make contact with the big contest stations and ask them for suggestions as to
which grids are they would like you to operate from.
Don’t try to bite off too much at first. Concentrate on getting a few bands up
and running and then add bands. I think choosing locations and a route the most
important part of roving, followed by power management and then antennas and
their mounting. With that in hand you can use pretty much any rig, identify
what you like and dislike about it and then concentrate on that.
Also operating style is important. Be quick and precise. Use phonetics. QSY
stations when you work them. QSY with stations when they ask you to. Use
headphones, preferably a headset with a foot switch for PTT. If there is
nothing to work on phone, try CW, and vice versa. If there is nothing to work
on 6M, try 2M. Avoid hogging the calling frequencies. Use computer logging with
the computer interfaced to the rig if possible. A K1EL Winkeyer is good to have
for CW.
Color coding things by band is a good way to keep things straight. You will end
up with a lot of wires and cables to hook up and it is easy to mix things up.
Color coding makes keeping track of things easier. You can buy a pack of
various colored electrical tape at most hardware stores.
After dark, a headlamp is nice to have. A compass is good to have for finding
bearings. Keep spare hardware, nuts, bolts and washers. A small tool kit is
useful. Trying to minimize different sized hardware is useful.
You will need to come up with a good answer to “What is that thing?” Listen for
the weak ones. - Duffey KK6MC
