You can operate your base HF rig (the 7200) and the VHF rig from the same power supply. You just can't
transmit on both at the same time, but you can monitor on one, transmit on the other.
For a power supply I can highly recommend any of three models, the Samlex SEC-1223, SEC-1223BBM, or SEC-1235M.
The SEC-1223 is a 23 amp supply that will give reliable power for a 100 w HF SSB rig, or 75 w VHF FM rig. It can also power
a number of accessories, meter light, tuner, etc. It is rated 23 A continuous, 25 A surge.
The SEC-1223BBM is the similar as above, but about 2" longer to accommodate a "Battery Backup Module", which when
connected to a 12 v battery will provide backup power when the lights go out. If 120 vac fails, the SEC-1223BBM will instantly
switch to battery. This is so fast, so smooth, the radio will not even blink. Seamless operation. When power is restored,
the supply will switch back to 120 vac power, and at the same time charge the 12 v battery. Once fully charged it will maintain
a "float charge" to keep the battery topped off. Otherwise, same power output as the SEC-1223.
The SEC-1235M is similar to the 1223 but instead of 23 A / 25 A like the 1223, it is rated 30 A continuous / 35 A surge. Also
it has Volt and Current meters on front.
All three of these supplies are small, light, run cool, and do not produce any of the dreaded RF hash that some other switching
supplies produce.
Another accessory you need for the IC-7200 is a tuner. I can highly recommend the LDG IT-100 tuner. I've had several of these
including one in my HF portable / emergency kit now. I have another with a 7200 at our club station.
The radio and tuner can be set to "tune on PTT", that is, as soon as you key the mic, if the system needs tuning, SWR higher
than 1.7:1, it will automatically go into tuning mode, reducing the IC-7200's power to 10 watts and producing a carrier wave for
tuning. When tuned, SWR is down to 1.3 or less, it will stop and return the radio to its previous power and mode setting. It is
not going to tune every time you press the mic's PTT button, but only if it senses it needs to tune, such as after a band change,
or a frequency change over a certain amount for where last tuned. Take advantage of this. It will only tune on PTT when it needs
to.
