[VHFcontesting] Time for a Portable rig upgrade

For 50 MHz I've enjoyed using my IC7300 while roving.   The band scope is nice and only covering one VHF band isn't that much of a issue for me.  (I find having a radio on 50 MHz all the time helps capitalize of brief band openings.)

I looked at the K3 and the Kenwood TS590sg but felt the IC7300 with the built in band scope was a better fit for my needs.

I am also curious about the FT991 as I'm starting to think about refreshing my 144 and 432 MHz roving radios.  I typically use a pair of Icom 706MkiiG's while roving. The remote control heads are a nice feature in my view.   I've tried a few other radios over the years but keep going back to the Icom 706MkiiG's for the rover.   Still at some point I expect I will need to upgrade.  Although I run a transverter on 222 in the rover I'd prefer to use pre packaged radios for 144 and 432 MHz.

For 222 and 902, I used another Arduino with software Andy wrote that watches the CI/V port on the IC9100. When I go to 26 or 27 MHz, the 222 transverter connected to Ant1 is select (my IF comes out 26=222 which also gives 223.5=27.5). When I go to 28 or 29 MHz, Ant 2 is select and it goes to a DEMI 902 transverter (28=902 and 29=903). The Arduino shield I designed has 20 turn pots for setting the ALC voltage to limit the power on these bands to drive the transverters properly. So with one radio and two transverters you cover the bottom 6 VHF bands. Yes, it's a bit more expensive but FT991A's are still new and I paid not much for the for IC9100 with 1296!
