I have a couple of VHF Quantar receivers and just curious on other than changing the receiver, that I can buy on MOL, what else is required? Does the controller board need a re-flash for the new frequency?
Thanks

Just reprogram it.
Ok, Couple of other things besides the pre selector.
For example, A UHF R2 quantro will drop dead in the RX department at about 480.900, and will stop transmitting around 478.000.
You will need to change the RX'r to go higher into the T-Band, and the exciter will need to go for anyhting higher in the T-Band.
The power amplifier from the quantro (same as the MSF) is slightly more forgiving. We did testing and noticed no considerable performance loss up to 481 TX. This also included the circulators, which we removed and tested independantly.
Now, as far as the qunatar with the smaller cage mounted amplifier, I don't know if it is as forgiving as the MSF amp.
Now, as far as the VHF equipment, I am not sure, never had one. But my round about point is like posted earlier, try to push it as high/low as you need it to go and check the performance specs. If the loss of RX sens is acceptable, and maybe can be made up with a pre amp, you saved yourself a boat load of money.
If memory serves, The new from MOTO RX'r and exciter were about $1,800.00. The control card is universal for all of the units even bands. There is an initial set-up screen that you can select the split, power, circulators, etc.

P.S. Mileage may vary from unit to unit.
