I bought 3 low band units surplus and they were all 2K from the surplus. I immediately updated to 8K 128 mode. but still have original firmware.? I have several other radios from another ham and suspect they are 8K upgrades. So a bit of a mix depending upon if you buy surplus or from ham.? the control heads are another issue. Some are difficult to bump to 8K thus limiting them. I think having both options is a benefit. my use will be mobile and base, but not remote base control.?
