Old Motorola HTs as MURS radios

[W1PML]

I have a handful of VHF Motorola HT600 and P100 HTs. My understanding of the rules is that these models were certified for BOTH Part 95 and Part 90 back in the day, so they are grandfathered. Some of the HTs are the 2 watt versions, so it seems pretty clear to me that I can legally use them on 154.57 and 154.6 MHz. However, I have a couple of P100s that have the "Hi/Low" power switch. If I modify the radios to operate only in the low power mode, say by removing the switch and soldering, would these radios be legal on MURS?

Only if they have been re-certified by the FCC after the switch modification. This same argument went around going from wide to narrow band. The FCC made several announcements to the effect that if the radio wasn't originally certified for narrow band installing a narrow band kit required that the radio had to be re-certified by the FCC. Proceed at your own caution.

Thanks BB.

I suspect that it is not legal to use the radio solely in low power mode, for the same reason?

That is correct ... however in the real world people tend to do what ever works. A example of this is our local county court house maintenance crew uses Motorola ht1250's on MURS ch.5 with a Dpl 114 so this is legal? No, but then I digress... :roll: 73, n9zas
