The r1225 is still not a 100% duty cycle machine. They have a week spot at full power? the solder melts on the final and causes a failure we have on in service but cut back to 20 watts.
True, but I have had success at running them at 22 watts.? have a couple of them here that I use for backup replacement repeaters while doing repairs. The last time I used it was on a VHF ham repeater that has a weekly net that sometimes runs 30-40 minutes. The R1225 survived well, but the fan MUST be running. I have another VHF one on the air at a club repeater site for a couple of years now. The old Spectrum Communications SCR-77 repeater at this site finally gave up the ghost.
The R1225 repeater is definitely not my first choice as a full-time repeater, but they do work if you keep them in a reasonably heat friendly environment. Not a good choice for a heavily populated commercial site.
