Questions about Radius SM120
Posted: Tue Jan 27, 2004 9:16 pm
Hi,
I was wondering what were the normal operating temperatures of an SM120 UHF at 10 and 25 watts with heavy duty usage?
When used for long conversations (+/- 1-2 mins TX, 2 mins RX cycle) I noticed it gets hot after a few minutes so I installed a CPU fan to cool off the final.
Also, using RSS v4 and v5 I was able to program the frequencies in and operate the unit very well but unable to access the squelch and deviation settings as "model definition file not found" keeps appearing before I can enter the F2 - Service menu.
I've been a radio enthousiast for years but just recently started collecting M gear and information so please bare with me.
From my knowledge usually heat = high SWR but everything seems to be working fine.
Thanks,
Mike
