Jeremy - if you look closely at 95.135 is says that no station shall transmit with an RF output power of more than 50 watts.

 

That is NOT ERP, but the raw RF coming out of the connector at the back of a repeater or a moble type radio.  The Commission couldn't care less about ANTENNA GAIN and ERP for a repeater or mobile type radio.  One of the systems I use each occasionally each year has a 50 watt output from the repeater into 175 feet of Andrew hardline to a stacked vertical array with 11.9 dbd gain... which is just under 600 watts taking line loss into consideration. That system is on an elevation 210 feet above average terrain and the tower is another 168 feet. It has a service diameter of over 100 miles.

The challege with Wouxun and Beofang radios might be the odd bandwidth for MURS. MURS uses 11.25 and 20 kHz. Most radio service in the same region (2m) is 12.5 or 25 kHz. Has anyone tested one of these radios with a MURS specific radio listening? What does it sound like? I am curious how it sounds when a radio is transmitting slightly over the bandwidth allowance.

I so far don't see any mention of the Motorola GP300 vhf's, I have 3 myself programmed for the MURS band and they work great

around here. But I'm in a quite spot  in northern Illinois.

Eagle Base. :D

Ron - Thanks for the reminder on the Motorola equipment. :)

 

Anyone else using these?

I have the two wide band freqs in a Motorola Systems Saber on low power.  I also have National Weather and some of the local two meter stuff in it.

 

Every now and then on E-bay you can find low powered (H33 series) two channel Motorola HT600s or P200s

I am in Northern Maine, where the logging trucks all use the MURS frequencies. Each road maintained by the Maine North Woods has signage which directs you which MURS channel to use. "4 wheelers" or road users such as myself are required to announce their location as a matter of safety. I was seeking a good quality MURS handheld for this purpose; I've ordered the Ritron PT 150M which operates exclusively on the MURS channels. It looks like a good solid unit and I like that it is American made. I am waiting for it to arrive, does anyone have experience with this model?

I personally have had good results with my Motorola gp 350 and 300 vhf series radios,

no experience with Ritron.

I'm sure that the Riton users will get to your question soon.

 

In the mean time, Joseph, welcome to the forum.

M/ACOM Panther 605m mobiles fall into this group, they are high low power computer programmable

for 5 watt low and 20 watt high power. I program each individual channel twice for close and long

distance mobile use with the Harris software I bought. TAIT 2020 is the same radio and its software is

just for that radio. I have both the uhf and vhf models of the 605m and they both work great.

Anyone here have experience with the Motorola RDM2080D series MURS dedicated radios recently?  Looks a little pricey as compared to some...

Nearly all of the Ritron VHF radios are MURS accepted. Even their little intercoms are type accepted for Part 95A and Part 95D operations (as well as Part 90). 

 

The Motorola VX series are pre-programmed with MURS frequencies as some of the channels.

 

Motorola RDM series as well.

 

GMRS ERP is never listed. Just transmit power. The 675 system in Lubbock, it runs 50W right out of the transmitter, looses about 1/2 dB going through the duplexer and then goes up to the tower mast about 80 ft in 1-1/4" hard line to a DB420 that is mounted roughly 360 ft up. ERP through that (including line loss and loss through the duplexer) is around 615W...if only we had put a DB413 up there instead. It only talks for about 40 miles (due to the fact it's perfectly flat up here).

 

Path loss is just about insane to begin with. Low band, high band, UHF...higher frequencies means more practical gain antennas. Remember, NASA sent video nearly a quarter million miles from the moon using about 1.7W (UHF).

Ritron is the only company that I know of that applies for 95A acceptance from the get go.

Kenwood. Most UHF analog Kenwood gear is 90/95A. 2 out of 3 of their current analog UHF mobiles are 90/95A.

I didn't do much research, but thought I would ask aloud, with the MURS rules for 2 watts, I wonder how many licensed and non licensed radios are being used on .570 and .600 at wideband and 5 watts simply because they were grandfathered on the freqs.
