The FCC dropped the class designations decades ago. They are called Radio Services now and each Radio Service is governed by specific sub parts with in Part 95, Personal Radio Services, such as Subpart B, Family Radio Service; Subpart D, CB Radio Service; Subpart E, General Mobile Radio Service; and Subpart J, Multi-Use Radio Service; etc.

What antenna are you trying to use. The newer Silverados body materials do not have much metal in them. If you trying to use a mag-mount for a CB Firestik antenna, forget it it won't work. A K40 with the heavy duty mag-mount base will work great. If you are trying to use a mag-mount for a GMRS antenna, the Midland or Laird Mag-mounts will work great. The Midlands have the rubber boots and Laird do not. Try using some Expel Paint Protection Film in the spot where you're go8ng to place the antenna. The film will keep the mag-mount from sliding and not cloud the paint if moisture gets between the two surfaces. I'm using the protection film on my Silverado and Porsche without any problems

Become a member of the Arizona GMRS Repeater Club at az.gmrs.org. Besides having access to their linked repeaters, the Club has Ambassadors that help new members with their radio equipment and programming needs.

Saddleback was never referred to as Saddleback Peak. Saddleback is a Mountain and Santiago Peak is a Peak within the Saddleback Mountain known as "Old Saddleback" within the Santa Ana Mountains. Saddleback Mountain has two Peaks, Santiago and Mojeska. Old Saddleback gots it's name from the profile of the Crestline between the two peaks as you look from a distance and it resembled a saddle.

Phelps-Dodge is/was a quality brand product. I wouldn't throw it away. I would returned it and use it.

During those situations, you'll have more important things to worry about than trying to communicate with someone several states away. Why would your communication contact with someone several states be more important than an immediate local public safety needs? Stay off the airwaves unless you need to report or seek emergencies services if a person's life is in peril. Don't think about your selfish self, think of others that may have a more dire need.

That was kinda my guess too especially since the chart he displayed showed the correct freq. 159.190 Megs is not even a FCC allocated freq. Anyways, with all the 151/159 Meg freq pair combos the 159 Meg freq is the repeater input and the 151 Meg freq is the repeater output for CDF/CalFire.

CDF provides fire protection for El Dorado County. You listed that you programmed 159.19 Megs and that is an incorrect freq. You need to program 151.19 Megs for the repeater output freq and the mobile decode/Rx PL Tone is 146.2 Hz

And use 12 Ga. Cable with a 15 amp fuse.

Cheap Chinese junk doesn't have nearly the features and reliability factor and an accessory support and customer service and repair centers like the Motorola and Kenwood. If you want to buy cheap junk from Amazon I don't care.

Oops, I meant to say 8 something amps and not watts for the power draw.

Like I posted earlier, my MXT500 is at full advertised RF Output power. What was the input power level to the radio measured at? It should be at 13.7 volts when keyed and with at least 7-8 amps sustained.

The difference between your 38 watts and 50 watts is barely a dB which is not significant enough to make any difference in the farz and if there is any difference it may be just a few inches in better farz, ok maybe a yard or two better but you won't be able to tell the difference anyways. 10 or 11 watts more is just all mental.

I'm curious, by any chance, did you test the Midland MXT500 radio with a quality in-line watt meter like a certified Bird or service monitor with a dummy load, or did you use a cheap $100 watt meter from Amazon with the radio connected to a poorly tuned antenna that is reflecting power with a POS coaxial cable and cheap connectors? I was getting something like 50.7 watts with 13.9 volts and if my memory serves me right, about 8 something watts of power being drawn, with my MXT500 radio.

If people would stop buying CCR crap equipment and buy decent radio equipment such as Motorola and/or Kenwood for use on GMRS freqs and use the appropriate manufactures' proprietary software you won't have near the problems that people have stated in the various postings in this forum. Everything is a lot more clear and straight forward with the programming procedures.

Yes, it was the Laird 3 dB Phantom antenna I used on the rollbar. As for the performance, it is very difficult to evaluate because in the Phoenix Area, we are very fortunate to have great repeater coverage from various high elevated repeaters. The simplex communications was not a problem but the simplex was within a close group of approx. 17 Jeeps on a trail run. I used the the Phantom antenna last year on my Porsche during a National Porsche Club event in Palm Springs. I came across a severe head-on collision up in the mountains overlooking Palm Springs and I was using a Kenwood TK880 24-watt radio to call in the accident because of no cell service and a repeater station was about 20 or so miles away and I had no problem with going through the repeater. However, I have not done a comprehensive test comparison with the Phantom. Also, I have been using the non-groundplane version on a couple of my roadrace racecars over the years with composite body panels with no problem. Also, I have a couple of the Midland Phantom antennae. I really can't tell the difference between the two antennae and again, we have excellent repeater coverage throughout most of the Valley area except for south of Phoenix until you get closer to Tucson.

If you buy cheap, you get cheap junk and cheap is usually not cheap in the long run and a complete waste of time and energy. More than likely you won't be impressing the good looking chick's with a cheap piece-of-junk hanging on your belt, unless they are extremely calorie enhanced and living in the community below where Randy lives.

On Randy's postings, I've noticed the A.I. statement and never give it much thought about it in the past until today after reading his post above. A.I. is taking jobs away from a lot of people. Today, this fact is very important to me because tomorrow I am having surgery performed on my Right Shoulder and my bones are going to be reversed and this operation is going to be done by an A.I. Robot. I guess the only thing the doctor will be doing is turning the robot on and off. I guess I am fortunate that I no longer have to worry about job security and I am enjoying being jobless for the rest of my life.

It's channels 8-14 that are only a half-watt on transmit power. Channel 7 is allowed 2-watts on a FRS radio and 5 watts on a GMRS radio.

Sometimes, split tones will help minimize your own intermod.

I've used them before. I used them on two different C4 Corvettes. The ones I used before where the Antenna Specialist/Antenex Cellular Look-a-Likes. They were also great antennae and had the trimming adjustment Pot. I never had any difficulty in communicating with them at least I couldn't tell and was never disappointed in their performance.

Thus is my Larsen Glass'Mount antenna. The antenna performs better than I thought it would.

You mean mount them like this? This was a temp. install that I used on my 23 Wrangler 2Dr "IZARUBICON" while I was waiting for my Larsen Glas-Mount to be delivered.

Not all 675 repeaters uses the National Travel Tone. Some use other tones i.e. the Atlantic City 675 repeater uses 146.2 Hz in/out.

This Motorola mic is a little over 30 years old and still in new like condition and I can still use it on my HT1000, MT2000/MTS2000, and my XTS series radios. It has had a lot of use over the years.
