DH, I have to say that you alone have had more problems than all of my customers combined!!!! You burn up, break more units than anyone. You get the worst range of anyone. Yes, we all have problems from time to time. Yet you have more than all combined. Is that not strange!! Don't take this as a personal attack. Since all your posts show this to be factual information!
I really have to be sounding like a broken record on a lot of this stuff. The guys in my group have yet to burn up a unit using a high powered radio. WHY, again it is because WE DO NOT USE A TRUCK MOUNTED ANTENNA!!!! Perhaps the big letters will help this sink in. I give all my customers a warning about them. I flat tell my customers I do not like to sell them!! Strange how most will listen to this, and as a result have few problems!
Like I have said also using the MURS band is foolish!! You know that is what Garmin uses, so why use it. Have the radio programmed to another channel. Change the channel. It's not that hard. The FCC does not give licenses out to use these channels with higher power. 2 watts is the max allowed. The units are shielded to 50, and the collars are putting out 2 watts. So if using the channels legally. You should not burn on up. Even if you are using a truck mounted antenna. Since the unit is designed to receive 2 watts. So if this is burning your radio up. You are doing something wrong, and perhaps illegal.
Being that the units are shielded to 15 watts. A peanut farm using 15 watts on another channel should not harm the unit. Perhaps if you are using a truck mounted antenna, but unlikely.
EMS DOES NOT USE MURS!!! Yes, wamart does with 5 watt portable radios. Possibly could cause a problem, but doubtful as well. Still why would you need to sit in their parking lot with your tracker on?? As for the EMS. I have sat right next to them shooting the bull. Never had a problem yet. In our area they area most LEOS are using digital radios now. Which have the potential to cause more problems. Yet I have not had one. Again though, NO TRUCK MOUNTED ANTENNA!!! Fire, adn ambulance are still using analog here due to cost of switching over. No problems there either. Hwy dept. is also analog using 151 channels. Sit next to them during races. Some will stop just to listen and BS for a few minutes. Never a problem there either. Again though NO TRUCK MOUNTED ANTENNA!!
So it sounds to me like there is a very common element ringing through all that. What do I know. I'm just a dumb northwoods redneck.
Range, well that is all over the place. Depending on terrain,etc! Been over this many, many, times in great detail. Personally I get the same range with my Garmin and better than what I got using a beep beep box. My range is very comparable to what most are getting. Yet there are many that get far better than I do. I hear from a lot of folks that get as much or more than 12 miles. Mostly in the mountain ares where the line of sight is greatly increased. I always find it funny how some guys with beep beep boxes will say the are getting more range from the collars then they are the truck mounted radios. How is this even possible?? It's not under normal conditions. So the BS is quickly pointed out.
Yes, Garmin has it flaws. So does every other product, and thing out there. Nothing is perfect. At least that I am aware. Even if the Garmin was perfect. Hman nature would have someone complaining about something. To costly, to heavy, screen to big/small, and on, and on!!
The 2 bigges things right now I believed need to be changed are. The antenna connector needs to be more rugged. The second would be the allowing of more channels. The first one could be done with little cost increase to the consumer. The second however is far more difficult. It would take a huge amount of money for licensing of channels through the FCC. Which would increase the cost greatly. Even if Garmin was to place the overall licensing on the consumer there would still be costs involved. Then you would have an extra cost to get the license your self. Jut like you are supposed to with the FRS/GMRS radios. Which many own, but are not licensed. They just take the chance of getting the fine!
Lastly, earlier I made mention of the argument ANTI's made about them making hunters lazy. The pointed out how most of use have seen folks watching the screen instead of watching for the game, and listening to the dogs. Well, I seen it again this weekend. My own daughter missed a shot opportunity because she was watching the tv, and not watching for the game. Did this make it easier to harvest the critter. Nope made it easier for it to get a way. Giving me another reason to be giving a tounge lashing for not paying attention!!! Kinda shot the ANTI argument in the butt, Yet gave the womens group another argument for verbal abuse.

Only because she is 18, otherwise it would have been child abuse
When someone finds perfect products out there. Please let the rest of us know. Since I have yet to see any.
