A couple of years ago there was a Doctors office near me that was using GMRS. I set my simplex repeater on that frequency and PL for a few days...after that, never heard them again. I guess having to hear themselves repeated back all day was annoying! Imagine that. 

I don't see much of an issue with any of it. Might simplify things a little, doesn't affect me at all from what I can tell.

I ditto on turning the power down. 20/25 will do as well as 40 in most cases, as the higher the tx power the more chance of drowning your input, even with dupexor (unless you are spending $3,000 on it, and even then I have turned them down to necessary power only. 
 
When I worked for M we had a customer that used a 25 watt mobile for 2 way and phone interconnect, and 2 HT600 portables, but her repeater antenna was on a 500 foot tower she owned. We had the repeater all rigged up blowing A/C directly into it, as she liked to use that phone for 20-30 minutes at a time, and it was an R100 repeater! We had it set down to get about 2 watts out the antenna, and it had great coverage, more than she needed.
 
Input path to the repeater will determine the usability in most cases not power out. Too many guys have CB mentality, not what you need.

No, I'm afraid it's not "all fine". Follow the rules. I have read a couple of your posts, are you here to participate or instigate? Sounds very negative to me. I think I can speak for all members in saying we welcome participants....not problems. Let's don't be antagonistic...or maybe this isn't the site for you.
 
And furthermore...a 300 watt repeater has no better usable range than a 50 watt repeater if the receive isn't enhanced. 4 watts from a portable still only goes so far to reach a repeater....300 watts is just "broadcasting" and is likely hurting the receive side more unless using high dollar cans, pre filters/selectors, etc.
 
Moderator - if I am being too forward with our new member here, please delete. Just calling it as I see it, and don't want something getting out of hand.  

I must have misread your original post. One of the problems with skipping the type acceptance and having the FRS -only channels programmed is that those frequencies are the interstitials on the 467 side of things- so, adjacent to repeater input frequencies. I would be less than pleased if you were operating a radio like that and unintentionally jacking with my repeater because you were running 10 times the power allowed on a very narrow adjacent frequency. Food for thought.

I guess to each his own, as long as one is responsible and knows they cannot transmit without a license (unless it is a dire emergency where life is in danger) I'd say it's not a big deal. I have had HAM in my radio in the past, but I always had them set for RX only.
 
Now on the other hand....shame shame shame on the (presumed) Hams around Cinncinati Ohio last weekend that were on a repeater using 4 letter call signs (WQWY, W5JZ) and Ham lingo. If they have a GMRS license, that's fine, but they should NOT be using their HAM calls on a GMRS freq....regardless. If I went on their HAM repeater and used my GMRS Call sign...they would send out a lynch mob and call their senator crying about their rights!  

Probably has it hooked to Skype or one of the PTT apps...to make his "nationwide network". 
 
Sounds like a mess to me.

It's intermod. 

They use a somewhat legitimate concern to hide the fact they just want to "hide" all traffic. Most sensible agencies use a secondary talkgroup, which can be encrypted when needed. 
 
Where I am, there is a large P25 Digital system, works great, and not that much is encrypted...and if they need to sometimes, that's fine. However, what cracks me up is that the State Police, Local agencies that are on it, and other much more secure-oriented agencies don't use encryption much at all....but the State Forestry Division does - full time! That is stupid...are they trying to protect the identities of innocent trees and animals? Give me a break. 

Yes, use TSQL for TX and RX tone. 
 
I agree, use another channel, if one is available with no current use. I used to setup a receiver and a tape recorded for a week at time years ago to find conditions on certain channels that coordinators would send back as possible good ones for public safety and business. Not that any of them should have been used and undocumented, but just to check for skip, etc.
 
I have done same on GMRS with a program called ScanRec for windows...which is essentially a Vox audio recorder. 
 
Find the cleanest one you can, and even if you don't use your repeater much, at least get on and do a radio test and ID a couple times a week, so if anyone else is doing what you are, they at least have a shot a knowing you exist. About all you can do with a self coordinated service. 

Yes, simple and effective. I used it with a cable from my receiver to the audio in on the PC. Great recording.

This is from a legal newsletter:
 
Enforcement Bureau’s WirelessTop-10 Violations ListAt this month’s Land Mobile Communications Committee(LMCC) annual meeting, the deputy chief of the FCCEnforcment Bureau presented his “Top-10 List” for wirelessviolations. Interestingly enough, there was a commontheme with most of the violation types that the EnforcementBureau discussed – namely, interference.Absent from the list however were antenna tower violationswhich we know remain an important compliance forthe FCC nonetheless. 10. Non-compliance with the narrowbandingmandate. Enforcement stated that this is moreprevalent with older systems that have not beenreplaced or upgraded.9. Poor Engineering. Engineering which causesinterference to co-channel stations, or interferenceresulting from spurious emissions and harmonics.8. Licenses held by corporations that have beensold, suspended or are otherwise out of business.This makes it difficult for the FCC to resolve interferenceissues that could normally be handled bya simple phone call.7. Unlicensed operation. This problem is on therise due to the purchase of radio equipment fromretail outlets, without attention to the need forFCC licensing. Offending users are most prevalentin the retail, hospitality and auto industries.6. Itinerant or special event interference. Interferencebetween special event radio operations underspecial temporary authority (STA) (e.g., carraces, rock concerts, etc.) and incumbent licensedoperations. Caused by frequency congestionwhich makes interference free operation underSTA more difficult. Special event operations mustbe careful to coordinate with incumbents to avoidinterference.5. Failure to properly monitor shared channels beforetransmitting (for Part 90 and other sharedspectrum operations)4. Failure to properly identify your station call sign:Enforcement is going to crack down on this becauseit frustrates efforts to identify the source ofinterfering signals.3. Frequency Warehousing. Created by a failureto construct or by permanent discontinuance ofoperation without returning spectrum to FCC.2. Control Channel Trunking on Conventional UseChannelsAnd the number one wireless enforcement issue . . . .1. Monopolizing shared channels. Shared channelsmust be shared, and licensees that broadcastsignal continuously or fail to monitor beforesending signals can be fined. 

If the repeater is wide band, you will want to work it with wideband, likewise you will get the best performance from your radios in wideband. GMRS is not required to use narrow, and range is diminished with it as well.

Can't beat that MTR for solid performance, I run one with a Zetron and a ASP fiberglass antenna (800 model I think) 22 feet long on my 50 foot tower, which is on a hill 150 feet above average terrain. It has always provided good range. Before the MTR, I had 2 mobiles running, it was good, the MTR is the real deal though. For duplexing I run 2 receive cans, and one transmit can, stuff salvaged out of an old Motorola community repeater. Works great.
