Recently, a local Phoenix family drove up to the mountains northeast of Phoenix several days ago and got caught in a snow storm and they were stranded for several days. The family did survive and made it out unharm. They were lucky to be found by local Payson Area residents during the snow storm. While they were stranded, they attempted to call for help using their cell phone but unfortunately, they were in an area of no cell service, which is not unusual in the remote mountain areas of Arizona. However, the area they were in was well covered by the Diamond Point GMRS Repeater which is linked to other repeaters of the Southwest Community Radio System (SWCRS) that serve the Flagstaff, Phoenix, Tucson, and the eastern mountain communities in Arizona; and throughout the state of New Mexico. If they had a GMRS radio and if they were licensed and knowledgeable about the GMRS repeater system they could have use their GMRS radio to summon for help. The point is, you can’t always rely on a Cellular Telephone for help, especially in remote areas. So, don’t leave home without your GMRS radio even in the metro areas. You can never plan when a GMRS radio will be the most valuable tool in the time of need.

And it won't, as long it is completely compliant with Part 95, subparts A and E.

A 3 X 5 is an Index Card. https://www.grainger.com/product/10R346?gucid=N:N:PS:Paid:GGL:CSM-2293:99F1R6:20501231&gad_source=1&gclid=CjwKCAjwnv-vBhBdEiwABCYQA-Oks7zKch__SP6G2r5GATaxNpbBAGXCBQV2UWKx6ruIopnXgsID-xoCkmEQAvD_BwE&gclsrc=aw.ds

That is actually true. I will only buy Motorola and I am pretty much set for some time now. I have numerous mobiles and portables of various models all UHF except one VHF XTS1500.

When I identified the desense problem with the two KG1000 Plus radios I called Buy Twoway Radios regarding this issue. I explained the extensive trouble shooting procedure I used and what were the results and they essentially in a matter of words said my test procedure was flawed and that no one else was having this problem. They did say send back the radios so they can performed their own test and if the radios performed as designed they were not going to refund my purchase. I sold the two radios as single units. I will never do business again with that dealer or buy any CCR in my lifetime. I learned my lesson.

Vertex Standard EVX-R70-G7-40 Repeater using an EMR Corp Duplexer connected to a Laird FG4605 5 dB Omni Base Station Antenna with Times Microwave LMR400 Cable with a Polyphaser and the antenna tip is at 30' AGL

Just for giggles, I decided to test my Midland MXT500 that has the latest Firmware update with 128 channels to see how much power I am putting out. I normally let my friends use the radio as a loaner when they are radio-less when I am on a Driving Tour with one of my car clubs or one of my Jeep Clubs on a Trail Run. This is a great radio for that purpose. I ran my tests with my recent recertified Bird 43 Watt Meter and a recertified 100 Watt 200-500 MHz slug and a brand spanking new 10 Watt 400-800 MHz slug to check the reflection. I also used two 12" test leads with N Connectors to connect the radio and an EMR Corp. 0-1 GHz 125 Watt Dummy Load. The first phase of my test was transmitting into the dummy load and the results were, on 462.550 MHz was 52 watts and transmitting on 467.725 MHz with a result of 51 watts. The second phase of my test, I connected the radio to a Midland MXTA25 3 dB Phantom Antenna with a Midland Mag-Mount and cable sitting on a cookie sheet and I measured the VSWR at 1.4:1 at 465.000 MHz with a RigExpert Antenna Analyzer. On 462.550 MHz I measured 52 watts with .6 watt reflected and on 467.725 MHz I measured 51 watts with .7 watts reflected. I had my Midland MXT500 radio powered by a Powerwerx SPS30DM Power Supply set at 14.3 DC Volts and the power draw results for both frequencies on transmitter keyed are as follows: 462.550 MHz 8.61 AMPS at 13.59 Volts; and 467.725 9.71 AMPS at 13.51 volts. I guess I can't complain about the RF Output Power with this radio. However, I do have some minor complaints with this radio such as, no Talk Around, Monitor (PL Defeat), Zone/Bank of Channels features, and the absence of some CTCSS tone freqs. Other than that its not a bad GMRS radio.

The desense problem is not an antenna issue. The desense issue is with the two radios that don't have any shielding and the transmitting radio emits EMI directly into the receiver of the receiving radio. Also, if you are using a Cheap Chinese Duplexer that cost around $150 you're just compounding the desense issue with a crappy duplexer. You need to spend close to $400-500 for a decent duplexer if you setting this up at your residence and not at a radio remote site

Those were not only constructive comments, they are facts. Using two Wouxun KG1000 Plus radios side-by-side configured as a repeater, you will experience a horrendous desense problem whereas you'll be lucky that receive radio won't receive even a 50 watt mobile more than a mile away.

All frequency pairs between 450 to 470 MHz are +5 MHz for mobile transmit to the repeater. All freq pairs above 470 MHz to 512 MHz are +3 MHz for mobile transmit to the repeater.

462.5325 MHz is not an allocated Part 95, Subpart E frequency.

I got about a mile and a half with my DTR700 in a holster on my belt sitting in a car and was able to monitor other DLR1060s that were out in the open.

Yes, Business Radio Service freqs.

Some of the radio features to consider are: 1. Talk Around/Direct/Simplex Operation 2. True Monitor (PL Defeat on Receive) 3. Multiple Radio Zones (the ability to have various number of channels in a Zone/Bank) 4. MDC1200/PT-T ID (some repeater owners are starting to implement this feature to validate access for authorized users.) 5. Split tone operation and ability to encode only with CSQ operation on Receive. 6. Narrowband and Wideband Channel Operations 7. Radio Model with After-Market Support for batteries, accessories, and programming software. 8. Frequency Agile for full bandwidth of the Radio Operating Band Range (i.e. 450-470MHz) 9. Ability to have 250 or more channels. 10. Radio model with large capacity (4000 Mah or more) batteries.

ok, that might work better

Your number comes back restricted.

I am home now. Do you have Diamond Pt. link channel with the Midland Privacy Code DCS 10 programmed on your RP 16 channel yet?

This radio service does not have frequency coordinators like the various services do in the Part 90 world. It's still the Wild Wild West and if you're in the eastern portion of the country It's still the Wild Wild West. You are free to do whatever you want as long you are compliant with the applicable Part 95, Subparts A and E.

Well, if you are hearing the Station ID'r then you should be hearing the repeater with no problem. Just make sure that you have your radio set for Repeater Channel 16 with the 82.5 Hz tone set only on the transmit side and when you key it you should hear the repeater squelch tail when you unkey. When I get home, I can walk you through setting up the link on Diamond Pt. so I can talk to you from Sun City West through the Shaw Butte repeater link. You will need to set up another channel and transmit 467.575 with the DPL D065N code and receive 462.575 with no tone/code on receive. The Midland code for DPL D065N is DCS "10". What is your Callsign?

I'll be back home in a couple hours. When I get back I'll check and see if the repeater is up running. The repeater owner has been doing some upgrading on his repeaters lately.

You are practically under the repeater so the power loss you are experiencing shouldn't prevent you from hitting the repeater, you'll probably just not hearing it if you have a tone set on the receive channel.

That'll help temporarily. You just can't have any tone set on the receive side

No tone or code protection on the receive channel. Diamond Pt. does not transmit any tone out nor does any of the 575 transmitters up in that area. CSQ means Carrier Squelch.

Make sure that you are CSQ on the receive frequency and that you're on RP16 to transmit on 467.575 for Diamond Point.
