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.

What channel and tone are you transmitting on with your Midland?

I was around back in the days when 462.675 was designated for emergency use only and for point-to-point communications for REACTS. My GMRS license back in that day stated that 462.675 MHz was for emergency use only. Orange County REACT was one of the licensees that had authorization to use a repeater on 462.675 MHz in the 70s and they had a repeater on Santiago Peak for all the REACT monitors to relay information. This repeater is still in existence today and still owned by Crest Communications and used by their Club members. In later years, the FCC deregulated the use of 462.675 MHz as an emergency only and the North Shore Emergency Association was instrumental in getting the acceptance of the 462.675 MHz GMRS as a highway calling channel with the 141.3 Hz as the national travel tone. Here is some info from the North Shore Emergency Association on the history of the National Travel Channel: This briefly discusses how the "travel tone" of 141.3 Hz and the national calling/emergency frequency of 462.675 MHz came to be. NSEA was one of the very first adopters of GMRS in the early 1970s, then the Class "A" Citizens Band. Here's a quick snippet from the link: NSEA members were instrumental in bringing UHF technology to other public service groups in CB, especially R.E.A.C.T. (Radio Emergency Associated Citizens Teams). Beginning in 1976 key NSEA members spent extensive time meeting with REACT teams in more than a dozen-and-a-half different states, bringing a portable repeater, together with a number of mobile and portable units for field demonstrations...As a result, over 200 personal use repeater systems (all on the same frequency [462.675 MHz]) were set up throughout the United States. In recognition of this trend of explosive growth the Federal Communications Commission formally recognized our frequency [462.675 MHz] as the national emergency and traveler's assistance channel in the Part 95A Rules and Regulations. Below is some info from Wikipedia on the National calling and highway channel; GMRS: 462.675 MHz is a UHF mobile distress and road information calling frequency allocated to the General Mobile Radio Service and used throughout Alaska and Canada for emergency communications; sometimes referred to as "Orange Dot" by some transceiver manufacturers who associated a frequency with a color-code for ease of channel coordination, until the creation of the Family Radio Service, in 1996, "GMRS 675" or Channel 6/20 on mobile radios today. It can have a repeater input frequency of 467.675 MHz, and a tone squelch of 141.3 Hz. The national calling channel is still recognized by some GMRS users and Clubs that are still alive and well but the channel may not be widely recognized by the newer GMRS users today.

Channel 20, 462.675 MHz, has been designated as a Travel Channel with 141.3 Hz encoding only, as the Travel Tone, with CSQ on receive, for the last couple of decades.
