I never mentioned Amazon in any of my postings.

Larsen or T E Connectivity (Laird) and buy them from a reputable professional radio electronics retailer like Talley Communications, Pasternack, Arcadian Antenna, Tessco, or Antenna Farm, and not from a cheap discount big warehouse operation that only specializes in shipping cheap junk sold by resellers that knows nothing about radio electronics.

I just learned that my Dummy Load took a dump and I am wondering if they are repairable and worth repairing? The casing/housing appears to be assembled with two halves and the N Female fitting has 4 screws attaching the fitting to the housing. I didn't realize that the Dummy Load failed on me. At first, I thought that the three radios I was measuring the RF output with the Dummy Load was in a dire need of an alignment and tune since I was measuring only 7 watts of output power. I measured the three radios with three different in-line Watt meters and one of the meters and slugs were calibrated last year by Bird. So, I packed up the three radios and headed to a Motorola Service Shop in Tucson. As I was about to leave, the technician came out to my Jeep and told me the first radio is putting out 50 watts and is on freq. I said no way. He quickly checked the second radio with the same results, and the third radio was transmitting 40 Watt, but was a tad off freq and needed an alignment. I said do it. The first radio was Jeep radio so I put the radio back in my Jeep and remeasured the RF and it was at 48 watts. After the Tech tuned the third radio, I headed home and when I got home, my first task was to recheck the radios again. I checked two of three radios on the bench since they were loose, and they again only put out 7 watts. So, I started replacing cables, cords, adapter connectors, ensured the power supply was putting out 14 volts. I bypassed my Anderson Distribution Block and directly connected the radio and controlhead to the power supply, only 2 watts were drawn from the power supply. So, I tried another power supply and still only two watts being pulled from the second power supply. The only thing that I haven't changed was the Dummy load. My second Dummy load was only an UHF Dummy load and these three radios were VHF mobiles so I couldn't use the UHF Dummy load. However, I have NMO magmounts and a couple VHF mobile antennae so I hooked up the antenna to the radio in place of the dummy load. When I keyed the radio, 48 watts, hot damn. I reconnected the Dummy load, 7 watts, hooked the antenna back up, 48 watts. I decided to get out my ohm meter and check the Dummy load resistance and it measured "OL". Although, I wasted a whole day going to Tucson with two perfectly good working radios, I did get one radio aligned and I did discover that the Dummy load failed and my meters and radios were nof the cause of measuring 7 watts.

In my Motorola XTL5000 UHF mobiles, I have 35 Zones with a combined total of 860 channels programmed with GMRS for coverage in six states, and several business radio service channels. In my Motorola XTL2500 VHF mobiles, I have several business radio service channels in about ten zones in various channel configurations. In my XTS5000 UHF portables, I have 43 Zones with about the same number of channels, not to exceed 16 channels per zone. In my Motorola XTS5000 VHF portables they are essentially programmed the same as my VHF mobiles. Oh, by the way, it appears that these series radios will not allow you to program more than 50 zones. I think it is stupid that radio manufacturers design a 1,000 channel radio without any zone banks. Can you imagine trying to zip through a gazillion channels in one zone. Typical $20 POS CCR, and without PL Defeat/Monitor, Home Channel, Display with more than 6 characters, and Talkaround features.

I was comparing Trail Apples because most of the Jeepers use the little Itty bitty FRS radios and the test was also to prove a point.

I did some comparison testing measuring distances between FRS being operated inside of a vehicle and the CB Radio in both the AM and FM modes. The test was conducted on relatively flat desert terrain essentially nothing but giggley weeds and pucker bushes between the two test points at various distances. The FRS radio was operated on a two-watt channel and the maximum distance was just shy of a half-mile. The CB Radios were using 5-foot Tuneable Firestiks and the maximum distance was 2 1/4 miles in the AM mode and 3 1/2 miles in the FM mode. At the 3 1/2 mile test point and just for giggles, a 60-watt CB amplifier was turned on which barely put out 45 watts, and there was very little difference in the signal and audio qualities in the AM mode. The FM mode was not tested with the amplifier since it was not FM capable. Personally, I think the FM CB Radio could have potential use for Trail Comm.

This chart is inaccurate and is mostly confusing and contrary to the rules in Parts 95.567 and 95.1767 in respect to RF output power levels for both the FRS and GMRS radio services. The rules state that Channels 1-7 are regulated to 2 watts ERP for non-licensed FRS service and 5 watts ERP for licensed GMRS service. The left chart indicates channels 1-7 for both FRS & GMRS are regulated to a .5 watt and that is incorrect. The right chart indicates that Channels 8-14 are regulated to .5 watt ERP for FRS and that is correct, and 5 watts for GMRS and that is incorrect, all transmitter transmitting on these channels are regulated to a .5 watt ERP, regardless of the two radio services. The left chart indicates that channels 15-22 are regulated to 2 watts ERP and that is correct. Both charts indicates that the 462 (462.550, 462.575, 462.600, 462.625, 462.650, 462.675, 462.700, and 462.725) and 467 (467.550, 467.575, 467.600, 467.625, 467.650, 467.675, 467.700, and 467.725) Main Channels are regulated to 50 watts and that is correct, except for the 467 main channels, they are regulated to 15 watts for fixed class station operations. The 50-watt output is not limited to the measurement of antenna ERP for the 462 & 467 main channels. The 50-watt output limit is the measurement of power out of the transmitter before the antenna and there is no limit of the ERP of the antenna.

I believe it was 128 channels on the firmware upgrade date fof the MXT500.

If I recall, last year, I looked this up and the current treaties and agreements no longer list UHF freqs as affected freqs that have Lines A and C restriction between thd two countries. What I don't recall if that affected the T-Band freqs because since that didn't affect me, and we can't use them, I didn't care if it did of not. However, the FCC still put the Lines A and C restrictions on the Part 90 and 95 licenses.

Check the ground. Check the line voltage, and the power draw in amps, when you key the radio. Your radio will probably draw somewhere near 6-8 amps keyed and a little over an amp receiving and about a half of an amp on standby. If the voltage and power level doesn't change when keyed, the radio is not transmitting. If the voltage drops below 12 volts, the cause maybe the power source or connection. The power should never drop below 12 volts at a minimum and is looking for 13.6 volts. Also, check the codeplug and make sure there is something entered in the transmit section and correctly. Do you have in-line RF watt meter connected to verify that the radio is keying or not if the voltage/amp level does not drop. After you check the above mentioned test check points, let us know what you find out.

I meant to say "the only Midland GMRS radio" that can be programmed by both programming methods. Now, that no longer blows that theory to heck and actually it never did.

The cable and driver is only $16. The software is a free download. You should be able to sneak $16 from somewhere or cash in some recyclables, or bum the money from a friend and tell him you'll pay him back in small installment payments. You can make it happen. Maybe a Go Fund Me thing can be setup or mow some yards for the money. There are always ways to make this happen without being dishonest with your wife.

The Midland MXT500 can be PC programmed with software and is the only GMRS radio that can be programmed by either the Radio Menu or PC Software. The programming for the MXT105, MXT115, MXT275, and MXT575 are radio menu driven.

Are you programming this radio through the radio menu or the Wouxun KG1000G Plus programming software? If you are trying to do this with the programming software, how about sending me the .kg codeplug file and I'll take a peek at it and see what is going on with your radio.

Can you get into the radio codeplug at all? Have you tried to clone to see if you can overwrite the codeplug with another codeplug file? What is the operating band range of your radios?

My .dat file was read from the radio with the Radioddity CPS. I will need your email address so I can send it to you.

I have a .dat file for the DB25. Do you still need one?

Has AI ever helped in these situations?

Assuming that you are not a Government Entity or a person and/or an entity involved in basic or advance life support services, you will need to meet the eligibility requirements of Part 90.35 of the FCC Rules and Regulations. The FCC filing fees for a Radio Station Authorization (License) is $205 and that application/filing must be filed on-line. Prior to filing, you will need to file a request to register for a FCC Registration Number (FRN), if you do not already have one. I assume that you already have a FRN because in order to be on this forum you need a GMRS license and that number will be on your license. If you are filing for a mobile itinerant frequency(ies) or an approved low-power allocated frequency you will not need to have your application/filing coordinated/approved by an appropriate authorized Frequency Coordinator. If you are filing for non-itinerant mobile and/or Base or Repeater Class Station Radio Station Authorization, you will need to have your filing/application coordinated by the appropriate Frequency Coordinator and approved. The Frequency Coordinator fees are separate and inaddition to any FCC filing fees. Some coordinators have posted their fees on their websites In most cases, if you are applying for a specific frequency or a pair of frequencies, you will need to submit a radio communication propagation study/coverage plot map with the required contour plot study. You will need to provide the technical data regarding your transmitter site location, tower height, antenna placement height at the tip, output power, antenna height above the average terrain, and maybe a radiation exposure study. Also, you may be requested to provided a frequency interference study depending on the requirements of transmitter site. It my be best to let the Frequency Coordinator select an usable Frequency for your requested coverage area. It is my understanding that the FCC will not longer approve any filings/applications for Statewide coverage. They (FCC) expects filers/applicants to apply for and use itinerant frequencies for statewide coverage. Filings/applications for a specific geographical area will only be granted with a specific radius from a center point and that point must be exactly identified. Don't forget to specify all the emissions types you intend to transmit with in your filing/application. You will be regulated to the listed allocated narrowband frequencies with their respective restrictions/conditions in the Part 90.35 radio service pool. Get your Visa/Mastercard ready.

Part 90.20 is the Public Safety Radio Pool and Part 90.35 is the Industrial/Business Radio Pool.

And they were purchased from a huge warehouse operation that doesn't specialize in the sales of quality two-way radio products.

Midland MXT mobiles have 5, 15, and 50 watt mobiles.

This is my GMRS repeater antenna mount. The antenna is a Laird FG4605 5 dB Omni antenna with no guy-wires.

My TK880s will also support MDC and I have been using the MDC PT-T ID feature for accessing a repeater. Just recently, the repeater owner posted information on a recent discussion in this forum and he said that he just turned off the requirement of using the feature since his problem child apparently has stop jamming his repeater. I need to deactivate the feature since it is no longer required for his repeater access. I'll take care of that in my next quarterly programming updates for my Motorola and Kenwoods.

My guess the coverage should be at least Fresno to Bakersfield and then some and I wouldn't be surprised if it covered Madera to the foot of the Tehachapies and the Ridge Route. Mt Lemmon 725 overlooking Tucson is about the same elevation as Park Ridge 7500+ and will communicate up to South Phoenix which is over 100 miles. The Towers 575 in Crown King is also the same elevation of Park Ridge and Mt Lemmon which is over looking Prescott will look towards the south I believe to Casa Grande and maybe a little beyond which should be about 125 miles.
