I wonder what would happen if I use some TV 300 ohm flatwire on a CCR. I'm sure the VSWRs would be a tad off. Does that TV lead-in wire even exist these days?

Does anyone have any experience with the subject radio. I just acquired my first FPP XTS5000 radio just to see if I would like it or not and try to master the programming of this radio. It is definitely a different animal. Is it normal for the first seventeen Conventional Personalities be hard program whereas you can only change a couple of the settings like power setting Analog or Astro Digital, Scan List, etc.? Also, you can not change the change the conventional personalities in Zone 1 and they are hard programmed personalities 1 through 16 for each of the 16 channels. In addition, you can not insert channels or zones except for at the end nor can you move any channel or zone around. I haven't learned how to do the FPP yet and I'm not sure that it is a big deal for me to FPP. I have well over 500 channels programmed in 35 zones that very well meets my needs for not only GMRS but also my Part 90 freqs as well. I think the FPP feature on this radio not only limits my ability to amend the data my moving things around and insert as I please but I think the FPP feature is over rated. I prefer that I have the ability to amend (insert and/or move) the data in the Zone Assignments more than having the ability to FPP the radio. Is it normal for the 16 fixed personalities be like that in the first Zone?

I think it may have been one of those Ham guys saying something to that affect. I do remember the Jeep guy that drives a Nissan had a video to the contrary on that subject. No antenna definitely affects your farz. Its best to use the right antenna.

It could have a relay that senses the transmitter keyed up and shut down the receiver during that period of time like a semi-duplex configured station.

All the above.

You're absolutely correct and that is why I am a lowly GMRS and Part 90 Business Radio Service user. However, that was kinda rude.

No experience with that Brand. I kinda stick with name Brand that are used in the Part 90 world on Public Safety systems. Ok, sorry, my mistake for thinking you're a HAM. Relative flat area along the coast you must be in Southern California from Santa Barbara to San Diego or its on the East Coast. There is no relative flat area along the west coast from Santa Barbara to Canada.

Yes, CCR ones in a Suitcase type box.

I thought I read somewhere that you said you're a HAM? If you're a HAM with one of the three HAM licenses in the Amateur Radio Service, shouldn't you know that my mud is not that muddy and you should be able to see clear through the murk? I thought that murk stuff was on the HAM test? I'm not a HAM, so I can't talk HAM talk.

My repeater and antenna is permanent and legally you won't find too many repeaters that you can use in the Part 95 world. You can't exceed the maximum power input of 50 watts. Most UHF repeaters are usually at 40 watts of RF Output power. However, there are Quantar repeaters that have up to 100 watts of RF Output power whereas you can set the RF power level to 50 watts to be legal but you're not going to gain that much more distance with the extra few watts. A high gain antenna ill definitely help and there is no restriction on the ERP for the main 462/467 MHz channels. Before you buy a high gain antenna, checkout the technical spec sheet and see if the radiation pattern is what you're looking for.

The Bird shows 2 tenths of a watt being reflected back into the radio because the antenna and transmission line is almost gnats-ass bitchin.

My repeater puts 37 watts into a dummy thus would be the same into the duplexer

My reflected power with a 10 Watt slug

And those many factors will affect all radios operating within the same parameters. That means if the CCRs are transmitting at the same power level as a real radio, will have just about the same amount of farz. I believe one of the video stars proved that in one of his videos.

I have a Repeater and my Repeater setup is as follows: Repeater - Vertex Standard EVX - R70-G7 403-470 MHz 40-Watt Analog/Digital - Tx - 462.625 MHz/Rx - 467.625 MHz Receiver Port Connector - Female BNC Transmitter Port Connector - Female "N" Connector Antenna - Laird FG4605 5 dB Omni-Directional tip at 30 Feet AGL Transmission Line - Times Microwave LMR400 27 Feet Total Run from the Polyphaser to a Termination Point at the Duplexer. From the Polyphaser to the Female "N" Connector at the base of the Antenna approx. 20 Feet, including a drip loop, not to exceed total length of 25 Feet. Polyphaser Lightning Arrestor with Gound to Existing Earth Grounding Point with 8 Gauge Wire. Duplexer - EMR Corp #65316-0/MC(5G) - six cavity duplexer with female "N" Connector ports. Duplexer Jumper Cables - Times Microwave Low Loss RG-8X Coaxial Bulk Cable 100 Feet in length ordered. Receive High Port - 14 Inch Cable Length with Amphenol #112533 BNC Male Solderless Connector (Repeater) and Amphenol # 172135 "N" Male Solderless Connector (Duplexer Connector) Transmit Low Port - 12 Inch Cable Length with Amphenol #172135 "N" Male Solderless Connectors on both ends. Antenna Port - 12 Inch cable length with Amphenol #172135 "N" Male Solderless Connector (Duplexer) and Amphenol #18211510 PL259 UHF Male Solderless Connector to Mate with Antenna Transmission Feedline with an Amphenol #AML-83-1J Double UHF Barrel Connector. (The Antenna Installer did not have a Female "N" Connector for a LMR400 Cable at the time of install so I was stuck with the PL259 UHF Male Connector) NOTE: ALL JUMPER CABLES WERE FABRICATED/ASSEMBLED BY A LOWLY LICENSED GMRS USER (ME) IN THE OLD PEOPLE COMMUNITY OF SUN CITY WEST ARIZONA

FYI - I found horrendous amount of desense between two KG1000G Plus radios that were side-by-side. With a Motorola XTS5000 portable radio transmitting 3.7 watts, I only got .7 mile from the repeater on flat terrain, in otherwords just straight down the street before any turns until the mobile could no longer be received by the receiving radio when the transmitting radio was keyed. The TX out was no problem in being received by the mobile or portable radios. With a 50 watt mobile measured with 44 watt of RF output with a 2.4 dB omni mobile antenna with a VSWR of 1.2:1, I got about 1.8 miles. At first, I thought my problem may have been the duplexer or a cable or two but everything swept out good. I stopped the duplex function and I ran a test transmitting through the duplexer and the same antenna with one of radios in the simplex mode, and received on the other radio with a separate antenna and drove around using a portable and had great results and farz throughout the area of at least 5 miles away. I reversed the testing procedure of receiving through the duplexer and using the same antenna connected to the duplexer and still had great results as before. That procedure essentially eliminated the duplexer and cables as being the problem. However, I took the duplexer back to EMR Corp to have them recheck it and it was performing as designed and tuned. I reconnected the duplexer and ran my test again and still no farz with the two radios acting as a repeater. I called a friend and asked him to bring over his two Maxon radios configured as a repeater and ran my same test and used the same TX points and we got many farz. This test results proved there must be a desense problem probably due to poor shielding between the two radios. The function of the two radios were also reversed and that did not change the results. So, I learned my lesson in trying to go cheap. I decided to buy a real repeater station and installed it. On flat terrain, I got about 10-12 Miles with a portable and about 22-25 miles with a mobile radio. And my duplexer is still working great and has not burned out the plastic inserts like the cheap duplexers are doing. I called the selling Dealer, because the two radios were still under warranty, explaining the problem that I was experiencing and my testing procedure. The Dealer's Tech Support person essentially questioned my testing procedure stated that my testing procedure was not technical and scientific enough for me to arrive at my conclusion. I told him that I am not an engineer but it still was a real world in the environment testing with poor results from the two radios acting in tandem as a repeater unit and fine as separate simplex stations. Well his candor really gave me a warm and fuzzy feeling that I was in a favorable position so I just requested a refund. He stated that I need to ship everything back so they can conduct their own test in order to get a refund. Fortunately, I was able to sell one of the radios and for some stupid reason thought it would be a good idea to keep one of them for another base station. That was kinda of a mistake, oh well. Never again. I sold one of the radios to a Club member and kept one as a second Base radio mostly for monitoring two other nearby repeaters.

I have seen up to 9 watts of reflected power loss from a cheap non-nickel plated 90 degree elbow fitting with a 50 watt rated radio and an antenna that was metered with a VSWR of 1.15:1 on a 462 MHz GMRS freq. (No, the antenna did not perform at VSWR of 1.15:1 with that elbow. The antenna was swept without the cheap elbow.) If you go cheap your radio will perform as for what you paid for, "NOTHING".

The reason why I'm using the aforementioned two antennae is because I wanted vertical separation not only for between those two antennae but also from this antenna for my Repeater Station.

I'm also using the same antenna mounted in a garage window with a short 16' run of RG-8X for another Base Radio. Unfortunately, this radio is not a Motorola radio. It's mostly used for monitoring and if necessary for accessing nearby repeaters.

For one of my Base Radios, I'm using a Motorola XTL5000 Dash Mount Radio with a Desk Microphone. I'm also using a Motorola XTL5000 Remote Mount in my Truck. The Kenwood TK880 is a great radio but I'm very partial to the professional/public safety version Motorola mobile and portable radios. I won the Kenwood in a raffle and it has been refurbished and came with a DTMF microphone. As being a long time Motorola user, I originally thought that I would just give the radio away to a new Club member. After playing around with it for awhile, I kinda like the radio and I ended up keeping it and using it in one of my cars that can't accommodate a two-way radio installation. It does work great in that car because of its small physical size, low powered (25 watts), and with a low power draw on the electrical system (about 6.5 amps).

I'm using a Laird B4502N Non-Ground Plane mobile antenna in the attic with a 35' run of LMR400 coax for one of my Base Radios. Just make sure that the antenna is tuned for the location you end up using. Don't tune it in any other location.
