Oops sorry, my mistake.

How to build a repeater for beginners.
nokones replied to shevo7385's question in Technical Discussion
I paid $700 for a brand new still in the box Vertex Standard EVX R70 G7 40 Watt UHF Repeater Station still in the box. This repeater is actually a Motorola XPR 8400 and this repeater performs very well with great selectivity. The station can operate either Digital or analog. The seller I bought my unit from had 2 or 3 other repeater stations for sale at the time. I am really impressed with the portable coverage from this station and the mobile coverage has been great on flat terrain. I was not happy with the two non-American mobile radio units tied together as a repeater station. I couldn't get more than a 3/4 of a mile distance from the portable and the station because of the poor shielding between the two radios and I was using a quality American made duplexer with an American made antenna system. Although, the Repeater was made in Malaysia, at least it is owned by an American company.- 24 replies

The Midland MXTA 26 Phantom Antenna is surprisingly "Not Too Shabby" in performance. Also, the Midland Mag-Mount NMO Base is not-too-shabby either except for the PL259 which is a "POS". Just replace it and it will be a great mag-mount base. Mr. Randy NotaRubicon did a You Tube review comparing the performance between the Midland MXTA 26 Phantom Antenna and another antenna which, I can't remember now, and the Phantom Antenna was equally to a Tad better in the "Farz" category. I use the Phantom Antenna while I am in the Greater Phoenix Area but, when I venture out I'll either use the Laird B4502N 2.5 dB 1/2 wave no springs antenna in the foothills and when I am in the mountains I'll throw on the B4505CN 5 dB no spring center load 1/2 wave antenna.

Wouxun KG-1000G Plus Faceplate Mounting
nokones replied to Stiemey's question in Technical Discussion
Might want to look at the Ram Mounts as an option. I'm using various lengths swivel arms on the "B" sized balls and the RAM Cans in my center console cup holders for my Radio Control Head and Rand McNally Navigation TND740 System and a suction cup on the windshield with two long swivel arms with a double ball joint for my cellphone holder. -
GMRS Required (and rentable!) at Texas Off-Road Park
nokones replied to Over2U's topic in General Discussion
Are they using simplex and what channel or are they communicating through a Repeater? If a repeater than it is GMRS and more than likely more than 2 watts, than a license is required. -
What is the longest range repeater in your area?
nokones replied to WashingtonMatt's topic in General Discussion
My Sun City West 625 Repeater has a Laird FG4695 5 dB omni antenna about 30' to the tip and I am getting about 20 miles out on flat terrain. -

I noticed there is a "Node Number" listed on some repeaters and some without a "Node Number". What is the point in having a "Node Number"? Who hands these numbers out to the various repeater owners? Just curious if that is something I should look into for my Repeater Station.

AUTOMATIC REPEATER STATION IDENTIFICATION
nokones replied to nokones's question in Technical Discussion
Thanks. I remember the manual referencing it but, I wasn't able to see it in the CPS. I didn't realized that I had to change the View from Basic to Expert. So, uploaded the codeplug and waited almost 20 minutes for the station to ID and nothing. I keyed my portable and it ID. I guest it stays quiet until there is traffic than IDs. I did set both timers for 15 minutes. Thanks again. I appreciate the help. -
Does anyone know where I can buy a complete plug and play automatic station ID unit for my Vertex Standard EVX R70 repeater? Or know anyone who would be willing to build a complete plug and play unit?

Also, back in the 90s the FCC rules prohibited Government entities to use FRS frequencies for government communications. Today, the rule is no longer in the regulations.

Brand new and need help accessing repeater

Not CTCSS. What radio are trying to program. -
Brand new and need help accessing repeater
nokones replied to WRWG621's question in Technical Discussion
Program your portable or mobile to transmit on 467.575 MHz with DPL 311 encode and receive on 462.575 MHz with DPL code 311 decode. More than likely, this repeater may be set for wideband operation. Since there is notation, you should program this frequency pair for wideband. What make model radio are you using? You might have to convert the DPL 311 to a programming code for your specific make radio. -
Select/click on the repeater icons near you and go to the details of that specific repeater station. The details usually will indicate a specific input Tone for local repeater operation only, and a different input Tone for network connected operation.

I think the Flagpole is a great structure for an antenna. The placement will be critical insofar as the length of the cable run. Unless you plan to place it next to your home and very close to your radio room, you may want to consider using foam helix for your cable run. Although, the pole will be grounded by being placed in the ground, it is my understanding you still want a grounding system tied into your earth grounding point with the house.

I'm glad that I could help.

Oops, I was assuming that everyone would have one of these for some reason. At the moment, it may be a one-time need but, in the future there is no doubt that he'll have a need for the tool. And if he goes with both DX Eng. Tool kits, it'll cost him about $19 more than the Times Mirror kit but, he'll get more cable strippers and the two cable holders. https://www.dxengineering.com/parts/dxe-ut-kit-cc1

Why wouldn't this kit do the job just as well as the Times Mirror mega dollar set? https://www.dxengineering.com/parts/dxe-ut-kit-crmp2#overview

After programming my Vertex Standard EVX R70-G7 repeater it would appear that there's not much to programming other repeaters, its not like programming a mobile or portable with tons of features. I assume most repeater have very few programming parameters such as, TX & RX freqs and tones, analog or digital emissions, power level, TOT, and hang time. Repeaters should be a piece-of-cake, insofar as programming. Just make sure that the duplexer is properly tuned and you build your cables with quality low-loss coax cable, and connectors.

If you are asking the question for the post above your last post, an EMR Corp. 6-cavity Duplexer.

SWR was about 1.3-1.4 measured with a Bird and a MFJ between the duplexer and the antenna. The reception at the portable was fine. The problem was the reception of the portable to the repeater unit and I did swap the two radio functions. I even conducted a test in the simplex mode and the coverage was far better, whereas, I had excellent communications miles between the same portable radio and the same antenna. Also, the duplexer was swept again by the manufacturer and the duplexer was tuned properly The problem with the Wouxuns had to be a desense problem between the two radios. Apparently, the shielding on those radios are non-existent. I have heard other people had to separate and shield the radios in metal boxes to get them to work in a repeater configuration. I don't know what the problem was with the Maxon radios, they were not my radios. Due to the fact that the Vertex Standard Repeater works extremely well and the the Vertex repeater is essentially a Motorola repeater, the performance proves that Vertex repeater is a better quality unit as opposed to the Wouxun and Maxon radios. The Vertex repeater is a true repeater with excellent selectivity and sensitivity, and not a two mobile radio configuration. The Vertex repeater is also a Continuous-Duty repeater whereas, mobile radios are not designed/engineered for continuous-duty.

Those reflectors are normally used for operational fixed microwave control paths.

Back in the early days of GMRS, businesses and corporations where granted GMRS licenses. Those licenses were frequency and location specific. If those licenses were originally granted before July, 1987, were eligible to be grandfathered and if they were grandfathered and renewed and valid may continue to operate per the specified restrictions and limitations of the grandfathered Radio Station Authorization (License) per Part 95.1705(g).
