DMR IDs are only sent from/to whomever you contact. Most of the CPS requires an ID but the only purpose is to identify units on the same network.

You probably should use this coax from Gigaparts: ABR400-Ultra Flex 18ft RG8 Coax Jumper w/ PL259 Ends 25400F-PL-18 $72.95

I use this antenna when out and about with my tripod. Diamond Antenna X30A Dual-Band Base/Repeater Antenna and the radials provide the ground plane. https://www.amazon.com/Diamond-X30A-Dualband-Repeater-Connector/dp/B07MHRQLPZ/ref=sr_1_5?content-id=amzn1.sym.2e97d935-d5f5-4935-88bd-cb6d2a136d95%3Aamzn1.sym.2e97d935-d5f5-4935-88bd-cb6d2a136d95&dib=eyJ2IjoiMSJ9.9gr60MfiQ3rLkc-wuJNMNsh33FjzOsgb6_kDN23UovpO84RiADkVij7Md6Fv47tNcLcJNjp-c4i5G-4uo1hEL2b-bhsv6nco4SXPn2xhepbzgHC6VBbzgKt_ZYcFjVUZjo8tG_NymETIRSjyYYSjTFj6AIRvzv8ZPAjfLkMrF9KB-xE8FVHry9zLDv2J-uj3csGAdtdO7i1kL0mnVSxNI3d31Vzoj4ArC2kUyvEK200.daQJzEPpZIEL2NL220nwEeuxkzht5SriXV6_v_o6Z_I&dib_tag=se&keywords=diamond+antenna&pd_rd_r=3a490f52-44c2-4485-b72b-f7ce79001c9f&pd_rd_w=QoDRC&pd_rd_wg=tnwf7&qid=1754868332&sr=8-5

Tie a string to the tip and hoist it into a tree. You'll be surprised. You'll need to look at the POTA website and tell people what frequency you'll be on and when so hunters can find you. {

No, Heliax isn't very flexible. It's intended for fixed antenna connections. You could do two runs, one outside. one inside./

That's correct. Trunked systems pick an unused channel for each transmission. A conversation can have multiple transmissions. l

Over use of call sign announcements on GMRS
BoxCar replied to SvenMarbles's topic in General Discussion
47 CFR 90.7 Base station. A station at a specified site authorized to communicate with mobile stations. Mobile relay station. A base station in the mobile service authorized to retransmit automatically on a mobile service frequency communications which originate on the transmitting frequency of the mobile station. Mobile repeater station. A mobile station authorized to retransmit automatically on a mobile service frequency, communications to or from hand-carried transmitters. Mobile service. A service of radiocommunication between mobile and base stations, or between mobile stations. Mobile station. A station in the mobile service intended to be used while in motion or during halts at unspecified points. This includes hand carried transmitters. And yes, GMRS is covered by this section of the rules. Home based stations are not licensed to operate from their home location only. -
Over use of call sign announcements on GMRS

Well, I will state that 10 years as a Part 90 frequency coordinator issuing frequency assignments to business and public safety licensees and working directly with both the Wireless and Public Safety bureaus states your interpretation is in error. Base stations are fixed sites such as E911 centers and EOCs, commercial radio and television stations and the like. Stations installed in police stations, fire stations and business offices and buildings are control stations. -
Over use of call sign announcements on GMRS
BoxCar replied to SvenMarbles's topic in General Discussion
There are no base stations in GMRS. There are portable (HH), mobile, and control stations. A mobile radio run from a power supply at a home is classified as a control station as its intended use is to contact other mobile stations or control a repeater that connects to other control or mobile stations. A HH is considered as a mobile. I -
Handhelds below the 100 MHz frequency are not really worth trying to use. They are bulky because of their antenna requirements and loaded antennas (which are the short ones) don't work well because they don't have the bandwidth to cover the entire band.
-
If I were you (and I'm not) I would just put aside the idea of getting a 10 meter handheld and improve my 2M 70cm transmission and reception by focusing on better antennas and mounting. You WILL disappointed with the 10M handheld.

Bridgecomm's code plug isn't good for much more than connecting to their hotspot. It has no repeater channels but local to them IIRC. Other than as a starting point, it isn't worth anything as virtually the entire plug is copied from places like Brandmeister and RadioID. "

Don't waste your time or money on an HF HH. Bite the bullet for a true HF base or a "shack-in-a-box" radio. General is almost as easy as Tech and it opens almost all the frequencies. Check with a local club before making any purchase, but don't overlook used radios. There are some good deals out there if you know what you want and can be patient. I bought my HF with extras for about $300 less than new. "

DMR is digitized voice and reception depends on if the D to A decoder can receive the digital string with enough good bits or not. So, it's an either/or situation. You either decode the voice or you don't. The advantage is there is no fading as the transmitter moves away from the receiver.
-
There are 9 DMR repeaters in the area also.
-
Just to clear some confusion, channels and frequencies are often interchanged but they are not the same in all cases. A channel always contains a frequency - GMRS is an example. Frequencies can be assigned to a channel but they are also free-standing. In the amateur world we talk frequencies, but use channels when any other service uses them.
-
But you need your call sign before using the site. You can use the ARRL website to find local clubs and they often list repeaters and nets on their sites as well.

The lead VE will be the one to set the camera placements. I've never done a remote test but I've done about 50 in-person exams. l
-
Just remember that you will need 2 (two) cameras to take a remote test. One on you and the other on the work area to ensure you are not getting help from some place.

The 1701 is unlocked also.

To throw another fish on the pile, use of personal radios on a ship require the permission of the captain.

GMRS relies on line-of-sight distances like all radios using the VHF and UHF frequencies. The only way to have contact between your two locations is through a SINGLE repeater that both locations can reach. Almost all GMRS repeaters are owned and operated by individuals and their availability and coverage areas vary widely. Most GMRS repeaters also do not have emergency power or if so, it is limited to a few hours of operation. You may want to research amateur repeaters for their coverage areas and their networking methods. Ham clubs in your area can provide the information you need for your decision-making on both GMRS and amateur radio.

If you are licensed amateur there are lists showing which countries the US has reciprocal agreements with regarding operating privileges. There is an official notice along with your license you need to carry with you also. You may need to get an Icelandic call sign also while operating in their country.
