[GMRS not FRS hand held]

Amazon sells a Btech battery for the Gmrs-v1.

Its 3600 mAh, and sells for $20. They also a battery replacement pack to plug into a vehicle accessory receptacle for $16.

 

Note: get the Bl-8 not the Bl-5

[Antenna for base in apartment]

Most magnetic antennas require a ground plane. The size is frequency dependent. Minimum size is about 1/4 wave length in diameter. 6 1/2 inches for GMRS.

 

I've used a cookie sheet with moderate results. Mount at a window in the direction you need to transmit.

 

Good luck.

[10 MHz Split vs. Filter Technology]

Thank you for that. It is a realistic and practical description of the situation. Also, just for the record, I hunt with a recurve bow.

[10 MHz Split vs. Filter Technology]

I was describing a legitimate use of gmrs radio. Not necessarily to pursue elk but to coordinate the recovery of a downed animal (up to 750 lbs after field dress. But also to "find" hunting friends who have become CONFUSED about where they are.) ( lost).

 

I was inquiring if this use of a repeater was legitimate as it is only used at camp.

 

Is a fixed location temporary or permanent?

[10 MHz Split vs. Filter Technology]

Im not sure if that would help the elk as they lack opposable thumbs.

[10 MHz Split vs. Filter Technology]

My hunting trailer started life as a 16 x 7 ft enclosed insulated cargo trailer with windows. Power is 4, 6 volt pallet jack batteries connected parallel over series. 4 100 watt solar cells on roof. 4K cummings generator with 40 gal tank. (Mounted on flatbed 1 ton truck ) Radios in trailer, CB and GMRS. GMRS is a $400 dollar repeater made from two Motorola mobiles in a suitcase ( ebay). Every one we hunt with uses Btech gmrs v1 radios or the Betech 82hp. Having a repeater parked on top of a ridge gives solid coverage to both valleys on either side. As this is a trailer it is not used while moving. I belive this makes it a FIXED location while in use. (Hunting elk western Wa. State.)

[FCC partial shutdown]

Hi, I just read an article on another radio forum. (E ham.net) The FCC is suspending most operations during the government shutdown. Most important to us is as of Jan 3, GMRS and Ham licensees will be accepted but not reviewed, and entered into their data base until after funding is resumed.

 

Thanks for listen

[Colinear antenna]

Your teacher was a wise man (or woman). The best part is I almost understand it.

[Antenna gain vrs. Bandwidth.]

Wow, again i show my ignorance. Its a good thing I'm not proud.

[Antenna gain vrs. Bandwidth.]

I've noticed a relationship between bandwidth and antenna gain. My observations are based on antenna descriptions by the mfg/seller of the antennas.

Example, an antenna described as a vhf 5/8 wave antenna will claim a 3 dbd gain. With a 6 MHz bandwidth. A 1/4 wave antenna unity gain ( same mfg) will be described as not needing a tune over 30+ MHz.

 

My question is: Does this relationship actually exist?

[Colinear antenna]

I love this web site because it offers me an unlimited opportunity to display my ignorance.

 

What is a colinear antenna?

Wow, i just got popular, mr. Berkinet, try again, i went into delete mode and ........well,sorry

The GUN issue, has no relevance in this Forum. Yes, I am a 2nd amendment advocate but other than FREEDOM I AGREE with you that you are free to express your views in any way you choose.

 

I eas inquiring in reference to your. Superior experience in technology.

[Hypothetical question of UHF antenna bandwidth.]

Love this about this web site. You and i are grumping at each other on a different segment yet talking on an other

[Motorola Radius M1225]

Wow, this topic accelerated it self beyond the level of this forum.

 

Berkinet PLEASE contact me on the side.

 

Thank you.

[Motorola Radius M1225]

It wasn't to be FUNNY. a difference in opinions is nothing more than a difference.

Two people will always have a difference about something.

Wow, are the thought police active here or what? I stopped addressing gun forums because people would get crazy. CHILL OUT!

 

I can start talking about radio controlled AR-15s if you really want excitement.

[Hypothetical question of UHF antenna bandwidth.]

If this topic violates any rules or is close, feel free to move it to the private forum.

[Hypothetical question of UHF antenna bandwidth.]

If someone with a ham license and a UHF radio, were to program the radio to include GMRS frequencies how would you resolve the possible 27 MHz. difference to tune the antenna?

(440 MHz to 467 MHz.) Understanding it would violate FCC regulations to do so?

[Part 95 Repeaters]

If it was Midland it would cost twice as much and only work "their way" instead of what their customers want.

Example 1, Mxt400 for $249.00

 

Example 2, repeater pl tones must match tx & rx.

 

Thanks for listen, Keith T

[Alinco Part 90 Radios]

Heed this Midland engineering.

[Alinco Part 90 Radios]

I get the feeling that Midland views mobile gmrs radios as a central radio to be used with their line of bubble packs. They even bundle them together. This also explains the limited options on their repeater capable units. Two major problems:

Inability to use different pl tones between tx and rx or even pl tone on tx and just squelch on rx.

No memory channels for different repeaters. (Different channel pl tone combinations.

As these options are avaiable on type 97 radios, its no wonder that people use ham radios rather than type 95.

Thanks for listening.
