They would be built for a specific frequency.

11 meter is the CB band. 10 meter is a popular amateur band. Due to frequency propagation characteristics, it is well suited for long distance communication. That is why a lot of CB users will run a linear.

It has been years (more than 30) since I played with linear amps and radios. The older equipment had tuning crystals and coils where the frequency could be optimized for peak performance.

You may be able to find a web site listing the equipment you have with some specs to determine if it is tunable.

My use for the FMRS and CB is for listening in on larger contractors, whom use the said equipment to stay in touch with eachother across a job site. Now that I've installed my Cobra 18WX-ST, I can listen to the NOAA weather broadcasts, and spy... <img src="/forums/images/graemlins/rodent.gif" alt="" />

I run a Galaxy 949 tuned and aligned, 100% modulation, swings to about 16 watts from a 1 watt dead key. This is up through a Wilson 5000 mag mount antenna. Its a little tall, and bangs the low trees, but it doesn't hurt it none.
I can't see the use of a linear on the trail, this is kinda overkill. I hang out on a Cb radio forum as well. A linear is fun for talking DX when the conditions are there, thats about it. Also illegal on 11m band, not that thats much enforced anymore. Unless your throwing around 10k watts on a base or something, the FCC doesn't care much.
Just my little well tuned system talks great in a 10 mile radius or so, just fine for trails/ highway. Way better off trail too then line of sight FM units like FRS/GMRS. If you guys want privacy and the audio quality of FM, MURS radio is starting to pick up. Its a little pricy, but no need for FCC licensing. This is my second hobby besides trail riding. I do hope to get my amateur license someday, but got too much going on right now.

Got a question here concerning scanners:

First of all it WAS my Passion and HObby, As well as my club that I was with....Long ago.

We would listen to even the school bus route on the net and even UPS (I know get a life) <img src="/forums/images/graemlins/lol.gif" alt="" />

About 20 yrs. ago I had a really nice mobile scanner (it covered most) if not all of the frequencies <uhf-vhf-television-> As low as 18 to 600 .....My memory is bad....but it was a really nice unit!

Used it while I was in N.Y. and even took it to Europe{might have been illegal <img src="/forums/images/graemlins/ignore.gif" alt="" />}!

When I look at the new ones today they are in the area of $500.00 ---- $1400.00 BUT they have limited or restricted some of the frequencies???

Or am I not looking in the right area???????

They don't go to the GHZ or do they?

I remember 49.0 MHZ was for the old wireless home phones and such and 70.0 MHZ was for the military Base security overseas (130 stateside) etc...

234.0 was like for the old school Law Enforcement...

Anyway, have the scanner laws changed?

And 800 mhz was like trunk-ed systems etc...

It used to be a nice hobby that I had before to listen to the aircraft and what not........But did the laws and production of units change besides price?
Am I on drugs or did the older units allow for more freq. coverage????????

If this is confirmed then I should be looking for used older models right?

SIDE NOTE: While I was in militry in GE The german Police asked me what our frequency was (On back of my radio) and I said 71.4 and they dialed in on a mobile unit in their van and keyed the mike and they were on our band (no encryption active ) of course! <img src="/forums/images/graemlins/kewl.gif" alt="" />

BTW: I got a CB but would go otherwise if my friends did too! <img src="/forums/images/graemlins/cheers.gif" alt="" />

2nd question:

Awile back I bought 2 old taxi transceivers with amps in L.A. from the flea market (prolly from Mexico)....Never used 'em but what if I did?

Would that be illegal?

Thanks y'all

Mike

P.S. I voted and have a piece of crapp mobile CB <img src="/forums/images/graemlins/barf.gif" alt="" />

I don't recall it being passed as law....

However, several years ago there were some FCC rules that locked out cell phone frequencies from access by scanners.

So, your observation of older scanners having more freq coverage is probably correct.

While some radios have gone up, others have come down. It is now more affordable that ever to move into 2 meter.

Depending on the taxi radios, you may come up on an previously allocated frequency. That would be bad news if you tied to use them.

And, yes it would be illegal to use a radio in a requency not allocated for that use.

Thanks for that super speedy response (ALmost as fast as the KIA Sport Forum)! <img src="/forums/images/graemlins/kewl.gif" alt="" />

What scanner models cover almost all of them?

Just may get back into it again! <img src="/forums/images/graemlins/patriot.gif" alt="" />

The 2 meter band would be nice in my case at home (as a base station prolly)! <img src="/forums/images/graemlins/kewl.gif" alt="" />

.....More: Just supose that I used those taxi radios --- (suppose) then would not those frequencies be allocated for CA and not TX?

I mean wouldn't it mean that the frequency was meant for that area an NOT if I used it in TX?

Just wondering?

Thanks

Sorry for posting again: I got it now!

Thanks <img src="/forums/images/graemlins/cheers.gif" alt="" />

I have not kept up with scanner capabilities since I left the Navy over 30 years ago and worked on some of their radio frequency scanners.

You might try a google search on radio frequency allocation or RF band plan

And, the FCC web site may have some of the info.

From what I have been reading, frequencies are allocated for commercial communications based on location. The main point would be to limit potential for interference within a normal operating environment.

And, there is a lot of frequency sharing happening in some areas.

The military has a number of frequencies that are allocated. As do public safety agencies.

I am trying to come up to speed on the latest changes in ham radio equipment.

Yeasu makes a good radio that covers 40 MHZ up through the 800 MHZ range.

I would like to see this in my search....If it is then WOW!
(New territory)...
K and thanks John!

Will certainly check! <img src="/forums/images/graemlins/cheers.gif" alt="" /> <img src="/forums/images/graemlins/patriot.gif" alt="" /> <img src="/forums/images/graemlins/kewl.gif" alt="" />

Thanks for helping an old Dog of radio (Scanners only) though.........Thanks for INFO! <img src="/forums/images/graemlins/kewl.gif" alt="" />

Keep in mind, there are still "cell phone blocked" frequencies.

Take the plunge to 2 meter. It is superior communications....
