Title: For those ham's out there...
Post by: Elsifer on October 11, 2006, 01:21:53 PM
Now, correct me if I am wrong, but when the stats on a radio state "HF/VHF/UHF All Mode Transceiver"; it means the rig can transceive on all freq's in those bands? And the band plans allotted in canada are up to the operator to adhere to?

Specifically, I'm reading the specs on the bling-bling Icom IC-7000 (http://tinyurl.com/h9rgq).

Any light clearing would be appreciated.

Thanks
Chris

Transmits and Recieves on all those freq

HF   - High Frequency (3MHz - 30 MHz) Shortwave Ameture Radio
VHF - Very High Frequency (30Mhz - 300MHz) FM Radio=88–108 MHz & TV & Marine, Plane Communications Systems
UHF - Ultra High Frequency (300Mhz - 3GHz) Satellite Communication and Broadcasting, Cellular Telephone and Paging Systems

Looking at the website you posted, looks like a nice peice of equipment. Tx from 3Mhz - 440Mhz. Rx 0-3Ghz.

Yes, you can transmit and recieve on all 3 bands.
The freq. allocations for amateur radio are the same in the US and Canada.
This radio would probably be way overkill for what you would need Chris.

All you really need is a 2m rig or maybe a 2M/70cm (VHF/UHF) which should only cost $200 to 300 depending on brand.

A good place to shop for radios is

 In NE calgary. just like everything else it is always wise to shop for the best price. They are usually very competive with their pricing.



Matt is in the right ballpark with his band info.
In the 3 bands there are certain frequencies you are allowed to transmit on.
VHF  You will generally see communications around 50 Mhz (commercial) 144 Mhz (2m)   136 to 174 Mhz for commercial, Some ham around 220 Mhz but very under used.
UHF commercial 403 to 430 and 450 to 470 and ham stuff around 70cm (you figure out the freq :D )  Cellular, iden, LTR trunked radios are in the 800Mhz area I don't believe there is much amateur communications in that range. There are some data radios (spread spectrum) used at 900 Mhz

The UHF band is 300Mhz to 999Mhz  anything over 1000Mhz (1 Ghz) is technically a microwave.

The HF I don't do much with, i know there are freq's used around 8-10 Mhz and I guess CB's at 27 Mhz are technically HF, but are not usually refered to that way.

I've got a 4 set of UHF reviever/transmitters that work up in 645MHZ-720MHZ   sweepable in 0.025 increments. Two transmitters on beltpack and two hand held units. Good up to 2.5 km's Line of sight. Powered by two AA batteries with a lifespan of 8hrs on fresh cells.

any guess what they are used for?

No. I have no idea.
That's interesting, I will have to look in to that

A guess: something with aircraft? search and rescue?

Edit:
2nd guess. to transmit audio and/or video from a recording device (video camera? ) back to a central location where it could be recorded to dvd or rebroadcast.

Bingo! you've got it Ian. It's my wireless micrphone system. Tranmits UHF carriers for the trasmission of audio frequencies. It's actually kind of interesting how it works. The tramitter generates an in audible pilot tone that the reciver locks onto, much like a digital handshake. Once locked on, it will ignore any other broacasting frequencies to ensure clean recpetion.

It's not nerdness, its Nerdular Nerdence!

Thanks for the info, based on what some Ham's told me from Eco, it appears that all that is needed for trail use is a higher powered 2m unit. So that simplifies things a lot for me.

Thanks all
Chris

You should be able to pick something up for 50 bones for trail use.
