Ok  search and google failed me. I have an opprotunity  to  place a bid on a  pallet of two way radios  from a school district. Other than setting up a base and  having a two way network of my own any ideas  what these could be  used for. what more info  would i need to get, how  do i determine  what range they broadcast and recieve on ?  they are mostly  midlands  I ll get the  model #s if it  would make any  differance. There is like  20 on a pallet and  im  thinking they wil go cheap. Right now I do not have any ham certs  but ive been wanting to if these are able to be  modified or  somthing it might  push me into getting my ham.  thanks  guys sorry  for my ham ignorance

we will need more info, a pallet of radios could be anything, they could be MURS, FRS, Ham, amongst other things....

thank you tesla what info would be on the radio that i could  give you all as I do have the opprotunity to handle them before  bidding. They were all used  on  busses  and  district support  viehicles. I  will bring  home some examples of  model numbers and post that after work (I work swingshift).

model numbers would be best, if you talk to them ask them for any information they have. its possible they could be programmed to work with what you need
 






ETA: also it might be worth just buying them and selling them off individually, but you might get stuck with a pallet of radios if you take that risk

Ill post model numbers tonite but  what im  curious about is the preamps and  such can they be  canibalized as I know they are well over 4 watts  If  they could  work as a mini linear (all legal  requirements being met)

Even length of antenna would be helpful.  Finding out what band they're in would be a good first step.

freq would be nice as would make and model number. as for setting up your own "network" you will need to either pay for a license or build your own repeater which still requires a license. im sure you can find all the info on doing this on the web.

The only info I can find so far lists them as 150-174 mhz and 110 watts.  I don't know if you could program them for 2 meter ham or not.  They could do MURS but it seems like a shame to use 2 watts on a 100 watt radio.

Most 100w radios will not program for low power, the high power amplifiers get unstable at low power levels.

If they are only spec'd for 150+, it would likely be a challenge (if not simply impossible) to put them on amateur frequencies.  

It would appear that this model is not narrowband-capable, which is probably why they are being replaced.  After 2012 all the commercial LMR stuff (on VHF and UHF) is supposed to go to narrowband... so unless it is capable of being used on amateur freqs, it becomes an expensive weather radio receiver.

I wouldn't drag them home.
