Just got given some radios

[mcrover]

Hey folks,

My oldman just gave me some Ex Ambo radios and Im chasing some info on them.

Im pretty sure they are UHF but not entirely and I dont know if they are programable or usefull as Cit band UHF.

Ok this is what I have :

1 X Syntrx, Model # ATT32WOA7G00AK
It has no face, all the controls and the channel display is on the mic/handset.( I havnt tried yet )

2 X Sawtron KG107-15B25KW (I think)
These are remote face with key pads on the face and the handset/mic.(1 works, 1 doesnt)

These are the 2 that I am most interested in as we use key pad handhelds on the golf course so if they could be used there that would be good for the tractors.

2 X Phillips FM200 (on the remote face) and FM92 on the box.
These have remote faces and channel changing buttons and display on the handsets.(not working at the moment)

I dont know if they work or any more about them so any info would be usefull.

If someone can give me a hand getting a couple going, the others will be up for grabs as well......of course to the highest bidder :D

[Shonky]

Not ex St John Ambulance by any chance were they?

[mcrover]

Nope, a couple were from qld rural ambos when he was up there and the other 3 came from one of their techs when they changed their systems when he was based in Stawel.

There's good news and bad news. All these radios are unlikely to be UHF, the KG 15B is apparently a VHF high ( 150-170 mhz) so the others are probably the same. There is a some use for them in various areas, but not for CB. All of them use a eprom to store program channels. Of the lot, the syntrx is the more powerful and useful. The bad news is finding an eprom programmer and writing code/ finding program for it. The word hens teeth comes to mind.
Of course I could be wrong on what the others are, so find your local radio repairers and gently ask them.

G'day Mcrover,

I'd tend to agree they are more likely to be VHF. The FM900 does have a few different versions (VHF Lo, HI and UHF). If it is the VHF version it is of interest for Ham radio operators as it is easily reprogrammed (flash EPROM) to 2meters (144Mhz) also the LROCV have a VHF freq (150 something Mhz) and FM900's are suitlable for that freq also. All tuned up they sell for about 100 to 150 bucks but as mentioned above you have to find someone with the gear to retune it - I can put you in touch with a ham radio club that has done heaps of these and may be of help.

Cheers

Ok, research last night I found that the Sawtron units are regarded as the cream of the UHF and is a 25w unit from the model number.

The Syntrx didnt bring up anything of interest and the Phillips units are said to be reliable but not much more than that.

There are a number of different versions of the Sawtron units ranging from VHF though UHF and even an HF version and the model number is the key to it all.

The model numbers on the units I have says they are Rural vic ambo set up but apparently are reprobramable with a change of Eprom.

Apparently they can be wound back down to the legal wattage that of course I will do.:angel:

I just need to find someone who will program me an Eprom now.:p

[rover4life]

You will have to find some 1 that can rewrite an eprom for the philips i have a vhf 1 in the shed tuff reliable radio. look at the silver plate and read the freq number will tell u wat freq it is also the sawtron will need an eprom same as the syntrx also sounds like probably a vhf network prob no real use try selling ebay might make some cash:)

All are 400Mhz apparently.........forgive my ignorance but is that VHF or is it just ambo stuff only which is no longer in use.

400MHz is in the UHF band, but isn't CB or Amateur. There is a lot of commercial stuff in the 400MHz region, so you'd need to look at the exact frequencies it has fitted and match them to the band plan from ACMA to find what they were used for.

I know they were Ambo radios but im trying to work out what the hell I can do with them.

They are too good to just throw away.

[Sleepy]

Yeah all UHF.

Amateur (70cm) UHF is 433Mhz (approx) and UHF CB is 477Mhz.

Lots of Ham radio guys use commercial equipment on 70cm but may even be able to tune it to 477 and use it as a CB.

Your right though, most commercial stuff is of higher quality and too good to throw - Just gotta find a use for it!

I got onto a guy in Adelaide off another forum that said it's possible to convert the Philips with a turn of a pot and a new Eprom but the problem being that I need to find some one to do it.

The Sawtrons are apparently a different story as it is apparently built into the board what they are designed to do with very little adjustment available other than Eprom program within the range that is built in.

Oh well, something will come up one day and I will pull them out from under the bench and dust them off.

mcrover,i will take the sawtron thats not working off your hands (for parts )if you like.you can contact me 0422815611 be aware with commercial radios,they might be built more robust,but because of their higher output,they run alot hotter.in cars and trucks their ok but start knocking them around offroad and they can sometimes be troublesome.eric

Be aware that if they are VHF they are probablly private frequencies purchased by the ambulance service and it is an offence under the telecommunications act to transmit on them. The majority of VHF frequencies are just that user pay, bu there are some free to use frequencies such as boating channels. VHF wont be a lot of use to you in general if they are set up for private channels. Of course you could buy your own channel, but it would be restrictive.
A good tech will be able to reprogramme them for you to suit.
We use VHF at work as private trunked channels.
We use a company called Commsource.
The 25w UHF's sound like the goods.

i currently have 3 motorola,s (syntrex) 1 operating as base two in security patrol cars are very reliable but geting hard to find parts for mine operate in the 477 mhz range private freq have also had fm 92,s they work well also same freq all of yours are come in a range of freq so you need to check use google and serial number should be able to find all info you need all should be 25 watt and if came from same source should be same freq. if rural ambo,s could be either vhf or uhf vhf has greater range.any radio shop should be abl to look after reprogramming the phillips and motorola sawtron not sure about.hope this helps
