Hi Everyone.
Just managed to acquire a Codan Type 7515 SSB Transceiver. Its a little bulky, all metal construction and appears somewhat antiquated.
The antenna is about 6'4" long, coated in, what appears to be, a brown plastic skin. There are 3 holes progressing up the antenna marked .110, 5300 and 5885.
Its sat in a blokes shed for the last 15 years, complete with God knows how many generations of Red Backs and only cost me a bottle of Southern Comfort.
Before I get our local radio repairer [burglar] to check it out, can someone please tell meif its actualy a
HF radio and if so suitable for 4x4 use.
Cheers.....Lionel.

Lionel,
Yes it is a
HF radio receiver/transmitter and is at least 15-20 years old.
In their day they were one of the best available and are still usable provided that you can use the frequencies fitted (5300 and5885), or fit your choice of frequencies.
You will have to find that out from an expert on HF gear .
The aerial sounds like an old multi frequency unit as those "holes" allow for different frequencies to be tuned using a 'snake' (That's what I called it,) a cable with suitable plugs fitted to plug into the lowest 'hole' on the aerial and the other end plugs into your chosen frequency 'hole' on the aerial .
I'm sure that others with more knowledge than me will be along to help on this site later.
Hope this helps.
Disco.

It's probably an old RFDS HF. Do you know where it came from? 5300mhz is the RFDS in
Derby.
How many channels does it have?
It will be crystal locked so you will need to change the crystals and the antenna. You should take / send it to a HF refurbisher.
This guy will know about it and how much to get it operational if at all.

Hey Bb2.
Yup, picked it up in
Derby, the blokes dad was involved with the RDF many years ago. Wasn't sure if I bought an HF or an antique paper weight but the price was right.
I'm amazed you could tell that from my post, great stuff.
Cheers.....Lionel.

A refurbisher to me would be Codan direct as there are a lot of things that I believe external fitters cannot do.

Hmmm...... to be a drag :-o)........it will cost $ for parts and labour to have a technician set it up for the frequencies you intend to use. The antenna may be 'the thing' though, in that a tapped whip antenna with matching lugs will cost very good $ (though a piece of wire hung from a tree will do). The cost of getting this unit set up for current day use might be unwise - a used modern day unit with selcall etc. can be had for reasonable $.
That said, an early crystal HF (but already having the frequencies and importantly, the antenna) can be a great machine - I had a Tracker Scout quite a few years back - a great performer (but no selcall) - sold it for $500 with it's Lencomm antenna - probably worth about a slab these days.

I would give it a miss, old Codans are hard to get parts for, they have limited channels and can be expensive to re channel and I would say this radio has no selcall making it useless.
Not even worth the effort even if it was given to you.

Yeh agreed.
The cost of the new crystals and the labour in realigning the set to the new crystals is not really worth it. I sold an old 7727 (an upgrade on the 7515) a few years ago for $80 with about 3 VKS737 and 3 RFDS channels fitted. But without the channels already fitted, the cost is not worth it.
The
Derby channel works very
well in the
Kimberley, but RFDS don't do the regular skeds like they used to, and if you don't have an emergency call button, you'll get little response in an emergency.
But they were a damn good radio in their day - but like a 30yo old Mercedes, one has to draw a line as when to decide it's not going to be the reliable thing it once was.

The 75 in the type means its a 1975 model which makes it 34 years old.
If you join the Codan users group
HERE, you will be able to find out all you will need to know on how, and who can get it working for you.

Hi,
I would not bother with Codan, they will have long ago stopped supporting a 1975 model.
To change the frequency you will need to purchase the appropriate crystals, people still manufacture those.
What will be the problem is the oscillator boards they fit onto.
If you wish to join the VKS-737 network log onto their site
http://www.vks737.on.net/
and send them an email and they will let you know where the boards are available (if they are). If you can get that working you will have to chase up a new whip antenna to deal with your new frequencies. You could try
http://www.outbacker.com.au/
Cheers
