Either that or no one will talk to me

I have a Codan 9323 plus auto tune. It is installed in my land cruiser with good earths etc but I can't seem to raise anyone with it.

I am a member of VKS737 (Mobile 1745) and have tried to get onto skeds numourous times from all over NSW and Qld but can't raise anyone.

The thing makes all the right beeps and aerial tune noises and I can hear others trasmitting.

This is my first HF and I bought it second hand..

I need to get it sorted as we are currently travelling around Australia for a year and we will be heading into the more remote parts in the next few months.


Any ideas??

With the 9323 you can select power high/low. You havent accidently got it on low ?

Gooday Joff1,
The other possibility is that you have a cable fault..... you can still recieve ok, but on transmit it breaks down as that's when the power is applied. So thoroughly check your aerial cables and connections; one dab of solder or stray screening wire can spell disaster on transmit.
All the best for your trip.

Joff1

Call VKS on the phone and telll them your issue, and ask if you can call them on the radio while on the phone. They can let you know if they heard you.

thanks boobook. I have tried so many times to get radio checks from adelaide and charters towers without success. I have even tried to get them when I hear others just chatting.

I'll go through and check all the cables first and if that don't help I might try it then.

Have you tried beacon calling the base stations. If you get a revertive, then you know you are working fine.

So times when you listen to skeds, the base appears very loud. You cannot assume that your signal is as strong as what you hare hearing. Base Stations use a much bigger antenna so they have the capability to get out a little easier than your auto tune. But given the right conditions & frequency, you will be able to transmit a very good signal.

Oh, BTW, if you call a **99 beacon at a base station, you have to selcall the **99 number, not beacon call it.

Joff, the above suggestion is a great one. Selcall one of the stations beacons and see if you can hear the beacon come back.

Graham is on the right track. Stop fiddling and get it to a technician. You could be doing more damage.

Where are you?

What is your home / radio test location Joff ? I do some base skeds for the volunteer team at VKS737 - could suggest what you could expect from your location re comms - I could fire up a base at an agreed time to run a test.
The radios are extremely complex of course - only one small 'thingy' needs to be playing up for the operation to fail - some maintenance over the years is to be expected as I'm sure you know, but that said, they are also amazingly durable. Had an issue with my Barrett 950 though, at one stage - RX fine - Tx no good - back to the factory - and all fixed for a very reasonable dollar I'm pleased to say.

Home/Radio test location?

I'm on the road permenently at the moment so wherever my Cruiser and camper is parked is my Home/Radio test location I guess.

Would it make the jump from here to SA?

HF conditions vary all the time, but have recently been great. Airlee beach is too close to Charters Towers IMV for good comms but you should get into the Alice nicely. Adelaide is quite likely too - Perth is a bit far - I've had a caller or three into Adelaide in recent times starting at 17:30 hours CST, from right up the QLD coast. Summary ? IMV, if you can't consistently get into bases around + - 2000km away during a sked, when the sun is quite low (much better late or early in the day), then the radio needs to be checked by a technician if you have checked all of your wires. Better to be over-cautious if you are going remote.

A thought... Have you got all the cables bunched together?
By that I mean, power, 9350 control cable and co-ax? If you have, this could be part of the problem.

Thanks Footloose.

Stu, I'll be in Cairns is a week or 2. It's good to know there is someone there coz I'd like to bypass Townsville if I can help it.

The 2 cables that run to the aerial run together. The Power to the unit goes a different way as does the head unit wire

Are you running an inverter or fridge near your radio? These can affect transmission. I was involved in helping a bloke out with a motorhome equipped with an HF. Mine was working OK but he couldn't transmit. We finally found that shutting down his inverters solved the problem. I have heard some fridges and switchmode power supplies can cause problems.

No inverters etc but there is an Engel 60lt about 2' away on the other side of my draws. I doubt that would be the issue though since I don't think it would have been cycling every time I tried to use the radio. Unless just being plugged in is enough.

Fridges can interfere badly with Receiving but not with Transmitting.

Thanks for all the replies. On Stu's recommendation I shot off down to Miles Electronics in Cairns today. 2 great blokes came out to my Cruiser to have a bo-peep. They soon figured it to be a mic issue.

After an unsuccessfull attemp to fix it they fished through some old boxes to find a second handy. We were starting to lose hope when the first one they found had the same issue mine did, but the could see by the torn clothes hanging off me I wasn't keen on paying $290 for a new mic.

They kept searching and finally found a 2nd hand unit that worked a treat. About 45 minutes of rooting around and all they charged me was 50 clams, including the 2nd hand mic. I told em to double it but they would have non of it..

I'm 3x3 to Alice base about 20 minutes ago.

Huge thanks to the guys at Miles Electronics in Cairns. and thanks to Stu.
