• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

Hi All,

Codan HF 4000 modernization, has it been done? Bypass of channelized EPROM, direct control of frequency, sweep functionality, pc interface?

Around ten years ago I intercepted an HF4000 set just as it was headed into a dumpster - my lucky day! I had only recently received my amateur ticket and had not yet invested in an HF radio.
It was complete with HF 4101 Head, Microphone, 200W PA and ATU. 24V version.
Hooked it up, turned it on, flicked through some channels and in came a weather bulletin, loud and clear - I was pleasantly surprised, to say the least.

Of course I quickly discovered, sadly, that this generation only had the capability of 256 channels via EPROM - no free tune.
I had a lot going on, so it has lived in a box for a while now!

Recently I have wanted to get some projects off the page \ out of the mind and into reality - way too much "junk" lying around that has been perpetually earmarked for projects that never realize!

Any advice?
It seems criminal to let such a relic go to waste - it just needs a new brain! Arduino?

Cheers
