Old SEA 222 aus HF Radio

UNLOCK SEA 222 aus HF RADIO

Hi I have an old SEA 222 aus HF Radio , wondering if Mike Johns or any one might have the U.S. EEPROMs or software to unlock the scratchpad memory for programming of freqs , would really appreciate any assistance with this old chestnut , cheers John .

 

I had a SEA hf radio as my backup radio. I don't remember having a problem programming in additional fregs They do need a special chip/circuit board to be able to transmit on the Ham bands. The company is still in business last I heard and they might be able to help you out. I think that the company name is SEA DATA. I used to have all of the manuals and schematics but they went with the radio when I traded it away.

 

Thanks Chuck appreciate your help , the Australian radios are setup a bit more restrictively than U.S. versions , but likely the same chips that open the Ham Bands do the job , cheers John
