Unlock code for SEA222 SSB Radio

Eric, Thanks for the quick reply. I had assumed the damage was to the keypad and had not thought of the PCP. Will check. I worked out the pinning and did some shorting. Keypad 1 and 4 work and right column. It is a nice looking design and showed no moisture damage so I didn't think of the PCB. Will let you know what I find. I am repairing it for a friend and don't know if he has an ant tuner. Thanks so much. Sid

 

Eric Thanks!! Radio Fixabel. Board and uprocessor are OK. My new keypad had different pin outs so I used 2 4 pin computer cables to connect it to pcb. After checking pcb I looked at cables. One had only 3 wires and the other had two wires connected together. New keypad didn't work well!!! Original radio keypad all open so something odd happened to burn it and the flex cable. Problem now mounting keypad etc. Thanks so much for inspiration. Sid

 

Eric, Thanks for the help. The radio is fixable. The pcb and uprocessor are good. The key pad I purchased had a different pinout. I used two 4 pin computer cables to connect it to the radio. I discovered that 1 cable had two wires commoned and the other only had 3 leads...Keypad did not work well!!!-My problem now is the mounting and connecting of the new pad. The original pad along with its cable is NG. Very wierd failure, melted. TNX again Sid

 

Iv'e used a keyboard available from mcm electronics on a couple 222's. I just mounted it to the front panel after removing a section of the old keypad and painting the housing first. Here's a couple pics.

 

Eric, Thanks for the pics. Better looking than my job. I did not cut slot in panel. I spaced out the keyboard to make room for the connector. Did the keyboard come with the correct nominclature or did you apply it? If so how? Anyway the radio is fixed and works just fine. I am 76, had a First Class telephone licence in 1950 but those days are long past. Sid

 

Here's the original keypad available from Jameco. I changed the bottom row and the right button on the next row up. I just used a graphics program and printed on label paper so it just sticks on over the keypad buttons and then I applied a piece of clear self-stick paper over the bottom half of the keypad as you can see if you look closely.

I too have a SEA 222X with the scratchpad locked, can you send me the Bin file please!

 

Are you still working with SEA 222X radios? if so I would dearly like to ask for the Bin file to unlock the scratch pad and also to find out if a pactor modem can be wired into the SEA 222X - looking at the original manual I think it can be done, and they indicate so with a low level audio feed pick up point, but would welcome advice.

Help with SEA 222 SSB please!

Hi All,

I know this is an old thread but I'm hoping someone with a SEA222 is still watching it.

Problems is my bother is sailing in Vanuatu and having trouble with his SEA222. But, I have no radio experience and it's difficult to communicate to him via text message (at the moment he is out of phone coverage.)

Question is, for an SEA 222 SSB what is the exact key sequence needed in order to get into transmit mode for frequency 4003 kHz?

From the brief cell phone messages he was able to text me, I believe he can successfully get the SSB into Receive only mode for that frequency, but can't get it into Transmit mode for that frequency.

He's not sure if it's a technical problem or if there is just some special key sequence to get it into transmit mode for 4 digit frequencies. He tried but was not successful entering the following key sequence:

4003, then hold down the mic button, then press ENT key, then release the mic button.
​

For that sequence he confirmed that no error code shows (and I think it just clears the screen as if it wasn't valid).

He indicated that he can successfully get it into transmit mode for higher frequencies, but I'm not sure which ones.

I'm waiting until he reaches Luganville to have phone coverage again. I'm really hoping that someone who has an SEA222 can confirm the correct key sequence by entering frequency 4003 kHz on their radio. (e.g. Maybe he needs an extra zero after the 4003 so would need to enter: 40030 mic ENT release the mic?)

Thanks heaps for any assistance on offer!

 

Do you know where the radio came from initially? They have differently programmed frequencies depending on region. I f It's an Aus version I can go to my boat and lookup the user manual for you.

Most likely its a duplex frequency so you Tx and Rx if different channels.

Curious as to what's on 4003 ?

cheers

Hi
I have the original manuals for a SEA 222X - which has a slightly different keypad operations coding than the SEA 222 .. and most importantly are you sure you have an open scratchpad that allows you to programme any channel?
i can be contacted via pcmcb@xtra.co.nz

 

Hi Mike,

It is an SEA 222 AUS model like yours.

I think 4003 kHz might be a weather net. My brother said they operated starting at 7am Vanuatu time. (Yes, not certain it's simplex but not sure how to check.)

Yes, please, it would be very helpful if you could check your manual and ideally enter the frequency on your SEA to confirm the correct key sequence.

Assuming it was simplex, would he needs to enter:

40030, then depress the mic, then press ENT, then release the mic
​

...to get 4003.0 kHz simplex operation?

 

Hi Peter,

That's a good question but I'm not sure. Is there an easy method to check?

(Keeping in mind I'll have to text him the instructions to check.)

Cheers,
Keith

 

Hi Peter (and for the benifit of anyone else who might be able to help),


I just checked the text messages from a few days ago and my brother did confirm that he could program channels into scratchpad for higher frequencies.

Does that mean he has an open scratchpad or are some models of the sea222 locked for certain (lower) frequency ranges?
