Howard,

I am trying to make my SEA-235 radio work easier with digital modes. It is a marine receiver, follows very closely the nmea marine format but it has some differences, such as a different way to calculate the checksum and a more extensive command set. Would be interested to help with integration in HRI?

Just to give you an idea where I am in the process, for Winlink, I created a python file that takes the Icom marine commands, replaces them with SEA commangs, recalculates the checksum, then outputs to SEA. The reverse for the status information. It works and it is neat but still a pain. For FLdigi, I started with the conversion of the IC802 command set but the Hamlib implementation is buggy and it breaks down. Next I took a stable Hamlib driver for a Kenwood amateur radio and translated that using python scripts. It is still a pain because amateur radios have a different approach to marine radios. For example, I have four AGC settings that I like to use on my radio, Kenwood supports only two and they are not like for like. I have a full description the the command set.

What do you think?

Regards,
Vassil?

Vassill,

I can see the possibility of adding the SEA-235 radio to the visual studio version of HRI. I would feel better if there were dozens of people asking for it.

Adding a radio which I do not own is a long tedious job. There will be dozens of test versions which will not work. I recall with the 710, I would often have to wait days for the tester to go to his boat to test it.

There have been cases in the past where someone wanted a radio added, but would not put the time necessary.

You can email me directly at Howard_Z at Yahoo.

Thank you for the response. I think for now I will stick with my emulation approach, where I set-up fldigi to Ray 152, then use Python to do the conversion. After spending a couple of nights tweaking it, it seems to be working quite well. I will continue testing and cleaning up the code. Once satisfied I could share the python file with the group and I believe it would be fairly easy to make the change.

Thank you again,
Vassil
