Hello
### There is also some information in a post from Dave G3YXM here
(uncluding photos):
https://klubnl.pl/rsgb_lf_group-archives/html/rsgb_lf_group/2018-10/msg00087.html
He says it's 50W.
### I see it mentioned here:
http://sp7pki.iq24.pl/default.asp?grupa=165822&temat=441483
Someone was looking for documentation. The response from SP9IKF is:
i don't remember the exact model, but most of these devices from RADMOR
and later UNIMOR were installed in Polish shipyards, and they must obey
the parameters in the SOLAS convention:
50W output
410-512kHz
A1A and A2A modes
-24V DC power supply
The TX is driven from a crystal, maybe the later versions were synthesized
but i don't think so. Generally it's a device designed in the '70s, the
device is completely transistorized. This is all that i remember.
The reply from SP3HSZ:
Thanks for the info. I could use some technical documentation. It is based
on a crystal, and works very close to our band. Looking at the PA i think
it might be capable of more than 50W, but i don't want to run it without
the docs.
You could try on elektroda.pl (general electronics site) and
sp7pki.iq24.pl (but this was already mentioned and not much information
was given).

Subject: Polish MF ship back up trasmitter
Hello Jacek,
Chris, 2E0ILY here. I hope you do not mind the direct e-mail?
I just got hold of an MF transmitter made in Poland by Unimor. It's
possibly an NR-2502 model, Type 2511/2, all transistor, probably
about 50W output crystal controlled switchable frequencies with auto
emergency distress keying on the emergency channel. I have found
very little info on it, and would especially like a schematic. I
wonder if there are any speciality Polish groups that might have
someone present who has such information? Thanks Jacek.
