Indonesian Navy P5O 3.635MHz CW
« on: July 10, 2017, 2241 UTC »
Came across this new logging last night on 6.365MHz CW:

" V V V V V V V V V P5O P5O P5O 1/2/3/ K K K"

It's Papa Five Oscar (not zero) at a good steady 569 report sending over and over for around 15 minutes.

Can any one help ident this?  Possibly North Korea with the "P5" prefix?  ???

I went ahead and moved your post to the Utility forum.

This is the Indonesian Navy.  You will also find them on 12235 kHz and 18890 kHz.  When there is no traffic they send as you described, same callsign and format, but they do also sometimes send traffic.

Thanks for that, however, I went off the ITU International Radio Prefix guide which shows:

P5A - P9Z  North Korea

PKA - POZ  Indonesia

Will check out the other frequencies later... :D

Sure, but how often do you hear military stations that ignore the ITU International Radio Prefix?  P5O belonging to NK or not, this is Indonesia.

In the past when the station has traffic some of the traffic sent has been clear text, making the source (Indonesia) and the use (Navy) clear.

I left off a frequency, 9945 kHz.  I have it on 4 freqs in my logs, 6365, 9945, 12235, and 18890 kHz.

In addition to P5O the callsigns of 7CB and 7CJ have been on the same freqs, indeed all three callsigns have been in the same message body, although most of the times I have heard traffic it was the P5O beacon until the traffic starts, and then the P5O beacon goes away and the traffic starts with the 7CB/7CJ callsigns.  Once the 7CB/7CJ traffic is done the P5O starts again.  And the 7CB and 7CJ do fall in the ITU International Radio Prefix allocation for Indonesia.  Why they use 2 calls that are "correct" and one that is not I have no idea.

Most times & frequencies posted are only an approximation.
Due to adulteration of the E.N.I.G.M.A. "designators" they're never posted nor ever used.
