On 28 October Malin Head Radio (51N – 19W) was heard working a distress on 2182 kHz.
Greetings from Malin Head. I read with great interest a note in the events during Awarua Radio ZLB and the following: “On October 28 Malinhead Radio (51N – 19W) heard working a distress on 2182 kHz.”
I made a point of checking the distress records for our radio station for that date and can confirm that Malin Head Radio did indeed work distress traffic. I noted that the position given was 53 North and 19 West. This is an amazing bit of watchkeeping and must be the furthest distance for our transmitters, of the time. At that time we were using Pye transmitters, with a 5CX1500B valve in the final, running compatible AM with 500 watts carrier. We later changed to USB in the following years and ran 1 KW from SPT gear, replaced by German transmitters about 5 years ago.
The antenna was, and still is, 150 foot masts, one for 2182 kHz and the other usually used on our working frequency of 1677 kHz. The original 500 kHz Tee antenna strung between the two towers is used on Navtex on 518 kHz and 490 kHz these days.
Personally, I retired just over two years ago, having completed 34 years at EJM, and a further seven years before that at sea as a Radio Officer.
Really enjoyed your website. I am particularly interested in 500 kHz, stories of such, and recordings also of 600m/500 kHz.
Very best regards,
Finbar O’Connor EI0CF and ex EJM (GMH)
