More R/O video clip nostalgia.

Takes one back !

Interesting the Mimco gear on Liparus to the British Adventure both types I experienced on my PMG course at Leith Nautical and also at sea..
Mk 1 Oceanspan and CR300 receiver plus Type M Auto Alarm seemed all that would ever be necessary in those halcyon days !!

The CR100 and 300 were sweet, solid and steady - the Redifon R50m rx wandered a bit. The Siemens SB186x transmitter (it was common on Brocklebanks) had a nasty r/f bite if you touched the coli tuning bar while the key was pressed. But it was all we had - except for oddities like the Brocklebank 1940 rx, built in the shed at Liverpool by r/os rescued from torpedoes.

Hi Harry,
My nostalgia kick for today. Almost got a full house on Malakand/GOFP: Redifon R50M drifting - check, copying traffic with left hand on the tuning knob to follow the signal; CR100 - check, preferred it to the R50M; Siemens SB186 - check, R/F burns from the PA tuning bar and exposed screw heads, also polishing the brass bits on the front panel; Type M auto alarm - check, twiddling the knob a few times to get the motor started.
I don’t recall the model number for the D/F. It was a Siemens swinging loop suspended from the deck head in the chart room - made you feel like a u-boat commander standing under it and turning the “steering wheel” to take a bearing.
I never sailed with the Brocklebank “biscuit tin” receiver but did have a later Brocklebank-made RX on Mahronda/GDNB.
The dockside shed was an Aladdin’s cave of ancient equipment.
Happy days

PreWW2 build GTZB ships that survived the war were updated late 40's early 50's mostly to Redifon and I have to come to the defence of their R50M receiver in that I don't recall having any serious drift problems or did I with the Mimco CR300 specifically designed for MN ships as it only ranged to just above 22 mc/s and esialy recognisable with its cabinet loundspeaker..
My only criticsm of the R50M compared to the CR300 was it's feeble logging scale design..

I am glad somebody else didn't think the R50M was all that bad a receiver. I had one on a Harrison boat in 1956 and did 2 trips with it with no complaints. perhaps they didn't age well.
