Weak, readable.

Thursday is 1000/1020/1040z intercept day.
If conditions remain quiet there's a good chance of passable copy.

Noise? BHI DSP Unit is the answer@

Well received!

Good Heavens! So have I!

So was I!

It's official; my talk at Bletchley Park 'Spy Messages 1950 to the Present Day's was well received.

Had I been there I would have bought you a drink. First sight, cracking volume.

The keyer shown in Aus Spy Mus pic punched message into 35mm film.
Reloaded, and spring driven, the resulting punch outs were read.

The radio schedule is here, seen in a standard sized petri dish gives some idea of small size (for concealment).
For message reception Lonsdale's sched was the same as Kroger/Cohen's; the header would indicate recipient.

This is the keyer. 240WPM

You sure about the transmitter? This is the one fielded by GCHQ. MI5 had another in less than good condition.
June 26, 2025 at 6:14 AM
I found the display of Portland Spy Ring transmitter/receiver very disappointing; especially when GCHQ have an almost pristine example with its rapid keyer unit.
June 25, 2025 at 2:38 PM
To finish the mocking correctly they show the world and its wife how to construct a bomb as MI5 exhibit
I was part of the upset. Chased off from US Embassy in Guyana by goon with rifle I was called on cellphone to attend carrier's office. Met by bloke, saluted me and called me sir. 9th August 2006.

Top in progress, Illegals next.

Snap! Sadly less a pint....

Have no fear, us Brits are here!

My eldest daughter now has a BYD EV. Very nice car, it records speech, your conversation appearing on screen. The card mentions emmissions (I'm a radio amateur) on the front. My daughter sees fit to add, inside, 'Like the BYD you're always listening!'
Intercepts a speciality

At National Archives, Kew. MI5 exhibition was very well done; however, one question is the staten of Kroger's transmitter/receiver. (Portland Spy Ring). Compare to other images from that held by GCHQ. No encryption device/burst sender device either. Wonder why?

An interesting 'talk.' A pint after at the station; 30m wait after missing train.
