Ahh yes, I see the DX-440, I still have mine going strong after all these years.
I still have all the rest of the gear, including the 30+ year old Heathkit 'pixie' freq counter, FT-101B, and the audio filters, keyer, etc. from the photo.
I have been a SWL since I took over my Dad's Zenith Transoceanic back in the early 70s. I have since lost them, but back in the early 70s we got qsl cards from Radio Cairo, Deutche-Wella, HCJB, VOA, and many others ... Learning to pick the wheat from the chaff (signal from the noise) while tuning up and down a SW band is an art form.
