Amateur radio is a hobby that uses advanced technology in most ways.
I have a special interest in radio equipment from WW2, and design of radio equipment with tubes.




Here are my ham radio cars.



Here are my lab.


FELD HELL

FELD HELL is one of the many modulation modes available to radio amateurs. It was invented by Rudolf Hell in 1929. It was used extensively in the press, diplomatic and military communication. The connection also works on bad radio or telephone lines. In recent years, the commercial use of FELD HELL has ended, but now the radio amateurs have taken over. There is a lot of HELL traffic on short wave amateur bands.

WINLINK

Winlink is...

...a worldwide radio email service that uses radio pathways where the internet is not present, and is capable of operating completely without the internet--automatically--using smart-network radio relays. Winlink provides its users email with attachments, position reporting, weather and information bulletins, and is well-known for its role in emergency and disaster relief communications.

Here is my 472 kHz station. At the bottom right are 100WS and Lo6L39,
both of which operate on this band. Here are also two short wave transmitters.
Lo40K39a and 80W.S.a. Receivers that can operate with the transmitters are
Schwabenland and T9k39 Main. The transmitters and receivers are selected with a relay system.



Radio Shack no.4

Here is my HELL schreiber station. The transceiver is a 15W.S.E.b.
This is specifically designed for HELL schreiber.
It's amazing fun to use this old equipment.
