SDT21 simple digital transceiver

Product no.: SDT21

simple "digital" monoband transceiver SDT21

 

The goal of this project was the development of a simple to build CW monoband transceiver based on the direct superheterodyne principle with crystal control a la "PIXIE" or "Rockmite", but with much better technical data. To minimize the circuit effort, the concept should be as highly integrated as possible and realizable without hand-wound coils. Furthermore, for the SMD phobics, SMD placement was completely omitted this time. Despite these specifications, it was possible to fit the entire circuit on a double-sided PCB with dimensions of 69x52mm, which allowed it to be installed in the small TEKO A2 package.

The main focus of the circuit is based on the little known fact that digital inverters or gate devices of the 4000 CMOS series can be operated as analog amplifiers by a circuit trick, important here is the use of the unbuffered IC variant (index UB).

Schurr-Profi M

Stainless steel polished V2A Niro

Dimensions 100x80x28mm

Special edition stainless steel

 

The paddles are mounted backlash-free with hardened cylindrical pins in brass plain bearings. Due to this connection the bearing is absolutely maintenance-free! The advantage of this paddle bearing is that, unlike a ball bearing, no gumming up can occur over the years and the bearing can fail or become stiff. Any adjustment of this paddle bearing is not necessary.

Hard silver contacts as well as fine thread are standard.

SOTA Schurr Wabbler by Stefan Bergsiek

small portable key from Schurr / Bergsiek

gold plated

about 170g

No springs are installed. The paddle reset is made by magnets

The paddles are mounted without play with hardened cylinder pins in brass sliding bearings. Due to this connection, the bearings are absolutely maintenance-free! The advantage of this paddle bearing is that, unlike a ball bearing, no hardening over the years can occur and thus the storage can fail or become difficult. Any adjustment of this paddle bearing is not necessary.

Hard silver contacts as well as fine threads are normal standard.

The key is delivered with a 1.5 m long high-quality cable and 3.5 mm jack plug-in connector.

The key is made of full brass

Can also be installed as a replacement mechanism in an old ETM
