DigiTwist.

Postby G4EWJ » Thu Sep 14, 2017 11:51 am

DigiTwist is an experimental 2 axis satellite tracker, primarily for the HamTV transmitter on the ISS. 2 broadcast satellite dish positioners are connected together and are controlled by a dual Diseqc pcb.

I've started to put details on the BATC Wiki: https://wiki.batc.tv/DigiTwist
Circuit diagrams and software will appear shortly.

The most difficult part is the drilling of the complex shape of the positioner rotor arm in the joiner bar. Quotations are currently being sought for production of a batch. To gauge demand, it would be helpful to register an interest by PMing or emailing me. my callsign at yahoo dot com

I have the parts list ready for the test pcb. I didn't make a note of who had a pcb or joiner bar at CAT17, so please could you email me and remind me.

For Anyone interested in building this project, I found a single TM-2600 at £41.25.
This is from
https://www.world-of-satellite.co.uk/Te ... tal-Geared

There may well be other cheaper options but this is the best deal I have managed to find.

I have nothing to do with this company, but will be placing an order soon.
