Dual vfo SSB transceiver project

Image
This is a project that looks very interesting, it's a dual vfo SSB transceiver published by Pete Juliano, radio ham N6QW and co-host of the popular podcast Solder smoke. so let's get started the first job is to read all the documentation and then read it again. After reading the documentation and printing the documents I emailed Pete and asked if I could get a copy of the Arduino sketch for this project, Pete sent me the sketch as requested. Fantastic thanks, Pete. OK, next job is to get all the parts together,  all parts are all available and as a bonus, we managed to get the mixers ADE-1 supplied by mini circuits in NewYork and mini circuits supplied them free of charge as a sample. sofar so good, ok so let's get a bill of materials together. To do this we used my favourite cad and PCB design tools, Using Easy EDA we started to sketch up the schematics and create a list of part, why redraw the schematics? we hear you ask, we did this so at a later date if everything works

ARISS SSTV Event Scheduled for April 11 - 13

Image
 ARISS SSTV Event Set for April 11-13, 2022 From the International Space Station, an ARISS Slow Scan TV (SSTV) event is planned (ISS). The event is scheduled to begin on April 11 at 16:30 UTC for setup and operation and will finish on April 13 at 12:00 UTC. These are approximate timings that may fluctuate based on crew availability. Images will be downlinked at 145.8 MHz +/- 3 KHz for Doppler shift, and the planned SSTV mode of operation is PD 120. This event will commemorate Cosmonautics Day and Women in Space. Radio enthusiasts participating in the event can publish and see images in the ARISS SSTV Gallery at https://www.spaceflightsoftware.com/ARISS SSTV/.

  RSØISS - SSTV activity Thursday April 7 start about 08:00 GMT, stop about 15:35 GMT* Friday April 8 start about 08:40 GMT, stop about 16:10 GMT* Description: Russian cosmonauts on the International Space Station (ISS) are planning to transmit Slow Scan TV images on 145.800 MHz FM using the SSTV mode PD-120. The transmissions are part of the Moscow Aviation Institute SSTV experiment (MAI-75) and will be made from the amateur radio station RS0ISS in the Russian ISS Service module (Zvezda) using a Kenwood TM-D710 transceiver.  Thursday April 7 start about 08:00 GMT, stop about 15:35 GMT* Friday April 8 start about 08:40 GMT, stop about 16:10 GMT* *Dates and times subject to change.
