It should handle most of the HF modes, but it can be problematic for things like GMSK (for a D-STAR hotspot) and other modulations that don't tolerate signal filtering. (If it uses an FM discriminator

If you are buying something, you might want to look at the DRAWS™ HAT as an alternative. If not, then yes the SignalinkUSB should connect. (Be aware that for some modulation masks, the transformers ca

Current is part of it, and yes a lot of 'software issues' are solved with proper power. The other problem with USB/USB-C connected "wall warts" is variability of delivered voltage as well as current f

The size is the same, but the placement of power, HDMI, Ethernet, and USB ports are different. See documentation at https://www.raspberrypi.org/documentation/hardware/raspberrypi/mechanical/README.md

When evaluating operating temperature on a Raspberry Pi, it is important to remember 'hot to the touch' and 'operationally hot' are two different points. Based on the Pi 3, the point at which it start

Been using RPi 3b with DRAWS™ and it seems to work fine.

Just backorder and get one when they arrive.

Richard, A very valid point. The DRAWS™ HAT integrates a lot of functionality and is purpose built for the applications that use it. Certainly one can build everything it offers, cheaper, given time a

Technical documentation for DRAWS™ -- includes schematic, pinout, etc. https://nw-digital-radio.groups.io/g/udrc/files/DRAWSTech.pdf GPIO 12 and GPIO 23 provide PTT through the left and right DIN-6 co

I use clamp on ferrites on USB and other cables attached to the Pi.

By "at the same time" do you mean simultaneously or do you mean have all of the programs available on the same Pi? To run them all simultaneously on a single transceiver would require managing the dif

A lot of activity around the DRAWS™ HAT. Including a Raspberry Pi image at http://images.nwdigitalradio.com/downloads/ with many applications pre-installed. Support group: https://nw-digital-radio.gro

The Pi onboard audio is only output, no input.

It brings out hardware PTT, Squelch pin, provides power to the Pi from your station 12VDC power, exports some GPIOs, ... Gives you interfacing for two radios and can be configured two run a different

The programs are not specific to DRAWS™ you just need to configure for your hardware. The scripts help with some configuration.

There are a few out there -- here is one focusing on popular digital modes. http://nwdig.net/downloads/ See https://nw-digital-radio.groups.io/g/udrc/wiki/DRAWS%3A-Image-getting-started
