Minima Transceiver

Looks like a new QRP transceiver design came from Ashhar Farhan, the creator of BitX. It is a general coverage HF rig, with Si570 oscillator controlled by Arduino and both CW and SSB mode working, that can cost up to 100$ all new parts.

An interesting design approach at this transceiver is the high IF of 20 Mhz, the VFO mixer and the front-end filter, that uses two low pass filters, for operating between 0-15 MHz, respectively 15-30Mhz.

All the information regarding the design and how it works can be found on Farhan’s Minima Transceiver page.

And the discussion group at www.freelists.org/archive/minima/recent

Made me curious to build it, so I am already working on a PCB design

Remote990 Internet Access to the TS-990S

Remote990 is a Windows program that lets you send CAT commands across the internet to a remote TS-990S transceiver.

When communicating with the TS-990S via the internet, the radio requires CAT commands to use UTF-16 character encoding. Most well-known application programs, however, use ASCII encoding, so it becomes necessary to convert between ASCII and UTF-16 if you want the application to communicate with the TS-990S.

Remote990 is a simple utility that performs the required conversion between ASCII and UTF-16, and in effect connects the application to the radio. No change to the application program is required – you run it exactly as you would on a PC connected directly to the radio.

TS-590 CATfix

TS-590 CATfix

A Windows utility that controls IF Filter switching and configures the radio for digital working

CATfix monitors the radio’s TF-SET button, and (optionally) toggles between IF Filter A and IF Filter B when you press and release the button. This is especially useful when chasing a rare DX station that is working split – you can set up a narrow filter to listen on the DX station’s TX frequency and a wider filter to monitor around your own TX frequency, then automatically toggle between the two filters as you press and release TF-SET.
