CAT & Audio interface for FT-897

In box CAT

On the internet you will find a lot of schemas for CAT & Audio interfaces. In this post you can see the result of the interface on a standard euro PCB board. With the ‘diylc’ software I had made a PCB design to reproduce the schema. The nice alu-case (part number: ADG-D105.30.160) and the audio …

Build SDR radio with DR2B from YU1LM

CIMG4159

In this post I will show the steps I had made to build the DR2B SDR receiver hardware from the OM YU1LM. The main reason to build / use this small part of hardware is to use it as an IF monitor for my FT-736 and FT-897d Transceiver(s). The fixed MF input from the FT …

You can move the antenna rotor by hand via the ‘joystick’ and via the software on the PC. In the download section you will find (asap) the complete building manual. Credits …

Receive CQ from ISS Space Centre

Today I received the ISS ‘loud and clear’ – 59+ on the 145.800 Mhz. I have tried to make contact back, but the TX was active on the wrong frequency, it should be 145.200 Mhz. If you want to listen to it, click on the sound-link. Recorded CQ from ISS dd:311013 (wav-file)

RTL-SDR dongle and Raspberry Pi 512 Mb

SDR software, main screen

Today finished the soft- and hardware solution with the RTL-SDR and RPi. The main idea is to use the low-cost ($25) RTL-SDR dongle on the RPi and connect the RPi with a portable computer, with the SDR-client software on it. The test antenna is the 3-element HB9CV antenna only for 144-146 Mhz. This means that …
