Icom IC-9100 RTS to CAT control

The IC-9100 that I have has a USB port on the back that allows audio and cat control directly from the radio. It works as advertised, and works generally well.. BUT.. a number of the software programs I like to use (WSPR) don’t have CAT radio TX control, they use the RTS method. I had…

RaspberryPi WSPR Beacon – WsprryPi

The inspiration to purchase a RaspberryPi originally came from reading an article about turning it into a simple HF WSPR beacon. The device will output around 10 milliwatts directly from the GPIO4 pin and once connected to antenna will transmit away!. The first step was to build a simple band pass filter, i choose 30m/10Mhz…

Band Pass Filter Kit

Another Project for the Raspberry Pi when I get a chance is to try WSPR using the box. To make sure this works properly, it is recommended you use a filter of some sort. I ended up with a simple 10MHz (30m) bandpass filter as a kit from kits and parts in the US. it took 2 weeks…

Idiots guide to 144Mhz WSPR

WSJT, MAP65, WSPR, and WSJT-X are open-source programs designed for weak-signal digital communication by amateur radio.  Normal usage requires a standard SSB transceiver and a personal computer with sound-card. WSPR (pronounced “whisper”) stands for “Weak Signal Propagation Reporter.” This program is designed for sending and receiving low-power transmissions to test propagation paths on the MF and HF and VHF/UHF…

WSPR Test 432Mhz

Tonight Leigh vk2krr and vk3smc and myself played WSPR on 432mhz. 330km path. Not bad for a verticle in my backyard. 🙂
