IC-7300 CI-V Voice Keyer [Undocumented] Command

Manufacturers have had built-in Voice Keyers for some time now, Icom have had it in various radio models with varying functionality.  Voice Keyers are useful for many types of operating, contesting being the main one. As mentioned, Icom, have implemented the functionality of their Voice Keyers in various ways, but in all radios a specific

Getting the DX Cluster to Work on KST2Me

KST2Me is an application written by Bo OZ1M, and makes using the ON4KST chat pages much simpler.  It uses the Telnet connection to the ON4KST server so it’s also much quicker on slower connections. One aspect which always bugged me with KST2Me, and sometimes the ON4KST web interface, was that spotting DX to a cluster

Eltek SMPS 1800SI Connection Mod

The Eltek SMPS 1800 SI 48v switch mode power supply is capable of supplying 37.5A (1800w) so is great for powering 48v amplifiers. The only issue, which is common to most rack mounted SMPSs is they have proprietary connectors on the rear meaning a datasheet or manual is required to know which pin does which.

Woodbox Radio TMate 1.0 Windows 10 Driver

I bought the TMate v1.0 “VFO Tuning Knob” a few years back at Friedrichshafen for use with my Flex-1500 as the TMate was much cheaper than Flex’s own “FlexControl”. When I bought it I was probably still using Windows XP, but I certainly used it with Windows 7 without an issue, but on Windows 10

Getting started in Meteor Scatter (MS)

I’d like to share with you all my passion for working stations on VHF (6m, 4m and 2m) using Meteor Scatter (MS) as the propagation mode.  I wrote this during the peak of the Perseid meteor shower in 2015 as it’s much more likely that a newcomer, even with a modest VHF station, inspired by the article

Yaesu FT-817 IF Tap for SDR

As with my other radios (IC-756pro3 IF Tap page, IC-910H IF Tap page & IC-706mk2G IF Tap page) I wanted to tap the IF (Intermediate Frequency 68.33MHz) out of my Yaesu FT-817 to allow monitoring on an SDR radio and associated software,  I mainly use my FT-817 as a piece of test equipment and having

Icom IC-706Mk2G IF Tap

As with my other radios (IC-756pro3, IC-910H & FT-817) I wanted to tap the IF (Intermediate Frequency) out of my Icom IC-706Mk2G to allow monitoring on an SDR radio and associated software. The IC-706Mk2G has two IF frequencies, I tapped the 1st IF at 69.0115MHz (the 2nd IF is around 9.0115MHz) and used a PAT

Mobilinkd Bluetooth TNC Auto Power on Mod

In my car I use an Icom IC-2820 which is a dual band (dual receive) mobile radio, but only ever monitor one side at a time (the other side has the volume down) and in the previous car I used that side for APRS.  Until recently I was not able to find a way to

Icom IC-756pro3 IF Tap

The Icom IC-756pro3 has 2 options for tapping the IF, one is at 64.455MHz and the other is at 13.345MHz taken from the bands scope circuit.  This article covers tapping the IF at 64.455MHz which I found more useful for using with an original FunCube dongle and an RTLSDR dongle, both of which work from
