It has been a few weeks since my last update about the IC-706 remote rig project so here is a new one.

DIY remote kit for the IC-706 part 5: Power on / off sequences
In my previous post I described how I solved the power connections for the radio and the front panel when they are physically separated from each other. In this post I will explain the software part of the power on / off procedure.
DIY remote kit for the IC-706 part 3: Keep-alive emulation
Yesterday I have implemented emulation of keep-alive messages on server side. This means that the keep-alive messages sent by the front panel roughly every 100 ms are no longer sent over the network; instead, they are generated in the servers main loop with 150 ms interval.
My mcHF UI board is alive!
After completing the UI board I really wanted to see it work and test it one way or other without the RF board.
My HF2V during winter 2010/2011
I took a few photos of my Butternut HF2V vertical antenna during my winter holidays 2010/2011. You can click on the images to get higher resolution photos. Enjoy!
PBT Mod for the IC-765
As you may already know, the IC-765 has IF-shift but no passband tuning. There is, however, a simple mod originally designed by Gerd Henjes, W2ISB, which allows the IF-shift button to tune the passband while the IF-shit button is in OFF position. This mod is described in the VE3HUR IC-765 notes and reproduced here with some illustrative pictures, as well as a video demonstrating the difference between PBT and IF-shift
IC-765 Overview
The IC-765 has been ICOM’s flagship HF-radio for many years. Even today (2006) it represents excellent value for money as it has one of the best receivers ever made. The IC-765 has 4 IF stages (69MHz, 9MHz, 455kHz, 9MHz), built-in power supply (PS-35) and automatic antenna tuner (AT-150), and it comes with 500Hz CW filters (mounted from the factory. Optional 250Hz CW filters (FL101 and FL53A) are available, too, as is the optional FL102 6kHz AM filter.
