I have seen that my ICOM radios are picky about the power supplied to them. In my mobile, running an IC-7000, when the voltage got low, it would suddenly power-cycle. I thought that RF was getting into the rig, but later realized that the input voltage was the more likely problem. I am now using... Continue Reading →
IC-7600 RTTY Settings for MMTTY
I have posted these before, but people keep asking about the settings to use for RTTY on the IC-7600 with MMTTY. So this post provides my latest settings. This article provides my latest MMTTY settings screenshots. I am using it with N1MM+ Contest Logger. If you are having trouble using MMTTY with another program (N1MM+... Continue Reading →
ICOM IC-7600 (or 7610) Wiring for use with Elecraft KPA/KAT-500 Power Combo
Note - While this Post documents my IC-7600 setup, I believe this will work equally well with the IC-7610 but I do not have one to test. If anyone can provide confirmation or feedback, it would be appreciated. I have had the IC-7600 for about 4 years and have now added the Elecraft KAT-500 Antenna... Continue Reading →
Your Elecraft KAT-500 Tuner Protects your KPA-500 Amp – until it doesn’t – UPDATED 10/30/2019 and 10/19/2020
I have been using an Elecraft KPA-500 linear amplifier and a KAT-500 Antenna tuner with my Icom radios (mostly the IC-7600 and briefly with the IC-7300) After much research and discussion, I figured out what I thought was the best way to interconnect the IC-7600 with the KAT/KPA-500 so that the Amp would be protected...

Using the KAT-500 and KPA-500 with Icom Radios: Part II – Updated 2 AUGUST 2020
I have continued to investigate the various ways to connect my Icom IC-7300 or IC-7600 to the Elecraft KAT/KPA-500 Tuner and Amplifier. I have received some very helpful communication from a number of other Hams using Icom Radios with the Elecraft KPA-500 Amplifier and KAT-500 Tuner. It appears that there are several different ways to... Continue Reading →
Using the Elecraft KPA-500 and KAT-500 with Icom Rigs: Part I
I now have the Elecraft KAT-500 Antenna Tuner and the KPA-500 Linear Amplifier. My rigs are not Elecraft, but Icom (7600 and 7300) and Yaesu (FTDX-3000). I want to setup the Station to use the Elecraft components with my non-Elecraft transceivers. Since the KAT-500 has connections for the Icom AH-4 antenna control interface, I will...

RTTY on the IC-7600 Using N1MM+ and MMTTY
I have been using the IC-7600 on RTTY with N1MM+ and the MMTTY application for a couple of years now. There are some good directions for this in the N1MM+ documentation, so I am not going to go through all the details. Here is a quick summary, and a screenshot of my setup, including all...

Hints – Using the ICOM IC-7600 on RTTY with N1MM+ and MMTTY
I keep seeing people having trouble with this setup. Every time I go to RTTY Mode, something is not working. It seems that some of the parameters in MMTTY and in the Radio keep resetting themselves. There are some other posts on this blog that may help, but here are a few reminders. Mode -... Continue Reading →
Building an Elecraft KAT-500 Antenna Tuner
I have had a number of automatic Antenna Tuners in recent years.I have had MFJ tuners, LDG tuners and the built-in tuners in my TS-930s, Elecraft K2, ICOM IC-7600, and Yaesu FTDX-3000. They have all worked pretty well. The first LDG tuner, the IT-1100 has been a real survivor. I put it in my mobile... Continue Reading →
Comparing the ICOM IC-7600 and the Yeasu FTDX-3000 – UPDATED 1/21/2018
No more updates to this Post. Interesting developments in the marketplace. The prices on used IC-7600 radios are crashing, apparently as a result of the introduction of the IC-7300 and the IC-7610. I still love both radios, but at these prices, it would be hard to turn down a 7600. Whichever way you go, enjoy... Continue Reading →
