In this video, Julian Frost (N3JF) shows how to get the Icom IC-7200 up and running on the digital modes.

The IC-7200, IC-7100, IC-7410, IC-7600 and the IC-9100 only require *one* cable connecting them to the computer, a common “A” to “B”-type USB cable. You no longer need to build a complicated cable or buy an expensive interface box, just a USB cable – one that’s commonly found in most ham shacks. The USB cable carries all the audio data to and from the radio and computer, and simultaneously allows the computer to control the radio via software.

Julian covers downloading the USB Drivers from the Icom web site, and installing them. He shows where to download the free full-featured software, “FLDigi”, covering in detail how to install it and configure it for the IC-7200. Julian demonstrates how to correctly set the radio’s power and ALC levels for transmit, and the Windows sound mixer levels for receive.

Finally, Julian demonstrates the major fatures of the software, including using, modifying and creating macros. The video culminates in a live PSK-31 two-way contact.

While this video concentrates on PSK-31, the IC-7200 is fully capable of all current HF modes when combined with software like FLDigi.

The amateur bands are filling up with very dirty data modes transmissions, we are seeing single PSK and JT65 transmissions taking out the entire modes’ sub-bands in some instances and this is entirely avoidable, not to mention completely unacceptable.

This video is an addendum to my previous video regarding the setting up PowerSDR for data-modes (digi-modes) because there are some settings in Windows which can significantly contribute to IMD on TX.

We take a walk-through of VAC’s (Virtual Audio Cable) Windows driver back-end which defaults settings to 44.1kHz potentially adding unwanted sample rate conversions which can introduce further IMD, then look at how to have Windows reduce audio drive, cleaning up the outgoing AFSK.

The motto of the video is, ensure your ALC compression is zero and that the ALC is in negative figures of between -0.5 to -1.0 dB (legacy radios = NO ALC deflection at all) to guarantee minimum IMD resulting from audio drive levels. Depending on the mode, you may want to drive at even lower levels.

At the January 2014 ARRL Board of Directors meeting, a resolution was passed which asked for member feedback and input pertaining to the increasing popularity of data modes. The information gathered by this investigation is to be used by the HF Band Planning Committee of the Board as a means to suggest ways to use our spectrum efficiently so that these data modes may “compatibly coexist with ea…

In response to requests for clarification from the ARRL, the National Telecommunications and Information Administration (NTIA) has confirmed that it has no objection to the use of a broader range of data emissions by amateurs on the five 5 MHz frequencies on 60 meters. ARRL’s original understanding was that the NTIA preferred that the use of 2K80J2D emission be limited to Pactor III. The NTIA n…
