Gone are the days of slowing dialing through the bands to hear what’s there. Of course, I just had to add one, because a panadapter is just too useful to be without. In other words, it needs no interface box - it’s built-in! It also has an intuitive touch-screen and plain-text menus.īut unfortunately it doesn’t have is a real-time spectrum display, or an output for a panadapter. It connects directly to a computer with the supplied USB cable, providing USB audio, CI-V CAT control (virtual RS-232 serial via USB). The 7100 adds DStar digital voice, IF DSP filters (3 per mode, each tunable from 50Hz to 3.6kHz CW/SSB, to 10kHz AM, and to 15kHz FM), a DATA mode that used with SSB provides another set of three filter bandwidths for computer digital modes, and a built-in USB sound-card and serial interface. It’s small, and has a detached control head. Like the old 706MkIIG, it covers all amateur bands (except 220) from 160 meters through 70 centimeters, in all modes. I’ve also added brief sections on SDR hardware and software. If you will use a full-range SDR (or a dongle with a down-converter) you will use the RF tap. If you will use an RTL-SDR dongle (doesn’t receive below 25 MHz), you need the IF tap. I have updated this article to cover both IF and RF taps. In December of 2019 I added an RF output to the 7100 and connected it to an SDRplay RSP1A.

Then after about 30 seconds, the radio will go into TX on its own. The frequency changes as it should in SDRUno and is reflected in the radio if I change VFO on SDRuno. If I make a change in frequency in HRD it changes but SDRUno nor the radio changes. The issue is that HRD loads and sees the VFO frequency, on initial load, however if I change the frequency on either HRD, SDRUno or on the radio itself HRD does nothing.
