We’ll need to climb our tower to change the preamps over to be powered through the coax before we can complete the preamp control changeover.Īll in all, we are very happy with the new IC-9700 for Satellite operations. The IC-9700 can power and sequence our external ARR preamplifiers and we plan to use this capability to eliminate the outboard sequencers that we are currently using with our preamps. Setting up PTT and the proper audio levels were straightforward and the combination of MacDoppler controlling the VFO in the radio and the PC doing the APRS packet processing worked well. The direct USB interface was used to a windows laptop for APRS. We’ve also done a bit of APRS operation through the ISS using the IC-9700 and the UISS software. The Spectrum Scope also makes it very easy to locate your signal in the satellite’s downlink and then adjust the uplink/downlink offset for proper tone. As you can see, it is very easy to see where stations are operating in the passband of a linear transponder. The screenshot above shows the IC-9700 display while working contacts using FO-29. The Spectrum Scope and associated waterfall are really nice for operating with linear transponder satellites. The touch screen layout and functions are very similar to the IC-7300 and one does not need to spend much time with the manual to become comfortable using the radio. We’ve made about 50 contacts with the IC-9700 so far. IC-9700 Display and Waterfall – Working FO-29
