Counting down till IC-9700

In a few weeks from now, the new Icom IC-9700 will arrive. The local HAMShop gave an estimate of beginning 2019. The Japanese manual is ready, but I’m still waiting for a translated English version. I had some questions about the new rig, but most of theme are answered.

  • It does have +12 Volt bias to feed external preamps via coax.
  • It is missing PTT out via an RCA connector.
  • It seems it does not wide-band receive.

Let’s wait for another few weeks till the transceiver, announced September 2017, will arrive to it’s first customers.

    Hello my friend! I just got my IC9700. I want it use for EME work with wsjt. I experienced with sorry it has not PTT out signal pin to control another devices in separate RX/TX line. It is very need for me. I want use TX Inhibit signal to be sure that every devices are in RX or TX mode. But if I use the SEND pin to inhibit then I cant it use for as PTT out.

    As I now you are expert in this things so I hope You have any idea or solution for my problems. Is it true …possible?.
    Please let me know if possible any good solution.

    Thanks in advance

    1. You need pin 3 (send) en 2 (gnd) on the ACC1 connector. They will go low on transmit. If you use a tube-amp, put a relay in series between those lines. You can also order a cable:

      Keep in mind, there are some menu settings involved to enable SEND. This can be set per band, eg. 144, 432 and/or 1296 MHz. Unfortunately there is no PTT out via RCA connector, nor PTT-out per band. Some Arduino magic comes in place here in combination with the CAT interface.

      See basic manual, chapter 13 (page 90) for more information.

    Like this person, for EME I want to have my software trigger a sequencer to switch the dish feed Tx/Rx relays from Rx to Tx BEFORE the radio and an external linear amplifier starts transmission… something I could do with TS-2000 but this radio uses the same pin(3) to be triggered itself AND to send out PTT signal to external equipment… very frustrating design when I want the radio involved in a sequence of events.
