Easy low-power tuning for ICOM radios

**See review QST February 2018 p57**

Click here for instructions.

If you use an ICOM HF radio with an antenna tuner or amplifier you will have noticed the lack of any straightforward way to send low power carrier for tuning. To do so requires you to change the mode to AM or FM, reduce the power and press the PTT. It's annoying in the shack and can be very frustrating in the field. This is all the more of a problem if you use a narrow-band antenna such as a magnetic loop that needs frequent re-tuning. It's also a problem if you use your radio with an amplifier

Various "solutions" have been suggested, the most common being a dongle with a capacitor and a resistor. While this works, the tune period is fixed and it will not tune reliably twice in short succession. The fixed tune period is particularly problematic if you use your radio with a high power amplifier as if you see a mismatch you will want to act quickly.

Our Click2Tune for ICOM system provided you with complete and reliable control. It transmits a low power carrier (user selectable level on some radios) without any need to change the mode and for as long as you press the button - YOU are in control. We worked hard on getting the ergonomics right so that it sits nicely in your hand and we even trialed three types of buttons before we found one that had the right size and "feel".We also made it look good to fit in with your shack. It's a great accessory for any ICOM radio that supports their auto-tuner. Tested on: IC-7300, IC-7600 (ant. 1), IC-7600, IC-7610, IC-7100, IC-730, IC-746 (ant. 1), IC-9100 (ant. 1), IC-706 (all variants), IC-703, IC-746. See below for further information on compatibility.

The Click2Tune for ICOM is available as a kit or ready built! We have also written great instructions (build time around 30 minutes).

Kit or built, you get:

  • Branded Molex components
  • Mil spec 4 core screen can for good RFI performance (1 metre)
  • Top quality professional switch and components
  • Double-sided professional PCB and other parts (total 17 parts).

Plug in the Click2Tune BEFORE turning on your radio so that the radio recognises it properly

Will it work with my ICOM radio?

If your ICOM radio has a socket like this on the back, the Click2Tune will almost certainly work with it. Different radios will have the socket in different positions on the back panel.


This product is not suitable for the IC-7700 (and probably other 200 Watt ICOM radios).

The "Tune" indicator on my IC-7610/IC-7600 stays illuminated

The Click2Tune simulates a successful tuning sequence for an external AH4 tuner. There is also a switching sequence that is used by an external automatic tuner to indicate it failed to find a match. The Click2Tune  appears to the transceiver to be a successful tune so sets the display as such. The 'TUNE' indicator simply indicates the transceiver's circuitry detected a successful external AH4 tune sequence. It does NOT indicate the internal tuner is in line.

    Another good after market idea from the team.

    Posted by Steve Down G3USE on 16th Feb 2018

    As good as these modern rigs are, there is always something that the manufacturer misses or does not expect to be needed. In fact as a mainly cw op I don't have a problem producing a tune up carrier for my remote SGC-230. However getting the power down so it does not receive a beating whilst tuning between band changes, involves a fiddle with the "multi" control. This simple product makes it quick and easy.

    Great Product

    Click2Tune worked as advertised with both IC-746 and IC-746PRO.
    I added a small toggle switch in the power feed for both of my units, allowing internal tuner operation. The switch is zip tied to the lower cable strain relief holes, and extends below heat shrink for operation.

    Simple, and it just works

    Posted by Dave Bennett N6OOR on 3rd Feb 2018

    This is a great little tool that saves me lots of times when I change bands. I have a remote antenna tuner and without this button it was hit or miss to get it to engage when I wanted to re-tune on a new band. Now, I just punch the button and watch the SWR drop until the tuner gets it right.

    Click2Tune with IC-7100 & IC-725

    Posted by Ivan on 10th Jan 2018

    Plug&Play - Worked on first attempt with both radios.
    I would have enjoyed it more if I could also use the radios' tune button instead of the Click2Tune button though aware that the radio would stop tuning after 12 seconds when using the radio's tune button.

    Provides what Icom forgot

    Posted by W8TK on 28th Dec 2017

    Easily assembled kit provides 10 watts RF output with the push of a button. Every other manufacturer provides a panel button do to the same thing and now Sotabeams has provided one for Icom users. And it costs only a few bucks!
