Icom Hand Mic Caution Icom Transceivers

K0PIR

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

    Hi Rich,

    I received your newsletter about the Mic mishap (June 15, 2018) and saw below it an add for the Neewer NW-800 Professional Studio Broadcasting & Recording Microphone Set.

    I was hoping you could tell me where to find the cable to connect the IC7300 to the Neewer Mic.

      Hi Eric,

      Nice to hear from you and thanks for the question.

      On those types of mics I used a “Y” cable and a foot switch. The mic comes with a cable, so all you need is the foot switch and “Y” cable. Lots of Hams are using the mics with radios and have good success with them

      Have a look at this: Christmas Savings Plan

      The seller of the “Y” cable is K6VHF on e-bay. A link is in the article.

    Yes – starts up great from terminal and here’s what the terminal displays – don’t see anything in here that would indicate there’s a connection problem from the CQRLOG side. I had the Prolific connection made and the rig running when I captured this.

      It doesn’t look like it is trying to start rig control. Is rig control setup in CQRLOG? I think rigctld should be trying to start.

      I am not proficient with Linux and when I needed help in the past with CQRLOG I used their forum.

      Are you sure you are using the correct serial port under CAT control in CQRLOG?

    Rich – Sometime recently my 7300 suddenly lost all the programming changes I had made from the defaults – I had modified the scope/waterfall appearance, etc. to look like yours – I had been using the hand mic one day quite a bit to set ALC levels , TXT bass & treble, etc. because i find that it’s not good to use my Inrad desk mic when doing that . Then I was away from the rig for a couple weeks due to other commitments. When I returned to it I found that my CQRLOG would no longer communicate with the 7300. I had changed nothing on the rig. I suspected i had done something not good on the computer or with CQRLOG – but after struggling for a week or more to get it going I began to suspect that the rig has stopped communicating thru its REMOTE port, which i use to attach thru a RS232 CI-V CT17 type cable. I had always successfully used a Prolific one, but suspected the cable and ordered a new FTDI one. Did not help at all. So right now I’m really suspecting its the rig.

    You mention above that it might be possible to damage the rig inadvertently while using the hand mic, and I wonder if I have somehow damaged the REMOTE port while doing that.

    BTW, have you had any other reports of the REMOTE port not working?

      Hi Wes,

      No I would not think so. I was referring to transmitting on a non resonant antenna. Say we inadvertantly switched from 80 meters to 20 meters and continued talking without noticing the band change because of the up/down button press. We could damage the finals or worse, if we are using an amplifier, we could do a lot worse.

      Can you start CQRLOG from the terminal window just by typing in cqrlog? Doing so will show what errors are occurring.

      Since you are using the remote (CI-V) and I think that is the easiest one to resolve, does the port show up in Linux? Do the baud rates match in the radio and CQRLOG?

      I don’t have a linux box right now, but that’s how I found my problem on my RaspberrPi and CQRLOG.

    Hi Rich, since my radio is still new,(1 month old) I probably don’t have to worry about it, but when the radios get older and if your still using the hand mike, its a possibility that the wires at the plug or at the mike head may get frayed and possibly short out, and with the up down buttons, and change frequency anyway, which could force you to get a desk mike anyway….which may sound better on the air waves anyway…. just a thought…. cheers…. 73 de Mark W6MRK….

      Hi Mark,

      Nice to hear from you and thank you for the comment. Good thought and I used my 7300 at home a lot and with a boom mic. I didn’t start using the hand mic until it went to my camper.

      The hand mic does get used by Hams at home though because it sounds so good!

      Thanks for stopping by and leaving a comment.

      Best 73,

    I first used my IC-7300 for School Club Roundup in February, and the students would push the buttons, changing the frequency, while transmitting. I cautioned them not to put their little fingers near those buttons, but it still happened a couple of times. Thanks for the warning.
