On part one you said you'd be using just two wires on the accessory plug, which l thought was strange, but on part two it looks like you used 4 or 5. Can you please provide info on this as l'm looking to hook a microphone preamp to the 7300 through the accessory plug. I know my reason is different than yours but I'd like to learn more about this plug. Thanks.
Great video, I am using pin 12 for AF output and pin 2 for GND on the ACC port adaptor, as you outlined, to connect to a mixing console to capture the audio from the radio for recording. This option works great except for when I am transmitting and I am hearing my muffled audio on the AF output of the radio. It sounds like the monitor is turned on and over driving, but it is turned off and the output is set to 0. I have verified that it is not RF interference finding its way in to the mixing console or from one of the the MICs or cables connected to the mixing console. Any thoughts on removing the unwanted audio from the AF output of the radio?
Hi. I haven't had a problem with muffled or distorted transmit audio showing up on that pin. It sure sounds like RF getting into something. Have you tried putting torroid chokes on all of your audio cables just to see? Another experiment would be to turn your transmit power all the way down to 0 and see if the audio goes away when you transmit. Even at 0, the radio puts out a little power - maybe 1 watt or so. If that makes any difference, the the problem is likely RF getting into something somewhere.
@@HamRadioA2Z thank you for the reply. I tried the torroids and that did not solve the problem. I did however do that unspeakable thing that we as Hams refuse to admit, I looked at the manual. Looking at the pinout diagram for the ACC port on page 2-5, it shows an isolation transformer and a variable attenuation circuit in line with the audio output and the MIC input. So reaching back to my days as a live sound engineer, I put a DI or Direct In box inline between the radio and my mixing console and the issue went away.
Why using the ACC instead of any other way? Not against it, just asking, as I am receiving an IC-7300 today, and have my mixer and powered speakers already set. Need to input radio then to mixer once it arrives.
Hi. There are 4 places that you can get analog audio out of the radio: 1) The headphone jack on the front 2) Pin 8 of the microphone jack on the front. 3) The external speaker jack on the back. 4)The ACCessory jack on the back. You could use any one of these to run audio into your mixer with an appropriate resistor divider. The reason I chose the ACC jack is because it is the only one with a fixed output level. It does not change as you adjust the AF gain knob. So, when I set a level on the mixer it stays, regardless of what I do with the volume control on the radio. If you want your mixer/powered speaker volume to change with the knob on the radio then you will want to pick one of the other outputs. Enjoy the new rig! 73, Tom WA2IVD
Hi Antonia. I go through which pins to use in video #8, right before this one. Here is a link: ua-cam.com/video/IGhkoTVhhHc/v-deo.html. The part about the connector pins is about 5 minutes in.
Hello, Can I input audio from my audio rack/chain directly into the audio pin on the ACC port in the back? And will I benifit with any TX audio quality?
The short answer is that it depends on the audio coming out of your audio chain. If you have a really good mixer and microphone, then it will almost certainly be better than the stock hand mic. You may need to adjust EQ settings either on your mixer or in the radio menus to tailor your audio to typical ham radio bandwidths. The MOD input on the Accessory connector is looking for standard line-level input audio.
@@HamRadioA2Z I was told that it would increase the "available" bandwidth of audio coming in rather that just using the front end (mic plug), but also I don't want to go actually wider to cause splatter..but I'll be experimenting with it in the next few days to check it out. And thanks for the reply!
Because the 7300 is a SDR, it does a pretty good job of hard limiting the bandwidth to FCC standards. That doesn’t mean that you can’t send distorted or bad audio, but at least it shouldn’t extend outside of your 2.5-3khz bandwidth window. Good luck with your experiments. I’ll be interested to hear how it works out.
I don’t believe so. The receive S-meter basically works by showing you the inverse of what the AGC is doing. The stronger the signal, the more the AGC turns the gain down. So the meter is driven from the AGC signal. If AGC is off, there is nothing to drive the meter.
AGC - Automatic Gain Control automatically reduces the gain of the receiver when very strong signals are present. It helps keep close or really strong signals from becoming too loud or distorted. One thing that Mohammad pointed out in a comment below is that I didn't remind everyone to set your AGC to FAST when working digital modes. If your working SSB, having AGC set to Slow can reduce background noise and make listening more comfortable when your working someone with a strong signal. For digital modes, you want your software to get as much signal back as quickly as possible when a strong signal near the frequency of your intended station goes away. You can always turn your headset or speaker volume down or off when working digital.
Good series. A great screen poker for the IC7300 is the eraser on the end of a lead pencil.
Good tip. Thanks!
No worries Tom. Still working my way through the series. 73s VK3JFP

Another very helpful video. KF0CTL.
The audio level is very low on this video! With my audio all the way up I had trouble hearing this.

Great videos. Thoughts on the ICOM IC-7610?
Thanks Jim. It looks like a great radio. A friend of mine has one. Will probably be a while before I’ll be able to do a series on that one.
