Today, I dropped off my two ICOM radios, the 7300 and the 746, to recalibrate the S meter and to fine-tune the receive and power meters. I asked the technician if he could check the ALC on the 7300. He responded that nobody uses ALC anymore. Did I miss something over the last five years, or is...

Time to experiment again using a Myantenna 40-10 56.1 and a 1.1 current choke. The only bands of interest are 40, 20, and 15 meters. The antenna will be used in an inverted V with the apex 30 ft above ground. I'm trying to find out what size coax jumper to use as the counterpoise between the...

Looking for a recommendation for a high-power attenuator pad of 2.5dB for my Icom 7300 for the ALC overshoot i tried this old skool gadget, but it's no go. The variable is very sensitive . And the overshoot is still there . This is the one i just tried today:

i found another 575-m6 i another box, so 4 Astatic mic 3=575-m6 and 1 amplified tug-8 still for $200.00 plus shipping. I'm done with CB stuff

i have a working Astatic 575-m6 and a 2nd one for parts or to fix it also works, but needs a better housing and the cable. Also, an amplified D104 tug-8 is in good working order. Both are wired for a 4-pin Cobra. asking $200.00 for all, plus the ride from Florida working towards that new ICOM...

I finally received a response from the guy. i ask= Hello, i found your article for the ICOM 7300 to increase the average output i would like to try this mod. But I have a question, will doing this cause splatter when using an amplifier?? His response is From:QSL Manager OT 27 Grzegorz SP3RNZ...

I found a video where, if you go into tech mode by using a shunt in the back of the radio, then press menu & function, then power; if you increase the RF power from 100 to 120, it increases the average power. Instead of seeing 50 watts average, now you will see 60 to 75 on average and 130 on...

It does NOT increase the power output. That stays the same, only the average power is increased. Here is the article =https://sp3rnz.blogspot.com/2017/01/icom-ic-7300-ssb-power-mod.html

Has anyone here performed the capacitor mod using a tantalum capacitor to increase the average power on SSB? The radio typically only operates at 30 to 40 watts. The mod is supposed to increase it. This modification was done by SP3RNZ. I'm trying to hear the pros and cons.

selling my bird 100A element in good working order. Since moving to the ham band, i had to move to the H model instead of the A asking $85.00 free shipping

Selling an ICOM SM-30 desk microphone. It has a 1/8 jack on the side for use with a foot switch or hand PTT. The audio quality is Good; I have upgraded to a Heil-ICM $80.00 plus shipping

Well because i wanted to do this mod 1st in am all i had was a piece of bread with a couple of sips of coffee. After I did the mod shake was getting worse checked my sugar, i was down to 76. Some OJ, a piece of a candy bar, jump-started me to normal again should of known better to have...

The monitor function on the IC-746 tends to have low output compared to receiver AF volume; therefore, in order to listen to yourself, you have to increase the volume. When the PTT is released back to receive mode, the AF setting nearly blows your speaker or your headphones.Add a 4.7K resistor...

Well, i took a chance, heart racing, feeling like them guys in the movies trying to defuse a bomb, red wire, white wire, shaky hands. But I solder that sumamabitch resistor on there, thanks for the replies. Now the 8 o'clock position is like 1 o'clock position. Reason for the mod is when the...

i can verify it does work without the resistor i had to have the volume at 12 to 1 o'clock i held the resistor on the 2 spots while the wife connected the power cord, listening through the headphones, i had to lower the volume to 8 o'clock. Now the bad. i need a better headband magnifier. 3.5 is...

Thanks, loosecannon, i fixed the typo, but yes, 1087, and i uploaded the right pic. The resistor with 223 is the 22k ohm

Look at the schematic, it's a R108722k ohm resistor. To me, it looks like i can put the 4.7k to pin 3 and pin 4 ?? Icom printed boards on the service manual suck, they use a red color for background so you can't see chip lay out
