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

I'm trying to do a mod to my ICOM 746, a small tight spot needs to parallel a 4.7k resistor to R1087. What temp setting would be a starting point to avoid damage

Use of the Heil series of microphones Most of the Heil series of microphones have too little output to sound good on an IC746 (IMHO) without employing a pre-amp. It's possible to turn the mic gain up, use the speech compressor and shout your head off but that's not ideal. You can even buy a...

Thanks, i already tried that when i tried that element on my iCOM SM-20 desk mic, it sounds clean and clear, which leads me to believe i need a pre-amp for this Heil icm mic now to look for a donor that i care steal it from

I need some help or advice. I have a Heil IC-Mic for my non-pro Icom 746, which has low-gain preamps. It only has options for treble (0 or +) and bass (-). My issue is that there’s a slight muffled sound when I speak. I've tried moving farther away from the mic, but that didn't help. If I...

i have the other type pep kit that has 2x and 5x need a 500-watt slug, but I only have a 250-watt slug. 2x mode fixes it

Look here, this is where i buy mine from=https://www.nm3e.com/HElements.htm#H

2500

is this where the +5 -5 % comes in? 50 watts on the 250 slug and 46 on the 100 slug

i heard bad reports about the Daiwa-?? ones not being accurate

Besides the Autek research WM-1 meter, is there another meter that reads SWR without having to recalibrate like the wm-1 ???
