If you are used to running SSB voice with little or no ALC indication, well, forget that, and run the 7100’s ALC at about 40-80% indication. Also, Icom has corrected the initial ALC overshoot problem, but adding a capacitor to slow down the ALC is a bad idea, as it may cause ALC overshoot, perhaps arcing your amp or.
Low SWR allows full power for transmit- CAUTION: Protect your transceiver from lightning by ting. The IC-7100 has an SWR meter to continuously using a lightning arrestor. monitor the antenna SWR. Page 32: Connect Controller To Transceiver Drill 5 mm holes for the bracket location. Spring washer Drill 3 mm holes for the tapping screws.
4/17/2016 · SSB Power modification for IC-7100, 10/6/2013 · I’ve had a difficult time getting the Windows audio setting correct for digital modes using a IC-7600, IC-9100, and an IC-7100. This video will show you how …
9/7/2019 · After setting the mic gain with the ALC meter, switch to or look at the COMP meter. The manual states, “While speaking into the microphone at your normal voice level, adjust the Speech Compressor level to where the COMP meter reads within the COMP zone (10 to 20 dB range).” – Icom 7300 Full Manual pg 4-12 or Icom 7610 Basic Manual pg 4-8.
IC-7300 Average SSB power modification – AD5GG, Setting Up Mic Gain and Compression – Ham Radio with K0PIR …
How To Use An ALC Meter — HamRadioAndVision, Icom IC-7100 Modification Low power output on SSB. The issue with the low output of the IC-7100 busied myself now already more than two years long. In the summer of 2014 I am, more or less, encountered by chance on the problem with the transmitter power.
A High ALC Reading is Tempting. G8JNJ found that with modest ALC action the average output power from his FT-897D for a single sideband phone signal was 10 dB below a single tone at maximum peak power. By amplifying the audio input and pushing the ALC reading to the top of the scale, he could increase the average power by 3 dB. …
3/15/2017 · Likewise as in IC-7100 low SSB power ( but not only SSB – i.e FSK441 and JT6M ) it’s the problem of too sharp ALC limiting making the ALC loop acting too fast to let the signal envelope to rise enough. And it’s not the matter of MIC gain setting nor PROC value.
1/31/2009 · What mic are you using, what are the applicable settings on the rig. What is the ALC reading, etc. It’s a little hard to help on something like this without some more info. My first reaction (if you already tried the mic gain setting) is that you have the compression turned up too much. Did you try adjusting the speech compressor?, 11/1/2017 · If you Google the title of this post, I’m sure you’ll come across some results which detail a very simple modification you can make to your IC-7300 which some believe increases the RF output power.This is vague and misleading. The PEP (Peak Envelope Power) of the IC-7300 is rated at 100 watts. This would be denoted by “+Vmax” and “Positive Peak” on the image on the right.
