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 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...

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

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

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...

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

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

Is this normal behavior, even though I have the equipment properly grounded? I checked with a continuity meter, and everything looks good. However, I notice that while checking the SWR and power settings on my Autek WM-1 meter, the SWR decreases when I touch the metal case or the aluminum box...

Why is there no ham radio mod like audio boost or hi-fi I only find warc mods or freq expand

want to do a trade, a Palomar 300a with 8 extra tubes at 85 to 90 percent, plus some cash for an Icom IC-7300 I use it on 20 meters a few times with no issue

This right here is either on meds or has lost touch with reality $900.00 I can't even sell mine for $325 with spare tubes...

Looking for advice on an audio recorder or DVR to use with my Icom 746 non-pro I was used to the DVS-2 when I had my Yaesu FT-890, nothing expensive as it's for experimental at the moment, which there was a way to rewire it to use with any radio

You know how on the FT-101e when you want to tune the radio or an amp, you would switch to CW for a steady carrier I'm having brain fart on my new to me icom 746 non-pro when I put tit on CW no carrier is produce I would have to use audio or whistle on ssb There's got to be another way

Has anyone here owned or currently own an Ameritron AL-811H? If so, have you performed the internal fan and bias correction as suggested by W8JI? Which bias setting did you use: low, medium, or high? Additionally, did you set the fan speed to low or high? I primarily engage in rag-chew on SSB.

Does anyone here know how to decipher the serial number from Ameritron AL-811H to see when it was built serial number=AL-811H-24294

i have an Autek research WM-1 meter. I'm trying to do the quick alignment as described in the manual I included an image Am I reading it right using a 50-ohm dummy load, set the SWR to 1.1 ??? Also, I've noticed that when on the 2000 scale, the SWR doesn't register only on 20 and 200, and when...
