Which is exactly why I did and continue to do what I have been doing. I have been going through this again from mic to antenna and at the same time communicating with the builder for his advice. I have previously fully implemented all of the grounding and bonding advice given to me by members...

Very good advice. I am still waiting for the one I ordered to arrive. I don't think our ongoing blizzard is going to speed things alone. Man it's ugly outside right now in NE Wisconsin.

You sound like my therapist. ;)

I may have spoken too soon with the Lincoln II+. At lunchtime I was using it on SSB with the amp on high and when I un-keyed the mic, it did the same thing as the Anytone was doing i.e. nearly pegged the S-meter and only stopped doing it when I turned the amp off. This radio only puts out about...

When I run the Q5N2 just by itself and listen to the output on my monitor radio, the AM part is still nice and clear but now SSB is fuzzy and crackly. SSB used to be as clear as AM. This problem seems to have started after experiencing the odd behavior of the amp on high with the radio on SSB...

I have a two month old Powermax PM4-120 amp PSU. I have a Carl Built 200HDC amp that can draw up to 46 or so amps. I also have several radios I use with it and each radio draws less than 15 amps. They are never used concurrently. Right now everything is connected to the PM4-120 via a...

So far I think you are 100 percent right to disagree. It definitely did not work well with the amp.

I ordered some Anderson connectors a few days ago and they are supposed to arrive tomorrow. The builder himself said this amp can be used with the Q5N2 and I was even running it at the same lower 30 watt PEP power level as the Lincoln II+. I based this on the dead key and PEP readings from my...

In my Anytone AT-5555N2 I see four IRF520s. One has N16K stamped on it, one has N17K and two have no markings. I have some other new ones from Vishay that are stamped N26K that I bought from Digi-key.com several months ago. Is there a reason Anytone would have three differently-stamped 520s or...

I do still have everything grounded and bonded after the exercise I went through a few months ago. The only thing I did was replace the KL503HD with the new amp. Nothing is soldered or spliced. The amp works fine with the Lincoln at 3 watt dead key and 30 watts PEP. I have not tried it any...

I may have another dodgy connection somewhere. I am occasionally having the amp seemingly lock on after I've un-keyed but only at the high position. It pretty much pegs the S-meter until I shut the amp off. I'll start tracing through this next. It seems like half the patch cables I have...

I did indeed.

Now I am working out the safe power levels I can run this at using my Lincoln II+ V4. It has a max dead key of about 5 watts and max PEP on SSB of 30 watts as measured on my Daiwa CN-901HP. This is the description of the stock amp I bought: 200 2 hg 2 x 2sc2879, Class C bias, low/high power...

Wow. I explicitly stated I am not going to open this up to fuck around with it when discussing extending the power cables. I don't care about the lights or a LED fan. I am a bit on in the years for that. I stated that the fan is loud and it is. Maybe the fan on your Carl Built is a bit less...

The info I posted was what was shown for the default amp configuration. Below are shown the as-ordered specs. The text below "Add To Cart" does not change when you select the optional transistors.

I definitely need to address the fan noise. It's quite loud. Maybe a quieter replacement fan, if there is one that fits, after the 30 day warranty is up is in order. Also going to relocate the amp from the desktop to a shelf under the bench. It's an open shelf in a cool basement so airflow and...

These look like they're just what the doctor ordered. I have several different crimpers but none that look like the one that is used for these. Yet. :)

Well, based on what I hear on my secondary radio the audio is clean. From the directions below I think 7 watt max input carrier means 7 watts dead key max but I'm staying more like at 4 for now. I need to spend some time working out where to set the RF power and mic gain on the Lincoln II+ to...

Splice was the wrong word for me to use. I don't have anything spliced. I should have said extended and any extension would have been 6 gauge using a terminal block. Turns out I don't have to do that either right now at least. I have a 120 amp PSU and 2 gauge wire running from it to a 150 amp...

I had a nice surprise arrive in today's mail. I do need to extend the power and ground wires before I can hook it up to my PSU though. It looks like the existing wire is 8 AWG. I already have a bunch of 6 AWG THHN lying around from other projects so I may just use it. I think it should be...
