Loud steady clicking on TX

[2NC995]

A local dump truck driver seems to be having quite the issues. He drives through town 20 times a day, running his 100 watt mouth the whole way.

The problem: on TX he has a steady, rapid ticking/clicking noise. Very loud and bleeds across all channels, and I suspect, beyond.

Even when he’s talking on 19 and showing an s4 or so on my radio, the ticking completely wipes out my receive on 38lsb.

What in the world am I hearing??

His buddies apparently don’t hear it, and think he sounds great...haha.

Possibly the modulation limiter clipped, or the amp being overdriven or both. We have a local that runs his 6 pill like that. Even on 38lsb too.

 

[2NC995]

I’ve heard some bad sounding radios, but this is a first for me.

Totally obnoxious.

If he was on SSB I would say his amplifier has no SSB delay so the relay just clicks constantly. If he's an AM'er hard to say, probably has something way overtuned and outta whack.

 

[2NC995]

What gets me is the perfect steady rhythm. You can even here it in a dead carrier.

Never seems to vary at all.

 

[Shadetree Mechanic]

Maybe his amp is oscillating?

Is he collector modulating the finals with fuel injector noise? Have him rev the engine while keyed up and see if it changes.

 

[2NC995]

Maybe. I’ve heard a lot of crap over the years, but this one is something else.

Always amazes me how and people can screw up a radio. I remember years ago there was a local fellow that ran a galaxy of some sort with every imaginable “tune” done to it, into a fairly large tube amp, a maxed out d104, and an Antron. I would hate to have been a neighbor, because he plastered every channel in town all night long, and I bet you couldn’t pick up a corded telephone without hearing him. I never heard a radio that sounded more like he was at the bottom of a well screaming into a tin can. And yet, no one wanted to tel him he sounded like garbage. Lol.

It really sucked, because I always liked working DX late in the evening looking for those weak signals, and he too wiped out the whole 40.

Hadn’t personally talked to the guy 543. I may, if I can get an idea what to look for.

I think that guy lives near me.

The magic combination it a super tweaked and tuned radio driving some type of small shit box amp you call a modulator, driving a sweep tube amp that already has a built in driver.

The final tubes in the amp should be making at least 250 watts each. If they aren't you need to buy more swing, bigger mosfets or something.

 

[2NC995]

I’m not happy unless my box has 16 pills the size of alka-seltzers and everything running 20 volts, including the D104.

You also must remove any low pass circuit. Since that will only lower your total output.

 

[2NC995]

A couple trends I saw here some 20 years back...always brought me chuckles:

1. Removing the headliner and making a copper wire “spiderweb” inside the roof a car.

2. Running ground wires off all the equipment in the car and into a five gallon bucket of rock salt with a section of copper pipe in it.

This probably isn't "it", but, back in the 90's my buddy had an issue with his 2950 whenever I was fairly close by and forgot to turn off my amp. He complained about a ticking noise in his receiver that went away when I turned the amp off.

With enough power you can key an amp relay 1000' away.
