There is one for-hire generative AI that advertises "hallucination free". The one thing they're good for so far is spewing nonsense that sounds perfectly okay. When can we get an AI service that scans a text file and determines whether a human wrote it or if it's an AI end product? An AI...

Here's a new one. A base station that looks like the overpriced 40-channel DX2547 radio with the Galaxy name on it. But it's a wolf in sheep's clothing. It contains most of what the larger 'black' radios like the RCI69, Galaxy DX2995 and similar models offer. But in a smaller package. Shoulda...

Flaky power switch with a layer of schmoo on the contact surfaces? 73

Wouldn't hurt to make sure it isn't just the coax jumper cable between the radio and the wattmeter that's gone bad. If you have another radio on hand, set it to the same channel. You can use a small screwdriver shaft into the center pin of the antenna socket as a monitor antenna. If you can...

I did it by putting a current meter in line with the radio's main power. Needs to be the 20 Amp range, pretty much. Setting bias will call for turning the bias trimpot for minimum current with the mike gain at zero keyed in either sideband mode. The trimpot will place zero bias current on that...

And you need an excuse just why? 73

If the radio is aligned wrong, it can make this problem worse. I just wish they had put a tone control on this model. Until someone checks the carrier oscillator to see that the two SSB settings are correct, this is an open question. 73

Well worth every penny you paid, so far. It sounds as if the RFX isn't amplifying the radio's transmit signal, but instead is oscillating. The signal the RFX is creating just sounds like static in the other radio. If you have already installed the RFX with no problem at least five or six...

Opinion? A built-in driver stage is the devil's own invention. Better off with a straight 4. More audio. Wattmeter is not an audio meter. 73

Odds are the amplifier has failed. Clearly you have a post-2007 model with the switchmode power supply. It has overload protection, and it sounds as if it is shutting down for that reason. There is a tiny 2-pin plug just to the front of the radio from the driver transistor. The wires are...

Leave the neutralizing circuit alone until you find that it won't adjust properly. If TC27 sets properly on its own, it wasn't broke and didn't need fixing. Besides, I think that bit of "add a capacitor to TC27" folklore is mostly not relevant. I blame it on what happens with two tubes that...

Condolences to his family. And to the members here. He was a member of this "family" and will be sorely missed. 73

50 years ago the 146.16 up and 146.76 down was the 'alternate' nationwide calling frequency. If a town had two repeaters, this was frequently the 'other' repeater's frequency pair. The 146.34 up and 146.94 down was and probably still is the nationwide repeater calling frequency. The idea was...

A .01uf disc cap across the light socket's wire hookup has been known to knock it way down. YMMV. 73

You gonna build the parts factories? Would be cool. And unlikely. Manufacturing goes where the labor and land and taxes are cheap. The stockholders will send you down the road if you don't cut costs to match your competitors in the same market. You're not just competing for customers...
