    Bullets can move in and out of the case from recoil if they're not crimped good. It would be worth while to describe what's going on in painful detail. Failure to feed, fail to extract, etc. Always, intermittently, first round, last round, everything... The type of bullet etc.

    Antenna location causing high SWR

    Is the antenna connected to the radio when you're using an ohm meter?

    1. Never use a dremel. Use black emory cloth, oil, and your finger. 2. If it only jams on reloads, maybe it's the reloads.

    Antenna location causing high SWR

    Can you mount to the top of the faring strut? Maybe just temporary to see?

    President Lincoln II+ V3 AM Choppy Squelch Issue

    If one could mod the radio with a standard squelch circuit, it would maybe fix the volume issue too. The Lincoln squelch uses an analog to digital conversion of the output of the 2nd IF signal to compare with software and send a low kill signal to the audio op amp negative input. I simple...

    President Lincoln II+ V3 AM Choppy Squelch Issue

    They can avoid this kind of attention by fixing my radio. Just put an old fashioned squelch that works on it.

    President Lincoln II+ V3 AM Choppy Squelch Issue

    Sent it again to President. Made a youtube video to show them how AM is choppy in AM mode on signals that sound fine and very strong on the meter if squelch=1. And also shows how audio is completely cut on squelch=0 on a quiet channel. They wrote me and said it meets factory specs on the...

    President Lincoln II+ V3 AM Choppy Squelch Issue

    Looking at the schematic, there's several parts near the output amp, a transistor, caps, resistors, labeled NC. Pin 2 on the amp goes high or low to kill audio output. I wonder if those omitted parts are supposed to smooth that function and got left out for some other reason. Audio needing to...

    President Lincoln II+ V3 AM Choppy Squelch Issue

    Shipped it Florida for warranty service last week. I took a youtube video of exactly what it's doing and sent them the link so there's no confusion this time.

    President Lincoln II+ V3 AM Choppy Squelch Issue

    Does anybody notice if squelch works "better" if the volume is turned up real high? Just wondering if the low volume and touchy squelch are related since the audio amp gets a kill signal on it's "neg" terminal to initiate audio squelch.

    CB FM

    I suspect the reality of the change will actually be quite boring and uninteresting. Even social media's typical push to make something out of nothing has little to say. Maybe one channel, one of the old unused remote control channels, could be used for guys who want to broadcast position info...

    CB FM

    Will this be followed by proprietary digital modes that sound like a GE Mini Gun to everybody else?

    FS: Lincoln II+

    Does it have the issue where AM is squelched and choppy if you run the squelch? I'm still working through issues with mine with the manufacturer.

    President Lincoln II+ V3 AM Choppy Squelch Issue

    Could the AM/FM squelch circuit be injected with demodulated audio, or carrier, and not actually noise as has been done since the beginning.

    Removing ethanol from gas

    Heard about a P51 Mustang pilot who couldn't get high octane gas, so he would leave the gas in glass jars in the sun and then siphon the higher grade stuff off the top of bottom or something like that.

    TinySA pocket-sized Spectrum Analyzer

    I use the nova nva all the time to test antennas. I'm going to try using it as a signal source tonight by using the same frequency for the start and stop of the sweep. Looks like it may put out more power than the tinysa but for sure don't know this. (It get more complicated trying to...

    President Lincoln II+ V3 AM Choppy Squelch Issue

    I sent mine to President after calling them. Still not a proper AM squelch. Set to lowest setting "1", and all audio is squelched. Have tried various engineering menu S9FAO settings, and returning them to factory when it was all said and done, having seen no difference at all. Maybe a part...

    President Lincoln II+ V3 AM Choppy Squelch Issue

    Any luck finding any more info one what those AM/FM squelch settings should be. Could be unique to each radio I guess. I'm baffled by what S0FA1² means. Looks like several ASC tweeks there too. Who really makes these radios? The company itself is now strictly import/export from what I can...
