    Well, maybe you have heard of these per chance. Ever heard of clover? Or how about G toR? Did you have some issue with those?

    That's because, with the exception of some experiments with D-STAR on HF in the Phone bands, there isn't any operation of these modes below 2 meters. I've read discussion about trying Fusion on 10 meters, but I'm not aware of any actual use of it there.

    You're getting off track. I was simply trying to ask a clarifying question of @KA4DPO but that question was summarily deflected and remains unanswered.

    it's a free country --- ask whatever you want! But these fellas disappear quick when they have to defend their answers to real questions that they don't really understand, it seems.

    Anyway.... I solved several more major problems today and decoded three more emails from 900 miles away in the heat of the day, so it was a good day. Soon I am going to need an army of volunteers to do an even wider testing of this thing....

    I would think that it takes a very special something, to say right out in public, that a modem DOES NOT READ PACTOR 4....when the gentleman who

    -- designed it
    -- manufactured it
    -- approved the instruction manual for it


    has just told you in plain English, that it DOES.

    Yes, that is quite something unique. I have never seen something like that done before. Never.

    It is like telling John Garand that his rifle will not shoot. Amazing. How people allow that to go on, in this forum, is quite amazing.

    I'm having the same trouble trying to get someone to understand that Winlink servers do in fact have active busy channel detection on them. He's convinced they don't and the evidence is in the fact there are occasions where a Winlink server will accidentally contribute to the QRM of an ongoing QSO.

    Please don't put words in my mouth. I was not asking him to defend anything. I was just trying to understand what they were getting at.

    Sir, I'm not trng to put ANY words in your mouth, sir.
    I may have replied to the wrong person, it appears, but that was an unintentional innocent error if so. I'd appreciate a bit of grace, sir
    please continue forward with whatever you were triying to do and leave me out of it.

    i have my own questions to ask, Sir!!

    There are also people who believe the earth is flat.
    I meet some of these kinds of people in my day job as an anesthesiologist.
    Cheers,

    Here's a couple more email that I read.....from 900 miles away...... today.....

    MID: KATRLV3KNRBU
    Date: 2019/09/10 19:32
    From: SMTP:docvacuumtubes@gmail.com
    To: KX4Z
    Subject: Test 4
    Mbo: SMTP
    Body: 224

    This is a test to see if my idea of having the station check every few minutes for (E-mail) will give me some traffic to test by. The first hour was a complete bust, there just wasn’t any traffic.

    (I deleted the cell phone, obviouslly)

    These are starting to stack up now!!!! The hardest task of today was figuring out a way to force emails through PACTOR with just me, and no helpers at either end. I found a way, and that makes continuing experimentation much easier now. You don't always get the entire message of ccourse. (That's the advatnage of being the person USING ARQ, right?) As we've explained, oh, maybe a hundred times or so and some people still don't get it.....if you lose a packet (that happened due to severe QSB on the 3rd email partway into George Washington's Farewall Address) --- it turns in to mush after that. No one has yet done any research into whether you can recover.....that i know of anyway. Such is life! if you tossed in a TON more forward error correction.....maybe you could get through it but I think I issed two packets on that 3rd email at one point. ... signal just ddisappeared for an instant. A better solution that doesn't waste bandwidth is what i've proposed: diversity receivers, networked. IF enough bright people decide to get off their fanny's, you can have it.
