Episode 102 - Rex harper - W1REX

Rex Harper, W1REX, became an amateur radio operator from his early memories of radio as a kid and his desire to do electronics as a hobby. His love for QRP and later QRP kit building came from wanting to build electronic devices in an evening or two that just worked. Rex shares his ham radio story and the development of his business, QRPme, with Eric, 4Z1UG, in this episode of QSO Today.

Hi Eric,
I am not sure where this idea goes.

It was picked up from the dialogue narration of this weeks guest, and that people are appearing on the Facebook style page, but not actually posting anything - or asking questions.

What was triggered in me was a 'round table' discussion. What I get from the guests is I thoroughly enjoy hearing about their lives, the choices they made in their careers and where this all went.

It seemed to me, as I saw Rex's photo that he is by looks the archetypal American Engineer, the sort that built NASA when Man went to the moon.
In this regard, its almost that I think a round table discussion of such a period between several hams, and it maybe just reminiscing for them.

Instead of focusing on a person, such an approach would come from a different perspective, focusing on an era, where several Hams, talking amongst themselves, could tell their stories of what equipment they used at the time and what they did to monitor things.

Conversly, with a handfull of Contest operators, choosing a period say 1975 to 1980, they may described their stations and equipment and what they were doing. From here we move the period to 1980 to 1985 and hear again where they were now. This would as a section of the hobby show how it was evolving and developing.
It may also lead to some discussion of how people competed with their results in the contest, assessed their station and its strengths and weaknesses etc. I think its almost scary to try and manage such a talk, but then getting four hard core contesters together I think actually you'd have a hard time getting in on the conversation - it would just run itself fueled by their enthusiasm.

What I miss hearing these days is the old timers rag chewing. Just talking amongst themselves and all sorts of odd, funny, useful interesting tthings would come out.

We don't seem to hear this stuff these days, and this is something I've always imagined N2CQR, Bill Meara, and many others, enjoyed listening to, in Bills case on the 75 meter band in full glorious AM.

What you have here Eric, what you've created is a program for consumption by the listener. What the Facebook group is trying to do is make this Interactive, and really, least as I see things, I am not sure it merits interaction.

It is your content that is engaging. The interaction is less so. That is just me.

I really wouldn't mind some advertising in the show related to Ham Radio. Give us some content in here. Not just a name of a company, but something about what's new to them or what they are doing and its a mini story in and of itself.

Its just a germ of a direction, I am not sure where it goes.
If I don't air it with you it will suffocate.

Kind regards

Alex

Wow Alex,

Thanks for your suggestions. They are well thought out. I will try to get these discussions going on the social media as this would make some interesting reading. It is also searchable and therefore would have some historical value in the future. In an era where everything is fast, people really do not take the time to rag chew or have a conversation. On some of the bigger repeater networks, many people are discouraged from talking too long. This is too bad, because I learned a lot as a kid listening to the local repeaters.

Again, thanks for writing and listening.

73, Eric

Hi Rex (W1REX),

So, I built a 14.060 Hamfest Buddy ( Dave Ingram) XMTR. What is the other freq delta, that I hear when I flip the switch? Is it like 14.061 or 14.059? Thanks.
