Re: It's alive!
Jack Purdum
Hi Greg: Anyone who read my March, 2016, QST article knows how ardent I am about getting young (< 21) people into our hobby. I think my foray into the QRP arena was because I saw it as a way to get into the hobby on a lawnmower budget. The question then becomes: Where does one turn in order to disseminate information to interested, albeit not licensed, people? If you type? "ham radio" into Google, the first entry is the ARRL. The same is true if you type in "ham radio clubs". I don't see a blog anywhere on the first search page. Fame? Even after 18 books and over 30 articles I can walk through any airport in the land and not one person asks me for an autograph! Can you believe it: Neither Oprah nor Ellen have asked me on their show nor have any of the late-night people? I think it's pretty clear if I don't have fame now, it seems unlikely another article's going to do it. The money from writing an article is barely enough to let me Supersize my meal. Nope...fame and money just aren't there and, personally, neither enters into my decision-making process. The real issue is: Where/how do potential young hams gather their information? That's where the review needs to be, as I believe Ashhar has made a tremendous contribution to my goal with the advent of the ?BITX. One area of information for newcomers is likely existing hams, many of whom read QST. Indeed, circulation figures suggest there are many more reading QST than CQ, so that throws the decision towards them. But, CQ can probably get the article out in half the time. Fortunately, the article's not done yet, so I have some time to chew on the problem.

After ordering my uBitx, I was reading Jan 2018 QST , where they had a short article about the Bitx40. They have become irrelevant. Jack, post your article on blogs. Forget paper magazines, unless you like the fame and the few $$ they pay. By the time it's on paper, there will be a new version ;-). My free opinion, and worth just what you paid.

Jack, Great ideas! I am new to the BITX2 talk group.? The popularity of this UBITX rig is unbelievable.? CORRECTION believable. Following this group is very interesting.? I'm in hopes that a video will be produced covering initial unboxing, review and initial build.? It would be invaluable to us less experienced operators to gain information for build do's and dont's up to functioning a basic unit. (Suggested power supply, antenna choices etc.).? Maybe one exists, don't know.? I would think HS Signals would come out with one? Still waiting for mine to be delivered.? Probably after the first of the year now.??? Thanks for sharing your info and experience. Rick Michigan On Dec 15, 2017 9:44 AM, "Jack Purdum via Groups.Io" <jjpurdum=[email protected]> wrote:

Re: Looking forward to a build
Yeah, I am really surprised by the amount of thinking that I've put into an antenna.? It hurt to spend $20 on ferrites for a balun for the dipole (now morphing into OCFD an account of the pending ?BitX), so wire was going to be a challenge to do on the cheap.
Then I remembered the 100 foot extension cord in the garage that I had snagged with the hedge trimmer... |

Don't know if it will help but it may.

Did you do the LPF mod? I had to add the cap on the bottom of the board.

If you have spare IRFs around try this. Slowly increase the final quiescent current and see! Raj Do any of you have a solution ? |

Re: It's alive!

I am trying to get some good pictures of where I think beginners might stumble. For example, I have a blowup of the stereo connectors from the bottom showing the GND, RING, and TIP connections. Same for the volume control and encoder. Al Peter, AC8GY, is a great photographer and I'm trying to get him to shoot the photos. He did this one for me, which shows the ?BITX as it comes out of the box. The more I get into the review, the more I think it needs to be published quickly, so I may go with CQ magazine. QST has a very long lag right now. The downside is the size of the audiences. Still not sure where to try and get it published...

More high res pictures is good also. Thanks. Joel N6ALT |
