Re: JackAl Assembly manual
Thanks, Mike. Al and I are so busy with another project, I haven't gotten around to a rewrite of the manual. Jack, W8TEE

Mag Loop activation
All: Al and I will be attending Field Day and will be at the Milford Amateur Radio Club (MARC, W8MRC) at Paxton-Ramsey Park just outside the 275 loop, close to Wards Corner exit. We will be using Al's "Luggable Double-Double" Magnetic Loop antenna, shown here (he doesn't like that name...): You'll notice this version has a vacuum variable capacitor (VVC) for tuning. Also note that Al 3-D printed the mounting brackets (in gray). He even has a thumbscrew clamp on the small driven loop! Tuning is done remotely using two encoders and a NEMA 17 stepper motor with controller. While not finished yet, it looks similar to this: You can see the controller hardware in the background. Test thus far shows it has 13dB gain over a reference dipole. Naw...just kidding. Any ML antenna is a compromise, but for many HOA dwellers, it may be the difference between making and not making contacts. Anyway, if you'd like to see it, come to the Park this weekend. We'd love to see you there! Jack, W8TEE Al, AC8GY |

Re: USB 40M
Hi Rick: First, nice implementation...looks good! Actually, I thought I had that sideband issue anticipated because of the popularity of the digital modes (FT8). I'll check into that and post the fix on the JackAl group. Honestly, it won't be soon as our Hamfest is this weekend and, as an officer of the club, I'm up to my a$$ in alligators right now. Indeed, Al and I will be taking our new mag loop and controller to Field Day, so I likely will not be able to look at it until after FD. Sorry for the delay, but I will get to it. Jack, W8TEE

Hi Jack, I have the JackAl board installed and working quite well except for the hickups in some areas of the software.?

Re: Display Protection Boards
I did not say that mods are "needed", only answering a question that was asked. The "protection mod" is addressed on the JackAl groups' site. I'm sure it's possible to connect a power source incorrectly to a barrel power connector or wire the display incorrectly, but we think fairly unlikely. I believe there have been two cases where someone blew the display, so it can happen, but 99% will never need the mod. It's like life insurance: You hope you never need it, but the risk, no matter how remote, is still lurking in the background. The mod is there for those who want to implement it. Jack, W8TEE

OK nothing yet.? BTW I just saw a message from Jack, W8TEE about needed mods to the current production of these boards.? Does you instructions includce all of those mods? ? 73 jerry NY2KW ?

Re: Display Protection Board.
The board has not been changed, so you should add this on. We will need to work off our inventory before we can add the change. Jack, W8TEE

I have just ordered my board and wondered, are the display protection mods now incorporated in the main PCB or do I have to build this as a separate item / is a additional board supplied? John (G8STW) |

Re: Display size and touch detection
I prefer the 5" as it is large enough to use, but keeps the case size down a bit which may be important for portable operation. Also, the smaller screen does draw a little less power and is less expensive. We prefer the resistive touch screen, as it seems "more accurate" for people like me who have fat fingers. (I'm not fat, I'm just easy to see.) I'm not sure how the library code works with the capacitive touch displays. Jack, W8TEE

Any thoughts on whether the 5" or 7" screen size is better? I would prefer the smaller size I think as there ar more case options but any thoughts from those who have tried either or both?? Much appreciated! Also I think the 7" display comes with either resistive or capacitive sensing as far as I can see.? Could the capacitive sensing option be used with the Jackal board (with an extra interface board perhaps) as it is generally better than resistive? regards Patrick G4MGI |
