Re: New EZ Keyer Kit

Found at least one instruction missing in the on-line assembly manual. Didn't find anywhere a step to install the .1ufd capacitor, C1. An inexperienced or first time kit builder might miss this.
Also Q1 and Q2, the two MOSFET transistors are labeled U2 and U3 on the board's silkscreen. Since the U designation is for IC's and the Q designator for transistors this might confuse some new(er) kit builders.
None of the errata found is earth-shattering, but you guys might want to be prepared to field lots of questions.

Fw: REMINDER - 2013 Iowa QSO Party
WA0ITP
The IAQSO Party is THIS SATURDAY OCTOBER 19, 2013 FROM 1400Z - 2300Z (9AM - 6PM
toggle quoted messageShow quoted text
CENTRAL TIME). Official notice is below my notes. Three new catagories have been added this year - Two QRP QRP catagories, In State QRP Stations and Out Of State QRP Stations, as well as a JOTA catagory. Well known QRP Designer David Cripe, NM0S, is a JOTA vounteer, NM0S will be operating at Camp Waubeek, for both the Mt. Vernon and Lisbon, IA troops. Also Marshall, W0OTM, has added an online Summary & Entry Form, http://www.wa0dx.org/IAQSO/SummaryEntryForm.php He has also added a web page which reports total scores by catagory for the event and is updated in REAL TIME as new entries are submitted! Watch the scores climb. http://www.wa0dx.org/IAQSO/IAQSO_Results.php So fire up the rigs and work the IAQSO Party this Saturday, cu there. ---------------------------------- Real radios weigh less than a pound.

----- Original Message -----
From: W0OTM To: W0OTM Sent: Tuesday, October 15, 2013 4:11 PM Subject: REMINDER - 2013 Iowa QSO Party Radio Amateurs, Reminder that the IAQSO Party is THIS SATURDAY OCTOBER 19, 2013 FROM 1400Z - 2300Z (9AM - 6PM CENTRAL TIME). The purpose of the Iowa QSO Party (IAQSO) is to encourage contact with Iowa amateur radio stations by other Iowa hams and hams worldwide. Stations outside of Iowa work Iowa stations only. Iowa stations work everybody, including other Iowa stations. A complete listing of the contest rules can be found HERE at the 2013 IAQSO Party Homepage. This year we have several exciting changes to the IAQSO Contest Rules: First, we have added two additional Entry Classes for QRP Stations. (Iowa QRP and Out of State QRP) MANY of you have express interest in operating and competing in this class. Second, we have changed the Bonus Points by adding a new feature this year in an effort to support JOTA. The Jamboree-on-the-Air, or JOTA, is an annual Scouting event that uses amateur radio to link Scouts around the world, around the nation, and in your own community. In the IAQSO, 100 Bonus Points (Max 500) will be awarded for EACH JOTA station contact made. As usual the WA0DX - Ottumwa Amateur Radio Club callsign will also be an added 100pt Bonus! In addition, we have a NEW process for submitting your Contest Summary/Entry Sheet and electronic logs. We have developed an automated - ELECTRONIC SUMMARY & LOG SUBMISSION FORM - . This will ensure everyone's entries are process quickly and correctly. Also, once you have submitted your Summary/Entry Sheet, you can follow the scoring process, and see where you rank against other IAQSO Participants by visiting: LIVE 2013 IAQSO PARTY STANDINGS. This page is updated in REAL TIME as new entries are submitted! We look forward to seeing you on the bands this weekend! Have Fun! If you have any questions, please contact IAQSO@WA0DX.ORG.

New EZ Keyer Kit
Bill VanKirk
I received my EZ Keyer kit this morning. I love it! It took less than an hour to build and is a great addition to the shack.
Everything went together well and the case looks very nice. Better than the picture on the Web site. Well done! 72 Bill W0PT

Re: keying circuit
Wayne Dillon
I have a similar set-up. electronic keyer and a rotary switch, however, being the kinda person I am I added jacks at the back of the box for paddle input and straight key, the straight key is parallel with the keyer output. Speed control and memory buttons on the front along with led's to indicate which output I'm switched to and viola. I know, a little over the top but hey, we all march to our own beat right?

Re: keying circuit
davemrtn
I agree, you should not tie all the
grounds together, it can cause problems... been there done that. You can get a 3 pole rotary switch from Jameco and that will allow you to switch 3 circuits.� You'd want to do this if you are using an iambic key. You will need to mount any jacks used on a non-metalic surface to keep the ground circuits isolated from each other.

Re: keying circuit
I'm with WB9DLC. A rotary switch is the way to go. Use one pole for the signal and one for each ground. That is, don't use a common ground. Run a separate ground from each radio. Also, I'd be inclined to use a "break-before- make" rotary rather than a "make- before-break" variety. Best Todd

BUT, I have all the isolation I need inside the electronic keyer. I just want to switch it's output to multiple rigs and not sure if I need anything to protect from RF etc. I'm looking into this for a friend and he wants to use his keyer on 4 seperate rigs without plugging and unplugging. I don't see much of a problem with just switching the output of the keyer. Just curious if I need to protect the circuit in some fashion. 73 Jerry ----- "Nate Bargmann" <n0nb@n0nb.us> wrote:

keying circuit
n0jrn <n0jrn@...>
Gang:
IF you have an electronic keyer and you want to use it with multiple rigs without plugging and unplugging all the time, what circuit would you use to switch between rigs. Electronic keyer would go to the switch and switch to multiple outputs. Doesn't seem like it would take much more than the switch but would you use diodes on the outputs, capacitors on the grounds ?? Just curious. thanks; Jerry N0JRN

Re: New EZ Keyer Kit
A simple errata sheet should take care of it. You might also mention that the washers on the push buttons should go on the underside of the top cover with the nuts on top. Having the washers on the underside of the cover works great to keep the spacing right so no strain is put on the 3 jacks once things are tightened down.
I've done some tech writing in my day and wrote a whole bunch of lesson plans when I taught electronics in the Army back in the 60's, 70's and early 80's so I know how you can have a whole bunch of proof readers check things, but until someone actually uses the instructions to build the device, you won't catch all the errors and maybe not even then, LOL.
Seriously, those were the only errors I could find and I absolutely love the way the case looks made out of the PC board. That is one fine idea and not difficult to put together at all as long as you pay attention to the directions.
I never do unless I run into trouble, and I just use my miter saw's table as a jig and press the bottom and a long side tight to the 90 degree wall & base. It's easy to tack solder the two pieces, swap sides and do the second side the same way. Once the two sides are on the base, the end pieces get done the same way and it all winds up square, no tape needed. The tape/rubber band method is probably the best for those who don't have the tools I do though. No matter how you do it, get it square and it really looks professional.
