Ron W2CTX sent me some documentation, I am set.   Please enjoy some time off! 

yes I just learned I need to add my callsign to my marker here - I guess indeed our email is invisible.

The tech support from the designer and seller are excellent.  But if they don't know, others building and using will find out.  Perhaps build it, use with an old PC, and later integrate the soundcard.

Re: Calibration #calibration

d.maccallum@...
 

Attached is my calibration spreadsheet calculator, I use a free office app called Open Office.

It looks like it's gonna work,,,,will test it this week end....but maybe you can check it out and let me know if it's right?

I have a good comm receiver to measure my mbitx freq. output. My mbitx is transmitting 5 watts into a 50 ohm 15 watt dummy load. The comm RX has a 1 ft wire antenna with 40 db of attenuation cranked into it.

OK fer now CU all Later 73

What is your experience with drivers for this external card on Windows XP and/or 10?  Immediate integration of USB connectivity to the board seems like a good way to neaten up a final product and minimize connections to have to fiddle with in the field.

I'm not really faulting you for using a mnemonic that was a product of the times, but this is a case where litterally anything else would be just as good and "not politically correct" ends up meaning something more like "makes the hobby just that little bit less inclusive, for no benefit in particular". Wikipedia offers a whole page of alternatives.

Update: adding a 4.7k resister between the ptt pin and the 5v pin solced the problem for me.

Vic, I seem to have found an old set of posts by you where you talked about your issue and fix. Did you end up disconnecting the built in pull up resistor? The value you quoted makes me think you added to it rather than replaced it.

Re: Gordon Gibby Digital Interface

 

Not yet I only tend to do pre-orders to help get a kit going after that I try not to do that. It can get a little nuts being a one man show and having tons of pre-orders to fill while still having time for the kids and family.

Thanks for the suggestions, everyone.

Vic, your issue sounds the most like mine of the things I haven't at least tenatively rulled out. I notice that I am confused, though. If the resistor wasn't adequate, shouldn't it go into ptt even without the mic like it would without the one for the key socket?

Curt,

 I need a call sign to look you up :-). Waiting on Isolation transformer's to get here and more will be ready as well.

John KC9ON is almost around the block from me, we are both members/officers of the Top of Michigan Amateur Radio Club.

Good person to talk to and has taught me a lot about kitting.

Not all mike jacks are built the same.  A quick check might be to use your ohm meter to verify that mike jack conections are going to the proper pads on the PCB.  After verifying jack-to-board connections then apply power and use your VOM to verify that voltages are correct for each lead.  

Insert a new mike plug (no mike cable) to see if the problem might be in the jack.

If the shield connection is not grounded the PTT and mike audio will interact.  This usually happens it the jack is installed on a plastic panel and the shield connection is not connected to circuit ground.  

Might also be a wiring problem in the mike plug, cable, or in the mike itself.

You could connect only the ground and mice audio, leaving the PTT unconnected to check if the problem involves the audio path or the PTT circuit.

I appreciate what you are doing, sure email me a manual if you have time to grab my email from qrz.  I plan to order in the next batch, if I catch it in time (that is all on me).  Everyone needs to appreciate the ability to purchase things via your store and others who are willing to take the time for us.  Don't know if you know KC9ON that has been active selling things to the QRP community?  We can always hope for merchants on each continent to serve us across the globe. 

I was looking for someone who had reviewed your paddle - maybe I just need to try one.  I use W5JH paddles, a large one in the shack and a small one in the bag - but I should play with something smaller.

PS - I knew of Gordon's nice relay board because our club did our kitting of them - glad you are making them available and I hope sales increase - its a clear winner on curing the harmonics

Did you check the micro switch to be sure it isn't always closed?

Sounds like the connector is failing.

Re: Gordon Gibby Digital Interface

 

Trust me its not by choice on the manuals. The site layout/opencart that I use will not let me post the manuals I have to link them to sales. Its also why I say send me a mail and I will send them out. I have sent Dennis the info and Curt if you would like it let me know at n8dah@... and I can send them over. If I could post them on the product page I would but opencart will not let me.
