Finally got my rig into a case

 

Group,


I finally have gotten my radio into a case. ?I added a hi-per-mite cw filter. ?I can turn the cw filter on and off with my menu system. ?That hi-per-mite is a very nice filter. ?I'm amazed at how well it works. ?It has completely transformed the receiver in this radio.


I also added a K6XX zero beat indicator which is also working well. ?I put one of these in all of my QRP rigs I build. ?It won't stop you from zero beating to the wrong image of the signal. ?But, once you understand how this radio works, that is pretty easy to avoid.


I did all of the cuts on the case last weekend. ?I wired things together all day yesterday. ?I finished up about 10:00 pm. ?I double checked my work all morning and then fired it up about noon. ?Everything worked perfectly the first time. ?This afternoon I added the menu item in the software that lets me turn the cw filter on and off. ?The difference when cutting the filter in and out is amazing.


I've already gotten a QSO in. i used my Bencher paddles with the keyer in my software. ?I had about a 20 minute QSO with a ham in OH. ?What a fun little radio. ?


Thanks everyone. ?I've learned a lot from all of your contributions.


I created a photo album called K4KRW's Build. ?I put a couple of pictures in there. ?I'll be adding some more later.

I just got my first DX contact with my radio. ?Bert F6HKA was getting SKCC contacts on 40m tonight and I got him. ?2 Watts. ?He gave me a 579. ?What fun.

He was on 7.055.

Richard - K4KRW
 

That is SUPER! You should write to QST and tell them. I'll bet it would find its way into print.

Jack,

I actually got the QSO on video. ?I was working on a demo video when i heard him.

Write it up and send the video...definitely a good shot at getting it in. Frame it from the point of view that you don't need to be rich to enjoy our hobby, sorta like I did with the 49er article and the young boy at the GOTA station.

Jack,

That contact with F6HKA comes in at a little over 2000 miles per watt. ?This is why I love QRP and CW. ?There are lots of great projects out there for building these kinds of rigs. ?Molding them to meet your desires is a lot of fun. Groups like this one make it all even more enjoyable. ?Then, it all just works so well. ?

The March QST article really set the hook for me. ?I actually wasn't sure when I started this project just how usable this rig would be. ?It just looked like a fun project. ?This is the first direct conversion rig I've ever used. ?This was my first time to write code for an Arduino. ?This was even my first time to write code for a ham project of any kind. ?I have had a ball. ?And even with the rig being direct conversion I find that I really like it.?

I did have to add some extras to get here. ?The CW filter I added (Hi-Per-Mite from the Four States QRP group) is fabulous. ?I added a BCI filter as well. ?Finding my way through all of this has been half the fun. ??And now I am truly enjoying my completed rig.

Thanks so much to you, Farrukh and Dennis for lighting this fire. ?

Thanks for the kind words. 2000 miles/watt is one of the highest I've heard. Again, write it up and put in about the BCI and CW filter. Indeed, mention the Four States group explicitly...it might help drive some sales their way. Did you use the BCI filter I wrote about? Did you use my C book for any of the programming? Finally, do check out the BITX40...it's pretty neat!

Thanks again for all your help in loading your software on my radio.....its working well although I cooked the final....got to look at the SWR again.

I was wondering if on your next software version IF you would consider moving the keyer speed from the .h file to the menu. Not sure if you have any room left. I think the last time I complied your code it was something like 68% on 1.8.0...If not,,,no big deal I can get around it.

thanks again

Don,

That keyer speed in the SCRadioConstants.h file is just the default value the first time you start the rig. ?From then on it should use whatever you select. ?It saves the speed in EEPROM so it should be that same speed you used before when you restart the rig.

The first menu option is the keyer speed. ?Are you running the latest version? ?1.0.3?

Thanks,

Richard - K4KRW
 

ohhhhh jezzzzzzzzz whats the mater with me ????????....yeah I see it now...somehow I jump right over that selection when I'm in the menu.....I'm on massive quantities of drugs for a sinus infection....that's my story and I'm sticking to it...

Love your software....hope you'll post your newest one with the filter.

Don,

No problem. ?It can happen to anyone. ?I'm glad you like the software. ?I need to work on the code for turning the CW filter on and off. ?I want to refactor it to generalize it so the class can be reused for anything that needs to be turned on and off via one of the ports.

Now that I can actually use mine, I found one small bug I have already fixed in mine. ?It was only refreshing the voltage on the main display when the voltage actually changed. ?When you come back from the menu or RIT the voltage would then not display unless the voltage changed. ?So with a stable power supply it never re-appeared.

Hi Richard.

Funny you should mention the voltage reading....I was playing on 40m last night and I noticed that the voltage was jumping around. I never noticed the voltage reading up when I was transmitting before.

So I jumpered the 49er key line and saw the voltage dropped 1V on xmit. Got a regulated PS on the input and that was steady.....I think I used a DuPont jumper somewhere where I should have put a heavier wire. Got to check that out today.
