Re: 40 meter hilltopper little rf outpt.q

Hi David, 

Tnx for the reply. 

On close examination I found that U4 was missing and looking in the parts box there it was. After a quick install, problem solved. 

I found that voltages were listed on the schematics at key points in the circuit. That would have been my next step. 

I'm using the 3d printed paddle I got from you at Dayton. It's working well. 

I'm putting together a Vectronics 40 mtr qrp xmtr to go with the ZZRX 40 that the Mich State Univ ARC built as a project 
this year. We also built a couple of QCX's. What an amazing rig that is. We combined the audio and radio clubs at W8SH
and attracted 13 newly licensed hams. They love building radio and audio stuff. This very important for engineering students. 

I'll look for you on the radio. 

Tnx and 73,

Re: 40 meter hilltopper little rf outpt.q

 

Ed,

 Sorry to hear about the low/no power out.

I would start with checking L5 and the BS170's.

After that try checking the LPF stage C47,48, 49, 50, 52 and L6 and 7 to see if anything has cold solder joints. Also check L5, 6 and 7 for continuity.

I am in the middle of build a HT20 (5th one) and once I get it done I can check voltages for you if not solved by then.

Whoa!, hello Charles, thanks for the tip. This forum is a great resource for info. They had a big field day this 
past weekend, and my son's radio worked great - buy my little hilltoper no worky.  and my text above, typos! file=fine!!

I will give it a shot.
Thanks,

Transmitted using a 20 m 1/2w dipole. The xmit sig sounds file a few hundred feet away.

But sadly the receiver seems not to work well. Are there any other parts that

 Worked! thanks I knew it was the lib version. I have been working on other projects and I am sure got mixed up with versions.

Thanks for the code, reply and help!

Re: HT-20 Hilltopper

Charles W. Powell
 

The version you need for this particular application is Etherkit Si5351 version 2.0.1.  The error you are getting is consistent with a newer version of that library.  Dave (Benson) never updated the library version - if it works, don’t fix it!  I don’t know enough about programming to re-write it for a newer version.

Hope this fixes the problem!

I have to wonder if this is a configuration issue, either with the Arduino version or more likely, NT7S's library element.

Martin,

I don’t have a “fix” for this, but I had that happen with a chip I substituted, where the frequency was off by a considerable amount.  As I recall, I did not end up using that chip, but apparently there is a bit that is set that puts the frequency off by a substantial amount.

Of note, if you flash the original chip with new firmware after the initial configuration is set, all those settings will be saved (frequency correction, iambic A or B, and paddle reverse).

Dave, K1SWL, who wrote the original code may have a “quick” correction or be able to give you advice on this problem.

I had the Hilltopper-40_V2.0 firmware loaded on a second ATMEGA chip to experiment with my HT 40m. In TX or Calibration mode, the output frequency is 7.580 MHz, not the expected 7.030 MHz.
It is the original file that was downloaded here.
I can not find my mistake.

Can someone check that?

Re: Hilltopper 40m firmware

Martin,

 

I have about a dozen versions of the Hilltopper code. The attached file allows specifying the band (20, 30, 40) in a single line near the top. Band-specific constants are computed from this single specification and are therefore easy to find in this version.

 

In other versions, the sketch has been modified to support a limited CAT interface for tuning (and RIT offset tuning) using Ham Radio Deluxe, and/or for frequency display using an attached LCD or OLED device (described near the end of the page at http://lloydm.net/Demos/Hilltopper-20.html).  I am glad to share any of this.

Hey guys had to share this.

STL files will be uploaded (work in progress) open for all to use just share any changes.

I trimmed the I2C interface right down to the lcd, no header, I also removed the back light jumper and bridged it.

Some notes on the STL:

Done with tinkercad

uses stock screws spacing is a hair tight and may need to use a razor to bring it in (always better to have to much, hard to add it back).

LCD opening was left with no screw holes to open all options of mounting.

LCD opening is also a little tight to make up for vari in screens again going with more it better.

I got a nice fit and used the screen to make holes for screws, it was a tight fit but I didn't want to add more than was needed.
