W6SFM Bug Roundup Event is coming soon! Save the Date

SFMARC W6SFM
 

Announcing W6SFM's BUG ROUNDUP

The Samuel F. Morse Amateur Radio Club, a Sacramento, California based CW enthusiast club wanted a special time to bring bug operators together on the air. In the same spirit as ARRL's Straight Key Night, participants are encouraged to make simple, conversational, “chewing-the-fat” QSOs using their bug type key. This is an opportunity to exercise, share and exhibit your personalized fist. This is NOT a contest. However, there is a very easy and quick registration form found at https://w6sfm.com/bug-roundup/. Once you've optionally registered for the event simply Call "CQ BR" so folks know you are a Bug Roundup Participant.  So lets grab that bug, clean those contacts, and let’er fly! We want to hear that “Banana Boat / Lake Erie Swing" or that commercial KPH/WCC quality fist on-the-air.

Reserve the date! The event begins on Friday November 15th (00:00 UTC) and concludes Sunday November 17th (00:00 UTC)
That's 4:00 PM Friday evening until  4 PM Pacific Time (LOCAL)

For more information, to register your station, and to help assist in spotting, potentially increasing QSOs, an On-line chat window link can be found near the bottom of Bug Roundup home page located at  https://w6sfm.com/bug-roundup/  We hope to hear you all on the air! 73,

W6SFM

Excellent work.  I'll make the modification on my rig also, to confirm no bad second-order effects.

We have a change in NCS for the 40 
Meter net tonight.

Bert N0YJ will call the 40 meter Net at 
8:00 pm central Standard time.

I hope to be home in time for the 80 meter net at 8:30, tonight is my monthly civic duty with out rural water group.

Re: Freq-Mite

Joe Street
 

Or if the production is stopped is there any chance to get the code so that a person could burn thier own chip?  Even a hex file would be a blessing for anyone who has a failure or wants to press on with an old design.  I found a bare board for the venerable NC2030 that requires the freq-mite for example. I went looking for this but came up empty too.

Re: nouveau 75 Dave Cripe/Voltage Checks

W9GY <jeffw9gy@...>
 

I've made some progress on Q11 overheating, and 'crud' in the modulation on this unit.  Various bypass capacitors on Q11 seemed to help, but I didn't think that the FET was cool enough and the envelope didn't seem as clean as it should be.  So I decided to take a look at why the device was running with so much current.  To make a long story short, I paralleled R43 with a 470 ohm resistor. This lowered the drive to Q12 and thus reduced the excessive current through Q11.  Now the transistor runs cool.  There appears to still be sufficient modulation capability in both directions, and the spurious signals now appear to be gone.

Re: nouveau 75 Dave Cripe/Voltage Checks

W9GY <jeffw9gy@...>
 

I bypassed the gate of Q11 with a 1 MFD electrolytic as suggested by Bob, W9RAN.  I now get  modulation envelope above and below the unmodulated carrier, which is what I would expect.  However, the device is still running too hot.  More later...

Re: nouveau 75 Dave Cripe/Voltage Checks

nm0s_qrp <ai9e_qrp@...>
 

Bob, that seems like a good insight.  I have a suspicion that there may be an underlying cause, possibly a manufacturing issue causing the small SMT transistors to leak.  My operating theory is that there may be some solder paste under the SMT parts that is allowing some current leakage.  This would cause Q12 and Q11 to be turned on simultaneously, resulting in the high dissipation you observed, and may cause the oscillations you are seeing.  I'm going to do some checking to see what I can find.


Re: Nouveau 75 power output

Charles W. Powell
 

That seems to be about what mine puts out, but it made a perfectly fine AM contact with it the other day with it. Remember, that’s less than 3 dB down from the advertised level and it doesn’t make that much difference in your transmitted signal. The receiver doesn’t seem to be wildly sensitive, but I think if it were I think it would overload. I set my modulation by the LED activity, with it flashing only on peaks. WTWW (5085) sounds great, as does the net that meets on 3885. I don’t think I will mess with mine. The enemy of good is better!

With a 13.5VDC supply I get 2.8 watts resting carrier and right at 11 watts PEP on voice peaks with 100% modulation. That was good enough to be heard around the midwest this morning on the Midwest Classic Radio Net, but it's about half of what the Nouveau 75 specification says it should be.

Some comparisons will help determine whether my modulator is still not working right, thanks.

Re: Nouveau 75 power output

Bob,
I tried to answer you direct however my email was returned. My Nouveau 75 is making 5 watts carrier and modulates to about 12 watts. It seems to work well and the receive sounds very good with an external speaker. The internal speaker not so much. In the evenings I have been using it to listen to WTWW on 5.085mhz. It receives that station very well.

QRpometer Power Readings

George Privett
 

Hello,

I just received and built a QRPometer. It is a 1st class kit. It is not my first kit, but I have not built many. The board is one of the best I have seen and everything fits as it should.  The SWR readings are perfect the power readings on several QRP rigs give a good comparison between the rigs, but I am not sure if they are correct, and if I assembled something incorrectly. Here are my readings:
Cricket 40 @9v - reading 0.13, @11.5v - reading 0.20
Pixie 2 @9v - reading 0.09, @11.5v - reading 0.15
ATS-3B @9v - reading 0.23, @10v - reading 0.35, @11.5v - reading 0.40
I also tested an Elecraft K2 and IC-7300 with power from 0 to about 12 - the readings went up then down, but did not seem close to what the radio meters were showing

I did re-solder the pads on the Velleman meter, but perhaps this is not correct.

Thanks

George VY1GP
