Charles W. Powell
 

Thanks for the information Bob.  I have heard a lot of activity on 75m AM because I often just turn on the radio when I'm in the shack.  I'll have to pull out the Hardrock 50 if I really want to be heard.  The HR-50 should be fine because you can over-drive it beyond its specifications and the only worry is overheating.  As long as you watch the temp, it will be fine.  I think it's pretty heavily under-spec for what the finals can do.  

I figure that most of the stations won't hear me even if I try running barefoot.  I was surprised that Johnny and I couldn't work this evening because he was S9+20 on the CW net.  But then that's the difference between CW and AM.  I think it also might help if I put up a true NVIS antenna, like a horizontal loop in the back yard.  I have just enough room, so it's a matter of putting up some supports.  Anyway, the N-75 has been a surprisingly fun little project.

Well 40 meters was weak at its best!
Check in's on 40 meters were:
KD0WF
and a partial call?
possibly WB0QQT?

80 Meters was a lot better.
Check in's were:

WA9PWP PAUL
NK80 CHARLES
WN0WWY DALE
and
WB0QQT

We had some qrm from the NA sprint so I moved up to 3.564.5 to avoid the qrm.

Check in's for the DMR net were:
WA9BNZ BILL
N0TGR DICK
NK8O CHARLES
WA8NWA MIKE
N9OJR ERIC
N9PUZ TIM
WW9H JIM
WG5F ED
K0EMT BRIAN
KC0IFQ DENNIS

Thanks for the check in's everyone, I hope you have a wonderful and
safe Thanksgiving!

Charlie, if you're around check 3880 next Wed. night starting at 5PM your time, for the Mighty Elmac Net.    Net control is WA6GYC out of the Detroit area and you should be able to hear him at least until the band goes long.   It was fading after about 1/2 hour when I checked in with my Nouveau 75 aided by a single sweep-tube amplifier running about 20 watts carrier, but Rex heard me better than I was hearing him at the time.   He just got his N-75 kit so there will be others on the net soon.

The Elmac net has moved up a couple of hours due to 75 meter propagation, but meets each Wed. on 3880 except the first Wed. of the month when the Collins Collectors AM Net take over, and you'll get to hear lots of "tall ship" AM stations then.

I have the Hilltopper 40 out for 40 meters tonight but I suspect it will be quite long.  The bands have been pretty exceptional today - I picked up several 10 DX stations, and had a little rag chew with two different stations on 60m in the middle of the afternoon.  First on Channel 1 and the second o Channel 2.  But we shall see how it goes.

I was listening Charles.
The guys up at 3885 pretty well had me covered up at 3875.
Man they are sure strong?

40 was really long last night during the fox hunts, I worked CA.

Cu all at 8:00 8:30 and 9:00.
I am the only lonely NCS tonight!

John, First off I'd check your power supply.    A scope would be the best tool but if you have a different supply that you could try, that should verify.   The next thing is a possible ground loop - if you can, try a battery or disconnect the antenna and put the N-75 on a dummy load that is not grounded.

Your output does sound low - mine has about 3 watts resting carrier and when I posed the question a  while ago no one replied to say they were getting 5 watts unmodulated carrier output.   The power supply voltage could easily make up the difference, mine is running at 13.5VDC.

Are you using a metal mic? where the hum can come from your
body and into the radio via your Mic?

Greetings,

I finished my Nouveau 75 last night.
The receiver works fine, with nice audio. The sensitivity seems right in line with other comments that I have seen.

The transmitter puts out 2 watts; up to 6 watts with audio into a dummy load.
Although this is a bit low, none of the components are getting warm.


One issue that I have having is that there is a low level hum on the transmitted audio.
The hum is consistent regardless of the audio gain setting.
Other than that, the transmitted audio sounds FB.


Can anyone give me some advice on troubleshooting the audio hum issue?

Also, any comments about the low wattage? (I'm thinking right now if it ain't broke don't fix it!)

Thanks and 73, John W4JPL

P.S. I made some notes about building the rig, including mounting that pesky daughter board; if anyone is interested, I'll post them.

Re: 40 and 80 meter net report

Charles W. Powell
 

Yes, Fernan, that is exactly what it means. Depending on the time of day and the ionospheric conditions, 40 meters can be short - conducive to hops ranging from a few miles to a few hundred miles, or thousands of miles. So when 40 meters is “long” you are more likely to have contacts of 1000 miles (1600 km) or more and less likely to be able to work a station 100-200 miles (160 to 320 km) away. 80 meters can behave exactly the same way. One night I was hearing absolutely nothing on 80 meters, except one station mid-band. It was Western Sahara, and I worked him with 5 watts on 80m. That is unusual, but it certainly happens.
