Re: Nouveau 75A PTT
Hey John,
Maybe you want to amplify your Nouveau because...
You and your best friend now live out of range of a Nouveau 75, but an amp lets you ragchew reliably. What's better than ragchewing with a

Re: Nauveau 75 no modulation
Measured the signal on mic input and it was RF! Right on TX frequency.
Audio is getting thru but swamped by RF signal.

Re: Nauveau 75 no modulation
More testing
Connected mic on bench to DC pwer thru 1K resistor, shorted PTT and measure 40mV P-P on oscope while talking in normal voice, seems abt right
Tapped into the mic jack on rig, activated

Second Sunday Sprint Results
Based on this month's SSS participation, it's obvious to me that a lot of people are abiding by the "stay at home" directive, and that, as a result, they are spending more time on the radio. We had

Re: Nauveau 75 no modulation
Well about out of hair!
Tried everything still no modulation.
Changed mic element, verified mic cable was ok and pins connected properly.
Out of ideas.
On RX I did notice on very strong signal there

Re: Nouveau 75A PTT
Hello Rex,
I was reading your email and was wondering what is the point of running high power when the Noveau (and the retro 75, I have both) are basically deaf?
When I inquired about this a few

Hi Tim,
There's a good copy of the schematic in the build instructions on pages 14-16: http://www.4sqrp.com/kits/n75/N75NewManual.pdf

Re: Nauveau 75 no modulation
No using condenser mic
I see 2200 ohm resistor across mic output lifted it ant no PTT so there needs to some resistance there
I an going to see what max resistance will trip PTT maybe that will cut

Re: Nauveau 75 no modulation
To be clear, the speaker connection from the speaker-mic is not hooked up inside the radio, only the mic terminal is used. It's on the ring closest to the sleeve and seems to be a non-standard

Re: Nauveau 75 no modulation
This is how mine is wired. Are you thinking we’re using the speaker as a dynamic mic of sorts instead of the electret and that’s why we have to crank the gain all the way up and shout?

Re: Nauveau 75 no modulation
Hi Tim! Finished my N75a yesterday. I had the same issue and thought I had a bad mic until I maxed out the mic gain and talked very loud in the mic. Even at 90% mic gain there is zero audio but turn

Re: Nauveau 75 no modulation
With the stock microphone, I'm having to crank up the mic gain all the way to get the LED to flicker. Also noticing a lot of hum on the audio (even though using a regulated power supply).

I don’t have a better copy. Perhaps contacting the kitter or a member of 4sqrp leadership to obtain a clearer schematic.

Re: Nauveau 75 no modulation
took back off mic and there is something wrong with wiring!
is there a clearer schematic for rig? when I view the one on 4sqrp site it is blurry

Tim,
This is Tim, K0EMP.
I also had a similar experience. Turned out I had a short in the mic cable just below the mic head. I suggest you check the mic writing first and if that is not it that you

Re: Nauveau 75 no modulation
Tim,
Check your microphone, it’s not a high dollar microphone. Mine was wired wrong. The speaker was wired to the tip and the electret was on the ring ground was the sleeve.

Nauveau 75 no modulation
Nice 5 watt carrier but I get no modulation with MIc.
PTT on mic is very stiff but I do not think that is a problem.
Anyone else have that issue before I drag out Oscope!
