S Meter circuit or power out circuit for the Bayou Jumper

KY6R <KY6R@...>
 

I will be building a Bayou Jumper and Souper Upper soon - and would like to add a meter - either an S meter or a power out meter. I'm guessing power out would be easier - but am not sure. This doesn't have to be perfectly accurate - its for "show" - to have a needle move either for RX or TX. 

I guess since its crystal controlled and I will most likely use it to demo on just one or two nearby frequencies - maybe a circuit for the S meter would be best. Even if the circuit is a tap off the audio amp - something to move an old meter - that would be cool.

I'm a software guy - and while I have done a lot of maker projects - and kit projects - I have never designed a circuit before - so I would appreciate some help.

73,

Rich

Oak Hills Research QRP Classic for sale

I have a good condition QRP Classic CL2040 20 and 40 meter transceiver for sale.  I just tested it and it puts out 4 watts. See photos.

I am asking $125.00 + $15.00 shipping.

Any interest please contact me at Djwilcox01 at gmail dot com.

Thank you.

Bayou Jumper for sale

David Wilcox
 


I have had fun using my BJ after I built it a few years ago but now it the time to sell and go on to other kits on the bench.  

Mine is a first edition BJ built in a beautiful Hobby Lobby box along with the Soup'r Up'r kit (unbuilt) and a stock of crystals and items to make your own crystals.  

Please see the photos.

I am asking $125.00 plus $15.00 for shipping via Priority Mail mid sized box.  PayPal please.  Contact me with any questions.  Yes, it does work as per specs but this is a "no return" transaction. One just sold on eBay for this same price without the extras.  I am 100% on eBay but would like to reduce the extra work and their take from my sale price.  PayPal takes their share and the eBay plus PayPal fees eat up the selling price.  I am considering that.  Thank you for listening to my spiel.

Too many radios, too little energy and interest.  I have other kits waiting to be built and enjoyed.  I want this to be enjoyed more by someone else.

Contact me at djwilcox01 at gmail dot com only.  

Thank you.

John -

So are you saying the hum is still present on the dummy load?  Or only
when used on an antenna?

73, Bob W9RAN

PS:   There is not a separate PTT line as in most radios, the N-75
detects the change in voltage that occurs when the mic PTT switch is
closed.  To key the radio w/o the mic you'll need a 4-circuit TRRS plug
- short the sleeve and first ring together.

Re: Finished my Nouveau 75, hum on transmit audio!

Duane Brayton
 

Sorry, I got the other msg first.  In that case mic cord shielding & rf feedback are possibilities. Keying the transmitter without mic attached should resolve that question quickly. You should be able to easily determine the keying line at the mic cord Jack and apply a temporary ground while checking the rf waveform. Let us know how that goes.

Putting it on an antenna has the same result with the hum.
The voltage from the PS's is 13.8.

I'm going to look into it a bit more this weekend, and let  you know if I come up with anything, especially about the power output.

How are you powering the radio & could you have a ground loop?  Is your mic cord shielded? Check these items first.

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.
