Hi Tim,

Since you're not hearing any peak in background noise or signal when making adjustments, it's probably something in the LC Tee network, rather than in the SWR bridge or indicator circuit.

First question... is there any change in background noise when you switch from "IN" to "OUT" ?

Second... measuring from the top of L1 to ground with an ohm meter, is there essentially a DC short (~ zero ohms) for ***every*** position of SW1 ?

Third... measuring from J1-1 to J2-1 with the SWR bridge "OUT" do you see an open circuit condition ? With the bridge "IN" do you see a few ohms ?

Fourth... do you have any instrument capable of measuring capacitance in the tens to hundred of pF range ? If so, can you check C1 and C2 that they do in fact vary from a couple of tens of pF up to their max of 250 pF

Very unusual for a tuner not to work at all, unless wire is way to short. Check that connections are real with a dvm, once myself I experienced a connector solder joint that wasn't real but open.

Try on different bands, like 80m which has more noise.

Re: Question about 4S Tuner

John Lonigro
 

Tim:
The tuner has two distinct parts.  If you are using it with a receiver, the only functional parts are the two switches (SW1 and SW2), the two variable capacitors (C1 and C2), and the inductor (L1).  Without a transmitter, the other part won't work.  For one thing, that part gets its power from the transmitter's RF - no RF, no power.

So all you have to check are the components I mentioned, as well as the connectors J2 (input from radio) and J1 or ( J3 and J4).

The first thing I'd do is toggle the IN/OUT switch to OUT and keep it there.  The "IN" position only works with a transmitter attached to J2.  That may have been your problem.  Tune in a station, then rotate C1, C2, and L1 to see if there's any change in signal strength.  Don't look at the LEDs.  They won't light.  If you get no change, you need to check your wiring on those components.

Good luck and 72,
John, AA0VE

Hi Everyone ....

A bit off-topic perhaps and i apologise to the group list moderators

Im asking here as i know some of you will have done this on occasion for yourself

Myself and my family tried to find out the current correct QRP ARCI officer and procedure again to purchase the dvd in the subject heading for christmas there

Alas this was  to no avail with no answers to my sisters enquires to the toystore

I would very much still like to have the updated dvd   I always have this same trouble each time we try to order this dvd

Perhaps its due to the fact i have a qth in Scotland - United Kingdom

And NOT The U.S.A  or Canada ??

Can some help my family get the show on the road happenin with this for me by assistance somehow ?

Thankyou

Re: For what is a crystal spotter used?

 

Jim

With regards to spotting I also was never able to use the key down in RX to spot my frequency. As you mention the heterodyne is widely spaced and not very loud. By accident one day I tried using my Whiterook mini keyer (Tick-2 ) in the straight key mode. Without touching my regen or atten I now get a loud heterodyne with a small dead spot. I have no problem spotting almost exactly on 700 Hz.
It works great but I don’t know why. I’d be happy to take some measurements if anyone is interested. The only mod I have is the TIP42g transistor for the external keyer.

The question asked was, "why not just power the Bayou Jumper's oscillator, but not the PA, and just listen for the signal in the receiver?"

The answer is - The Bayou Jumper does in fact work exactly that way. When you press the key while in the receive mode, the oscillator is activated, but not the PA. It was designed to do that. The signal can be heard in the receiver. Great, just what's needed, right ?!

Well, not so much....

Remember, the receiver is a regen. That means that any strong signal will pull the receiver onto the signal frequency. And remember that the source of that signal (many many millivolts) is right on the same PC board, just a few cm away from the detector. The zero beat "point" on the dial ends up being a broad region, with no some strong over a fair amount of dial in the middle and squeals on either side.

Now, if you run the regeneration control all the way to max, run the attenuation all the way to max attenuation, and turn the AF gain way down, you can sometimes just about get away with it. But then you have to reset everything back to normal receiving. Much simpler to have a little oscillator sitting next to the rig. Touch the crystal to it, and a clearly discernible, but not overly strong, signal can be heard. Tune to zero beat, pop the crystal back in the rig (maybe mark the dial) and you're ready to roll. You'll hear everything with three of four kHz of the zero beat point.

Bottom line, there's just not an easy way to knock down the signal strength of the internal oscillator to the point where it will play nice with a regen detector. BTW - the original Paraset couldn't spot it's own signal either. The B+ was switched off the receiver during transmit. But, they didn't have to. They knew where to listen for London (definitely QRO!) , and London knew what crystals they had.

BTW - When David designed the Soup'er Up'er he had to fight that problem to get a working sidetone. The audio amp had to still be powered during Tx, but he had to knock down the Rx output with a MOSFET switch.

I'll second the return of the freq-mite. I seem to use it on anything that doesn't have a dial or digital readout. Although I am sitting here thinking about the crystal spotter in an HW-8 has a dial calibrator.

Calling all Agents...

How's this for an event to simulate how it was done "back in the day"

We recruit a QRO station (biiiiiig  honkin'  leenyar)  to be "London"
"London" sits down on, say 7105 kHz, and calls CQ
Bayou Jumpers plug in their 7122 rocks and try to work "London"
"London" has to tune all around 7122 to find those Jumpers in their  cute little QRP pileup.

Maybe "London" sends a unique BBC-style "message for our friends…" to each caller
  e.g. "Jean has a long mustache"   "the porridge is cold"  etc

Certificate or QSL to each agent who copies successfully.
Extra Spam ration coupon to "London" for the effort.
For more realism, "London" ought to be a YL

How many Bayou Jumpers could we get to congregate?
Could we find a way for those poor, Jumperless, QRPers to join in?
