Isn't a BC221 a Frequency standard.  You modified that?

Getting ready for Winter Field Day,

Winter Field Day is Jan 30/31.
Still freezing here w/ much snow.

Time: 1800z, (1300 EST).

Freq: 7032 kHz +/- 2.

i will be using my modified BC221 at 8 watts on 40 meters..
Then at 1900z,  i will be on 14061 kHz, +/- 2,
Later on 14285 +/- 5 SSB.

Read all about the Las Brisas Observatory 

(Ice Station Zebra  is the Administration Building on the left).


The QSL card for this operation will be of the BC221 QRP Radio.

Johnny:

To tell  you the truth, I haven't looked yet.  I've got plumbers and tuckpointers running all around my house and I had to take my wife to PT.  Now I'm headed to the doctor for my 6 month checkup (required for the extended warranty-hi).

I'll take your word for it.  Glad to hear things are starting off with a bang.  I'll check tomorrow night when I tabulate everything.

Re: Possible Bayou Jumper operating event

Jim, N5IB
 

Gang,

I'm going to take all further posts from me of this event over to the Bayou Jumper Group, so if you're not signed up there and want to keep tabs, join up at
https://4sqrp.groups.io/g/BayouJumperKit
That'll save this list from the clutter of cross-postings

We have at least one possible "London" volunteer.
In Houston, so not as central as I'd like. But he's decidely QRO, and an SKCC Senator.
Still receptive to a more centrally located op if you have a recommendation.
I think we shall treat Jan 20 as a short test run, say for an hour or so, and then work on gearing up for another longer go on Mar 15 for Eileen Nearne's 100th birthday.

Jan 20 plan will be for "London" to CQ and work "spies" for an hour, then QRX while the spies try to work each other.
I think for an added twist, we'll have our 'messages personnels' be sent **in French**
....... "les moutons sont dans la grange" ....... "laissez le bon temps rouler" .......
That'll make the troops clamp the 'phones on tighter :^))

So make plans to be QRV 0100 - 0300 on 20 Jan 2021 UTC (that'll be the evening of the 19th in CONUS)

Remember - go to the Bayou Jumper group for updates.

Jim, N5IB

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.

Re: Possible Bayou Jumper operating event

Jim, N5IB
 

Hi Curt,

I hadn't even thought about "London" being on SSB !
What fun ..... hey ( evil grin ) what about working on.... wait for it.... 7126 kHz, upper sideband ??!
That'd give some of the 40m denizens something to chew on.

So far haven't scared up any volunteers for "London"
May have to push the date back some, which would give more time for a bunch of newly minted Bayou Jumpers to get checked out.
My station, I'm afraid, really doesn't have enough uumph to be "London" and I'm not very centrally located, but might consider doing it as a test run on the 20th

There are some more more significant SOE/SIS birthdays approaching:

Jan 30 1890: Major General Sir Stewart Graham Menzies, KCB KCMG DSO MC
He was "C" - heading SIS during WW2

Mar 15 1921 Eileen Mary "Didi" Nearne, MBE Croix deGuerre
She was a wireless operator for SOE
Escaped from the Gestapo and lived 'till 2010
Her sister and brother also were SOE agents
her 100th birthday approaching - she'd be a great one to honor

April 1 1890: Sir Mansfield George Smith-Cumming, KCMG CB
Head of SIS, he was the very first to sign his documents with "C"

April 6 1906: Virginia Hall Goillot, DSC MBE Croix deGuerre
An American working for both the SOE and OSS
known to the Gestapo as "the limping lady" because she'd lost a leg in a pre-war accident

  I'm in! Sounds like fantastic fun. Who will be the "London YL"? Is that a secret, too?

Re: Possible Bayou Jumper operating event

Curt
 

Yeah it would sure freak some out to have 'London' as a YL or a small network on 40m ssb just above there working the BJ stations working split, maybe with a qro cw hanging around if help is needed to clear 7122. Yep they could say this is London, of course with legit ID.

Have fun. I don't have a one box BJ, but a smoking WBR regen available with a transmitter similar to the prototype, a tuna tin 2 cascaded with a irf510 lurking. These would be good modules for a mark 2 BJ.
