I tried to make myself be known. I am new to nets on CW. Can someone tell me the procedure?  I gave my call several times. I'm only comfortable at 12 wpm.  I did hear WA0ITP, N4DR, WA9PWP.  Then I heard WB4IEA talking to W2TAW. 

I was on my Pixie (400 milliwatts) then tried my Bayou Jumper.

bayou jumper no tx

ken cubilo@gmail.com
 

Not sure if this is the right place to post this but, I recently finished up the Bayou Jumper kit although the receiver is working great I cannot get the transmitter to generate RF no matter what I do. I have been doing this stuff for over 50 years now and am very surprised a circuit with what maybe a dozen parts is kicking my butt.  I have checked and replaced the osc and final transistors, tried no less than 6 different 40 meter crystals verified part values both installed and actual. Voltages measured are what is specified maybre just a tad higher as my power supply runs closer to 13.8vdc, but I have tried 12vdc as well.  Verified switch is working right and correct paths are being switched but still the oscillator will not sing. Years ago I build an elecraft k2 and was having a problem with communication to the ssb module I did find a microscopic ground across traces on the board causing it. I guess now my next path time permitting is to trace back the board a bit and see.  If anyone has a magic wand please feel free to use it.

Hi Ken,

We've had some reports of the Tx section of the Bayou Jumper giving troubles, and in at least a few cases the trail led to the final transistor Q4 (IRF-510).
It appears that certain "flavors" of the IRF-510 present too great a load to the oscillator stage (Q5) and prevent it from oscillating.

I've tested samples froma few different batches, and at this point I'm pretty sure that IRF-510 transistors that are marked ""Y64K AP" work reasonably well at Q4, but those marked "618 P 77 WS" would kill the oscillator. Some new IRF-510s bought from Mouser (Mouser #844-IRF510PBF, factory marked "N77K BJ") also worked.

You can check if the Q5 oscillator works with Q4 out of the circuit, but quits when Q4 is connected.

Doesn't matter what sort of IRF-510 goes at Q6 - that's just DC service.

Mine failed to work because my old eyes allowed me to swap capacitors. I ended up using a USB microscope to read them, swap two and it worked great.

Re: bayou jumper no tx

ken cubilo@gmail.com
 

You are correct. Last week I ordered some IRF-510 transistors from mouser and they just arrived this morning. result the Bayou Jumper now generates 6 watts of rf power into the antenna. I did check on the supplied transistor and it was indeed stamped 618p77ws.
thanks to everyone for the suggestions and now on to install the souper upper. Hope to catch you guys on the air

Re: 40m Net - Holy Cow !!!

Hi Wayne,
 
Well, the procedure is to send your call when the NCS (Net Control Station) asks for check-ins with "QNI ? k".
The NCS will then take a list of calling stations that he hears, ask them to "PSE AS" (please wait) to signify that and then ask for more QNIs.
If you weren't heard the first time, try again.
That means you are on the list and will be called in order.
If the NCS doesn't hear you, someone else may have and should offer to relay your information when the NCS asks for relays with "Any QSK?  k".
I'm sorry I didn't hear you last night and there was no relay offered.
Your code speed is not an issue. I slow down and speed up to try to match the code speed of the current QNI station.
I'm just as happy at 5 wpm as I am at 20 wpm - I don't care as long as I get the calling station in the log.
 
A few thoughts:
 
1. Sucessful QSOs depend on a great number of variables.
    I can't explain why I could easily copy one MO station and couldn't hear another MO station at all.
2. I never heard WB4IEA and W2TAW in QSO. I also have a pixie and know it transmits lower in frequency than what the xtal is
    marked. I had to add about 20pf to one leg of the 7122 xtals to bring the transmitter up to 7123 to get on the Sunrise Net.
   Are you sure you are on frequency? (Just because you can hear a station doesn't mean you will transmit on their listening frequency.)
   400 mw isn't a lot of power but if you're on the Net frequency (usually 7122kHz) hopefully someone will hear you.
3. If you give up you will never QNI the net.  Keep trying.  I'll listen again for you next week.
 
And to everyone - if you hear a station that I can't hear, step up and relay when "Any QSK?  k" is requested. Thank you.

Just got mine finished. I am getting about a watt on a 9 volt. Transmitted signal is clean as heard on my FT817. BUT I am getting a loud hum on receive. I can hear the oscillator of the Cricket at about the same frequency as the transmitted signal. When transmitting on the same frequency from the FT817, I hear nothing on the Cricket on receive. Any quick clues from the group before I dig into the schematic to see where the receive signal is lost?

Hello Wayne,   Make sure you are transmitting "zero beat" with NCS. I am not familiar with your radio, but if you have another receiver, check to see if your signal is very near to the same pitch as NCS. Bill has great ears, but you need to be in his bandpass.   Russ   K3NLT

My QNI occurred about 35 minutes after the net's start.  Had there been an interim QNI call-up, say, after the net's first or second QSO, I would have gotten on the list earlier.

Re: EDZ question

Don Pitchford
 

Lloyd,  I'm a purist.  I always try to make my antenna resonant, if at all possible. A non-resonant antenna often affects radiation pattern more than it affects actual antenna efficiency,  but I like to work without a tuner if I can. Even if it doesn't help signal strength,  there are fewer cables, connectors,  and other pieces to break. I say shorten it to resonance!

I'm returning to the air after a twelve-year hiatus. During that time, my previous antler came down. It was a wildly successful 20M EDZ, 44' each leg, fed with ladder line, up about 45'.

Now, I want to put it up again. The ladder line and center connector are in good shape, but the wire legs aren't, so I'm replacing them.

Here's the question: the calculation for making  a 5/8 wavelength leg is 600/freq. The 44' leg I used previously resonates on around 13.65 Mhz. A leg cut to resonate are the QRP calling frequency would be about 42'8" per leg.

I know that the ATU I'm using (a ZM-2) will eliminate small amounts of non-resonance, but for only QRP use, would the smaller length be slightly better?

Cricket audio hum or buzz no signal reception

Still working on it. Read the description of the circuit and it would help me if the description contained the transistor designation like Q7, Q5 etc..
I get sidetone and transmitted power but a bey high level of buzz or hum in the audio.

I get the same hum in my 80m version, Jess; for that reason, mine just sits on a shelf.  Karl, KO8S

There was a WA8 calling. I tried to relay.

Bayou Jumper?

Hi All,

I am finishing up the build and ready to test drive before buttoning it up.  I am not sure whether I should depress the wings on the sides of the molex pins (crystal socket) so that I can remove the cover (plastic bushings) if I need to and they will slide off.  I am  building (the latest version) rev A(c) (Green board)?  I wonder what others have done?  Thanks.

I don't think the wings will prevent you from taking the plastic parts off. I am pretty sure I have already done it once.
