Hi Curt,

Sounds like you got it fixed, Great! I don't know if anything got salvaged from the Ozark Patrol group on Yahoo (I couldn't get anything there) so I am wondering if maybe a separate thread should be started for Mods on this receiver. I think this receiver has good potential for a QRP station, suitably matched with a transmitter. I had no luck further fixing my problem of controllable regeneration on 40 meters, but I will start playing around more with it. Since I got it right on 75 and 80 meters, I think I will eventually stumble on more stable regeneration control on 40 meters (as I previously posted about.)

73s, Jerry Wysocki, KC9JXE

Excellent David,

Thanks for the suggestion and all your help on this matter.

Hello David,

Just a thought.  I had the 80 meter cricket a few years ago.  Just reviewed the 80 meter schematic and see that the 80m version had a 1K ohm resistor for R1
The 40m schematic shows 470 Ohms for R1, So, I think, you are correct placing a 10K or even a 4.7K resistor in place of the lower value (470) R1.

I decided to experiment a little after seeing your post. I first tried replacing the coil L4 with varying resistor sizes, I had quiet receive, but no or very little power output. I ended up replacing L4 with a coil that I wound - but had marginal improvement. I then suspected that the crystal oscillator is probably overdriven, so I placed a 10k potentiometer in series with R1, adjusted it until the hum dropped off and it seems to be fine now, RX sigs are much clearer, even with the pot maxed at 10k - I'll probably just pull R1 and place a 10k in its place, - TX is still .7 W. I hope this helps. 73 ab9bz

Hi Jerry. I built my 30m Cricket several months ago and had the same problem. After carefully inspecting it several times I couldn't find where I messed up, so I put it aside and haven't touched it since. Hopefully, someone here will have a suggestion or two so we can both put this neat little radio on the air.

I built a Cricket 30 kit some time ago and just put it on the air. When I turn it on it sounds ok for about one second and then hums very loudly and does not change. It has full power output. Any ideas?

A 10-50 pF trimmer did the trick.  Now pretty close to 5-12Mhz on the upper band.  Lost 20M, but still have 40 n 30.  Thanks,

Curt KB5JO


Re: Ozark Patrol Tuning adjustment question

Curt
 

Ok, since the 560 pF cap isn't in the circuit for the 5-12 MHz scale, assumes this means need to add some capacitance in parallel with the capacitor to bring the top frequency down.  QSL the trimmer, but I thought that was what the trimmers on the back of the variable capacitor were for, to adjust the tracking of the tuning.  Adjusting these makes no difference for me. 

For the 1.6 uH tank, the maximum frequency now is about 15.5 MHz which implies a capacitance of 70pF.  At 12 MHz implied capacitance is 110pF.  So, I assume putting a 40 pF cap in parallel with the tank will get the tuning to track the dial markings?  I think I have a 50 pF trimmer and will give that a try.

Thanks,

Curt KB5JO

GM all.
I checked in this morning with the local gang on 3720...
I got 20 over reports from Syracuse and Rochester.. and a solid S9 from Ontario and MA.   I'm located between Roch and Syr. 
in central NY.
The audio was great.. I'm never surprised how 5w performs.

Re: Ozark Patrol Tuning adjustment question

Tom Denton
 

Back to the original question. When I asked Russ Ramirez this same question he replied:

Typically to get a dial on a receiver, signal generator, etc. you have an adjustable coil for the low-end of the band in question and a variable cap for the high end. In this case, the inductance is fixed and yes, the 560 pf capacitor can probably be increased a little to bring things in line. A 680 pf cap may not be excessive, but if it is, then another cap in parallel will be additive. If you happen to have a small trimmer cap to solder in parallel, that would be a good way to dial things in.

I posted this earlier but cutoff Russ' reply.

KD4MSR, Scott
 

Fellow CW-nauts:  I put up a new 132 ft MFJ Half-wave as an inverted vee with the apex at 60+ ft, broadside to the NW (facing Missouri), used my full 100W (big stuff for a QRP guy), my first time on the 4SQRP 40 mtr net last night:  At my QTH just outside the Atlanta perimeter, S 7 to S 9 noise including QRM, QRN, plus QSB.  The Latin America sideband guys were in there, too.  Using headphones, CW filter, and some DSP, I heard/worked WA9PWP Paul in WI; KK4ITX; WQ8S in MI?.  KK4ITX was strong, then nothing.  On 80 mtrs, nothing.  Charlie Brown would say, “rats!”  Just before 40 mtr net I worked K9YA Club station in Skokie, IL.  TNX ES 73/72 DE KD4MSR, "Professor L. O. Power,” Scott  (BTW, my long-planned late May Katy Trail bicycle trip across MO looks to be cancelled.)

Paul,

I was probably the other “4” in the noise, almost had two K4DMSR and another I cannot remember.  Between the QRM (I get some Latin America stations on LSB on 7122 often) and the QSB it was not in the cards.

Made some noise anyway.

w2sh@...
 

Guess I and a couple of others should have checked our e-mail in-boxes before going QRV.  I had lightning, thunder and high winds yesterday and was entirely disconnected and grounded.  Today was gud wx so I tuned up on 40m. Did a couple of "4s?" and raised WA9PWP at 589.  Stood by and then heard KD4MSR at 579.  Paul and Scott had a short exchange and then we three waited in the wings, but nothing happened.

Went next to 80m.  Heard WNØWNY on 3,564 kHz at 559 but nothing else.

CU guys later.

72,

Charles (aka Chas), W2SH
