Wayne, The Thursday morning net went dark almost a year ago. I miss it and wish someone would step up to call that net. I would volunteer, however, in my present condx of recovery from an operation

Here is a link to the author's article that did the write up on the resonant speaker for QST. I found it on Google. Very simple and easy to build. 72 Johnny AC0BQ

Gary: I believe I was one, I received the two washer that fit under the Morse key but only had one smaller aluminum spacer in my kit. So if you could mail me one or advise that would be great. Are the

Hi Gang, I went to Home Depot and picked up some Poplar trim wood they have in 4" X 1/4" X 2' pieces and used that to frame up the inside of the box a bit. The one I saw in Branson had the Cricket

Hello, Where can I find a " hopefully virgin " cuspidor/spittoon at? It adds class to the appearance of the housing of this speaker. Sam Neal N5AF Celebrating 60 Years In Amateur

I made a pair of these Dixie Cup resonant speakers today. Remarkably, they have a very sharp peak at 600 Hz (my preferred center frequency). I opened up the filter on the KX3 and found that the

I don't have a cricket yet (its on order). I put together the oscillator on a test board here to try out some crystals I had. To simulate the load of the final, I used a 10K resistor to ground. I

Good morning all, May I please remind all that the QRPSpots page(www.qrpspots.com/) is there to be used. It is a super tool for announcing your presence on a specific frequency/band, right now I'm

Good morning Jeff, Terry - WA0ITP - used to call the Thursday AM net on 40m but I believe it's been inactive for a while. Maybe someone else knows something? Blessings, Wayne - NQ0RP -- QRP -

I would have to concur with the last few posts. C10 seems to light to me. I used up to 470pF for C10 (and 270pF for 40M) and even lowered R2 down to a 330 ohm 1/2W resistor when playing with an SVXO

Yesterday morning at 8 Central I dialed around 7.122 listening for Morning Net activity... and heard nobody. (After scrambling in the rain, umbrella in hand, to connect my feed line, it was a

Looking at the circuit – the oscillator is not loaded too heavily by the PA (it ‘sees’ a high impedance at the input of the PA), so no changes there. One simple thing to try is to pull the

I don't have a Cricket, but I would think by changing the values of C9 and C10 you could get these Ebay crystals to work nicely. Maybe try raising C10 to 220pf and reducing C9. Maybe put a variable

Ouchie..... Anxiously waiting the verdict on the HC49 crystals. I had been planning on putting in 3535 at the minimum, and perhaps 3550, 3560, and 3579. I had been wondering if there might be a

Don't feel bad, I have that issue with my 3.579 crystal. Takes several tries of hooking the battery up to get the circuit to oscillate. -- Tom Sevart N2UHC St. Paul, KS

I have the same behavior with my 3560 crystal. Sometimes it works, sometimes not. I ordered some from the auction site, hope wasn't a waste of time. Still trying for first QSO... 72, Curt KB5JO

I'm finally about to finish my test set after having it stored away in a box for many years. I'll post pics when I'm done. -- Tom Sevart N2UHC St. Paul, KS

Ouch. Not good news but hopefully someone will find a cure. Ah, well. Switching to 3560 is a good idea - we just have some implementation problems. Thanks for your work. Bob, WA2CKY

I ordered a 10 pack of 3560 crystals (HC/49 style) from 3rd Planet Solar on eBay. Got them yesterday and finally had a chance to check them out. NONE will oscillate in the Cricket. The crystals
