4460T Alrightty, makes sense now.. I was thinking maybe it was an Australian-designed kit or something at first. Silly me. The post coming through 4States group should have been a clue that I could ha

Guy: Where is the OZ-17 kit available from? I did a quick Internet search but was not successful finding anything on it. 73 de AK4JA

Happy Birthday! Hope yours is a great one today. 73 de AK4JA

Also, once you've used your Cricket for a while consider using a ceramic resonator (or better yet, two in parallel) along with a 22 uh inductor and variable capacitor in place of the crystal. That wou

Looks great! Excellent work, Mark. Makes me want to build one, too! 73 de AK4JA

Seeing those FT-243 crystals plugged in to the little transceiver reminds me of the ones I ordered from the same company as those two crystals back in the 1990s: CW Crystals Marshfield MO Got some fro

For those of you that may have some trouble manipulating image files, here is the same schematic photo as sent earlier but oriented so that one would not have to use software functions to rotate the i

RE: programmable crystal IC/chip I mentioned earlier about a QST article that used one in a 30 meter Whisper transmitter. (that was the first incidence I remember hearing about them) I have found the

EuGene: Curious here. Did you build one of the GW3UEP 60 meter transmitters? I just finished one and it works great. It puts out around 5 watts output when powered with 12 volts DC. If you did build o

Eugene: Here is a USA source of crystals for two of the 60 meter channels: <https://kc9on.com/product-category/crystals/> This is the location for KC9ON's 3rd Planet Solar site. He has crystals for "c

Just finished a retro rig (6AW8 / 6BQ6 40 meter MOPA transmitter) based on an 15 meter Novice transmitter article in the April 1959 edition of Popular Electronics magazine. It works fine and I've made

Will the IRF510 in the NS40 transmitter by 4States handle 24 volts DC in the final of the transmitter safely? If I add a 12 or 15 volt regulator in series with the 2N7000 oscillator transistor (to kee

Even if you zapped it , you'll get if fixed, no doubt. Hey, I wish I had a nickel for every time I plugged something in backward. You just proved you're human when you did. Welcome to the human league

Might have. I don't see any reverse polarity protection in the schematic online. I hope that there was a diode added in later models that would have prevented a reverse polarity damage situation. Thos
