Think of it as your basic RF propagation and radio wave. . .
toggle quoted messageShow quoted text
The longer the antenna, the more the RF passes through, which gives a better signal. . .any antenna that is very small starts acting like a rubber duck. Way to short of an antenna means a very weak signal on receive as well as transmit. The only way we talk to each other is propagation. In poor propagation, you need a really good antenna to make contact. In excellent propagation, you can communicate 100's of miles by using a dummy load. (I have talked from Wichita to Dallas Texas using a Heahtkit Cantenna). . Small antennas mean poorer receive and poorer transmit. There is a huge reason why the halfwave dipole or inverted vee are such a popular and good antenna. 1. They are very long, and have no "loads/Traps" or "coils" on them. 2. They are cheap and very inexpensive to build. 3. They do not fool the wave into thinking they are longer than what they are. 4. They work well with most propagation scenarios. In other words, I wouldn't waste my time building anything less than a half wave ________ (fill in the blank). Anything less will surely start limiting your capabilities. Then when you run QRP, you are severely limiting your capabilities even . Buy 50 feet of coax, 50 foot of speaker wire, cut 32 feet of length, split it down the center, and attach a wire to each end of the 50 ohm line. If you want, add a few extra feet so you can trim the antenna to the frequency you want. Dwayne (Ka0aam) --------------------------------------------

The Cricket 80a is available eBay with a few other of Daves past kits. He has a presence there with parts too.

Hi John, Yes, the QSB was pretty bad. I usually don't need the entire call to know who it is. I'm just glad you tried. Thanks for your QNI. 73 Bill KV6Z

Hello Tom I previously viewed your radio there , before I ever built this one ! Matter of fact , I saved the pictures from there onto my computer ! Very nice example your radio :) All I can say is mine works much better than I looks :) I have been doing a little experimenting with a coil ! My conclusion so far is The coil built as to the schematic is really hard to beat ! I got to say I do really like this rig ! When I first put voltage to it radio Havana Cuba come booming in with no adjustment at all :) 73 Tom de Frank kd5ald

Re: 40m Net
Bill, The QSB was terrible. Only got 1/3 of your transmissions, faintly heard others but only less than 10%. I'm sure you worked from memory on my call, Hi Hi. I'll keep practicing. John KK4ITX

Surely there's somebody who has made an enclosure for those crickets
out of a bait bucket. Seems a natural (hi).

Gary,

I put my Cricket80 in a metal container that I got at the Dollar store or Dollar Tree. You can still find them now as it is the size a lot of cookies came in over Christmas. It has a hinged (I think) lid. I had hoped I could use a SO239 connector instead of the BNC but there was not enough room for the BNC plug/adapter so I had to wire my SO239 in place of the BNC on the pc board but it works. I also added the key jack mod to the pc board and then drilled my enclosure for that extra hole. Good luck. Jim Pruitt WA7DUY
