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

Re: Hello :) My latest project A NA5N PIPSQUEAK regenerative receiver

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: MicroVert Antenna

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) --------------------------------------------

John, for crickets I always preferred a old Prince Albert’s tin tobacco can. You would be surprised to find how many crickets or sand frogs you could stuff in one of those old flat red cans. I suppose those are collector’s items now(the cans, not the crickets>-)

Re: MicroVert Antenna

More wire has been good for me as well. My radios vary from 5w to about 70w max output. I insisted on having tuned antennas but gradually have deviated and gone to the more is better. Our (xyl is a ham too) latest creation is an 1150 foot horizontal loop fed into a homemade 4:1 current balun into coax back into a manual tuner.
It is at the same time quieter and gives better signal reports than my other antennas mostly dipoles and a 40 m loop. I see (hear) hams who use and brag on air that everyone on 40 needs an amp or they don't belong. huh. Sorry for deviating off topic Pretty hard to be portable except on the deck with a big loop. 73 Dave

Re: Cricket 40?
Gary Kohtala
What about frequency or frequencies for the Cricket 40? It would be nice to have 7122 khz and possibly one of the mainstream watering holes on the low end of the band. Having not yet had the pleasure of building a Cricket for any band, I am unaware of the possible problems related to physically changing frequencies. A standard socket or appropriate female pins on the board would solve the problem, assuming that the crystal has pins and not wires, i.e. solders to the board. In the latter case some sort of switching arrangement would be necessary, increasing the complexity. What have others done and where do they acquire suitable crystals for other frequencies? I won't fully understand the problem until I acquire my first Cricket, which will be right after the first if the year. Thanks for reading.
Best regards,
Gary, K7EK

Re: MicroVert Antenna
N1KWW
Previous wire antenna farm had loop for 160 roughly 560 feet. Competed with those running maximum power. Yes, I was happy. Now everything is scaled down to a 43 foot dipole wrapped around three sides of building. When weather warms up will put up an off center fed with 4-1 balun. (My spell check selected balloon, baling and blain) Building a 20mm QRP rig and placed a semiconductor backwards. Have tried the usual methods, solder sucker and wick to no avail. Any suggestions greatly appreciated.

Re: MicroVert Antenna
Dwayne R
There are two ways to increase your effective power output.
toggle quoted messageShow quoted text
1. enlarge your antenna by lengthening it, or adding elements. 2. Purchasing a linear. Each time you double your power, you have a 3db increase in strength. It takes 6db to make 1 S unit. A linear taking a 100 watt transmittter to 1000 watts is approx 10db of gain 100 to 200 (3db) 200 to 400 (3db) 400 to 800 (3db). 800 to 1000 (round to 1 db). That is a little over a unit and a half of mathematical (not reality) gain. Take a half wave dipole. . .double it, you have approx 3db double that again, you have another 3db, or 1 s unit. Long wires allow more of the magnetic radiation to travel through it. Just like wrapping more wire around a core will increase the magnetic power. I have 600 feet of wire in a loop. It is only 10 feet off the ground, and the lowest point I run into with a riding lawnmower, hanging myself. Someday soon it will be at 35 feet, but until then. . . I use 100 watts of power, and my friends use AL80's and other amps. My signal is almost as good as theirs on 40 meters. You want a station? The antenna is your most important item. If you can't get an antenna that does a good job, then your next alternative is a Amp. QRP means exactly that QRP, not a AMP. . .That means your focus should be, and stay at your antenna. Rubber Ducky antennas and QRP do not work well at all, unless the propagation is strong. It is great to see all these antenna designs. . .small, compact, portable, and amazing in every way. People can brag they talked to people across the ocean, 1000's of miles away. But they either ignore one thing, or are completely oblivious to it. . . You CAN'T talk without propagation! The better the propagation, the easier the hop, the less of an antenna you need, and the less power you need to make a contact. The poorer the propagation, the more power you need, the better antenna you need, and the hop will be far weaker. You are already at a HUGE disadvantage, and that is running low power. So, to compensate for that disadvantage, you can either make it up by a Amp, or Antenna. Since you are not going to use an Amp. . . DON'T SKIP out and build a Rubber Duck Antenna. Fancy and pretty are not good. Effective and reliable is the key to making QRP like any other 100 watt radio out there. Dwayne (Ka0aam) Sorry for the Ramble. . . I just hate to see people get caught up into antennas that are worth about 2 cents, when they have the capabilities to build an antenna for 20 dollars that will out preform these things 10 fold. . . without the complexity. . . --------------------------------------------

Re: MicroVert Antenna
You have lost the mismounted semiconductor. Cut the leads with a flush sidecutter or xacto blade as close to the semiconductor as possible and tip it up or remove it. That should allow you to remove the remaining leads from the thruholes with soldering iron & tweezers or push them out backwards.
Do not overheat and damage the PCB. Good luck.
