4SQRP Kits


4SQRP MagicBox - Not finished yet


MagicBox finished front side.


MagicBox finished back side.


New SS-30 Reciever kit to build. Taking parts inventory here.


VXO


VXO setup for FT-243 type crystals. This configuration bends the crystal about 2kc.


VXO setup for HC-49 type crystals. This configuration bends the crystal about 6kc.
Testing a 7.114 crystal now covers 7.111.00 to 7.116.92mHz.


ATS-3b


ATS-3b during the build. Pretty small stuff.


ATS3b inside the Altoids tin.


ATS3b finished with label in an Altoids Tin


ATS3b with filter box and rotary encoder. I attach the encoder with a small ribbon wire.
I chrome plated the altoids tin for the encoder. Nice fingerprints.


ATS-3b more mods. Now adding a W5USJ audio amplifier, speaker and volume control knob inside the rotary encoder tin.


ATS-3b with a W5USJ audio amplifier, speaker and volume control knob inside the rotary encoder tin.
Works great with or without the headphones now. Tiny speaker came from a laptop.


RockMite


RockMite 20m in a Sindy Altoids Tin. I have the matching tin called Cindy, it's the same without the horns.


Inside the RockMite 20m. I ended up giving this to a friend.


Super Tuna Tin


QRPme Super Tuna Tin with 20 and 40m modules - Bought for me by a friend.


Another shot of the finished super tuna tin.


NESCAF


NESCAF circuit is built and aligning for the holes that need to be drilled in the tin.


Holes drilled and ready for wiring up the controls.


All wired up and ready to smoke test it. No problems, worked the first time.


Finished in an altoids tin that I chrome plated. My first try at chrome plating at home.
Not that great with the scratches, but it was fun and a good thing to learn on.


Here is another NESCAF filter in progress.


I helped a good friend finish this one and put it in the enclosure for him.


QRP to go box


My go box ready to take to the field. Contains my ATS3b, ZM-2 tuner and my K2RFP mini key.


MightyMite Homebrew


This was a fun home brew project that I found in an old magazine called Michigan Mighty Mite.
I called mine the Florida Mighty Mite. It isn't very mighty though.

AM MW Transmitter


I built this AM MW transmitter using a LM386 and a 1mhz crystal oscillator.
The MP3 player is pretty cool, lets me use an 8gb USB memory stick loaded with stuff.
Works great for listening to old time radio shows on old tube sets or even my crystal sets!
