Michigan QRP Club Members - Spring Issue of T5W

Just wrapped up the Spring issue of the MI-QRP Club's T5W and sent it to the printers.  Hopefully everyone will receive it before FDIM.

KD1JV's Dual Bander from Hendricks QRP Kits

Installed all the resistors, IC sockets, xtals and diodes today on the dual bander QRP rig from Hendricks QRP Kits today. Will start on cap's and rest tomorrow. The board is a work of art and the install of parts is quite easy...they did a good job on this pcb layout!

Just finished inventorying my DC-40A and Weber's Dual Band QRP rigs from Doug Hendricks QRP Kits. Doing the dual band rig first as it looks the most interesting.

 

My CSM-1 troubleshooting is at a halt for now...can't figure out if it is a cable-wire or switch connection. The problem is not consistent when it comes to touching the affected area. Besides, I need a break and feel like doing a new rig for the summer camping trips.

Prototyping Platforms and Methods

I am finding that it is harder and harder to come up with a concept or scheme where I can make some prototyping surfaces and have on hand to use for experimenting. My solderless breadboards are nice, but sometimes I wonder if stray capacitance, inductance and Lord only knows what else will be present when going that route. Attaching pads to a chunk of old PCB scrap is OK till you you get in a hurry and the glue has not set long enough. I have an islander drill bit and that is fun, but it is a one time use method.

Getting started in QRP

I want to get back into ham radio and I plan to start with QRP. Right now I have no equipment except a $10 analog shortwave superheterodyne receiver, an analog multimeter, and a soldering iron.

Here's my current plan for getting started with QRP. The plan is designed to get me experience in building rigs and to have a useful array of test equipment that will serve me later, as well as keeping costs down.

Super VXO OSC Circuit Variations

I haven't dug into this yet, but would it make any difference if I am using a 2N2222a or 2N4401 transistor for the oscillator circuit for my VXO???

 

Any comments????

Super VXO Sidetracked

I was playing with a Super VXO for 80 meters which worked out - had over 70 KHz swing down to 3.500 KHz which was what I was after. So then started working a 40 meter Super VXO. Got it to swing about 25 KHz which was encouraging. I decided to switch the osc circuit and use the one in the VRX-1 which is where I wanted to use this version of Super VXO. Well, the bandpass filter on my VRX-1 has never performed as well as I expected...so decided to pull the BPF and put in a RF Toolkit BPF from Parts & Kits.

Request information, 6 meter Pixie?

I just discovered this web site and there seem to be knowledgeable Pixie builders here. I was wondering, can the Pixie be modded for 6 meters? I was wanting to try my luck with 6m because I could put up a half-wave dipole, which isn't possible for me on the lower-frequency bands.

These pages seems to indicate it can be modded for 6m:

Pixie - another build

I am a newbie to Amateur radio and although I am almost in my 6th decade on this great earth, I simply feel like a 'kid in the toy store' when I am playing radio. I got my first ticket in March, 2009 and upgraded to General in June. My hope of attaining Extra class status by the end of the year will not be realized, but I should attain that upgrade early in 2010. When I was much younger, I had a desire to try and get a novice license, but that blasted code was the 10 foot wall that I could never scale. Dropping the CW requirement has allowed the hobby to realize a rebirth in my opinion.
