The New England QRP Club invites you to check in to our weekly net, join us at one of our gatherings, build a NEScaf or 79er, work WQ1RP, participate at, or simply enjoy your QRP with our 73.


The NEQRP is fortunate to meet regularly at ARRL headquarters. Our annual meeting alternates between Newington and Boxboro. The meeting generally convenes in the morning (9 am), followed by a lunch in one of the fine restaurants in downtown Newington, with a wrap up using station W1AW. If you would like to bring YOUR QRP rig to the station's antenna farm, tuck it under your arm and haul it in!

About the New England QRP Club

The New England QRP Club is where... "The excitement is building...."

But we love to operate, too. And we enjoy eyeballs, as well.


John Griswold, KK1X, is the Membership Coordinator for the New England QRP Club. If you are interested in joining the club, please email John at kk1x AT with "NEQRP Membership" in the subject line.

NEScaf: A Switched Capacitive Audio Filter

The NEScaf is a switched capacitive audio filter. It is designed to be simple to build and use.

An Accurate Power Meter For QRP Ops

Contributed by Alex Mendelsohn, AI2Q

Have you ever wondered what the real power output of your QRP rig is? How about being able to measure QRPP?

Here's a circuit using two junkbox transistors and a garden variety op-amp that will let you accurately measure your rig's flea power down to milliwatts. It makes use of your ordinary shop multi-meter. If your DMM or analog voltmeter's accuracy is good, your results will be too. It works because power is proportional to the square of the voltage across a resistor, assuming the resistance stays the same.

Although it can't measure a rig's output power while operating into an antenna, it will tell you how much power your QRP rig puts out into 50-ohm resistive loads like a well-matched coaxial feedline. The best thing is that it's accurate!

I posted this yesterday, but haven't seen it,
so here 'tis again:

While your neighbors are warming up their TVs for
the new Fall season, you can check the stability
of their colorburst oscillators, and meet other
weird QRPers at the same time! Yes, you too can
