Even a fresh 9V battery has a high internal impedance. And they droop quickly with a significant load. Using a good power supply, well filtered and regulated would be requisite. Also measure the key-d

Curt, Bryan and All, Attached a drawing comparing two HP filters. One that Bryan suggested and one that was worked up using Elsie. Compare the characteristics. If you can get parts as close as possibl

My fixed-station paddle is a March R-3A; portable paddle is a Vibroplex Code Warrior. Also have a Mini Paddle I often use for testing at the bench. I've had a couple of Vibroplex bugs and still have a

Frank, QRPme.com has kit specifically designed for grinding FT-243 blanks. It was featured as a build-a-thon project at FDIM a couple of years ago. Received good reviews.

Jameco has the machined SIP pins and the price is right. Come is strips of 20 or so. Can't find my catalog for the part number...

Paul, With the various QRPme kits that I have, I use M RCA to F BNC adapters. Or, if mounted in an enclosure with BNC panel jacks, I use a twisted pair of wires from the board to the jacks. The twiste

Wayne, Maybe not all nets and NCSs use QSP the same way. During our 7047 am nets, with weak stations, NCS will ask an operator who has checked in (QNI) and good copy to call, QSP, the weak station for

Terry, Don't know how the propagation is during the evening nets, past my bedtime... :-) But it's been really bad during the daily morning CW nets. Lots of QRN, really deep fast QSB and generally chan

40 meter propagation lately is rather iffy. The 7047 early morning net survives with a lot of QSP between the members and NCS. From me, EM22cv, most of the net stations range from Nova Scotia to South

Phil, There are other board makers who use the ExperssPCB files at less cost. FutureLEC PCB service with comparable quality and FAR Circuits without plated through holes. I've used FutureLEC very good

Now excess to my needs. In good condition and does the job it's supposed to. Asking $50 US shipped to any USPS address. PayPal preferred. Ask me for the address, this email address is not it. This ema

It's not apples and oranges but if you consider how many 1/8 lengths at 146 MHz an antenna 40 meters long would have you might come up with some silly number like that... ;-) Chuck Carpenter, W5USJ EM

My favorite paddle is a March R-3A. Its heavy, doesn't move around with my side-swiper motion and the magnetic action is smooth. Now, if my sending these days were as smooth, things would be just dand

The only "straight key" I've ever had and used is also a WW2 J-38 bought 1955. I used it a lot and even wore a groove in the knob. Not used now and only use the unmentionables... Chuck Carpenter, W5US

Not down here in NE TX but the forecast is for the first frost possibly this week end. Chuck Carpenter, W5USJ EM22cv, Rains Co. TX

My message showed up as did one from Johnny and David. Was at a meeting today with K5DW and he mentioned seeing messages that hadn't showed up in my mail box. Bit bucket gremlins at work again.. ;-) C

Had a nice QSO with Joe, KF0XV, on Channel 5, 5.405 MHz, 1230 z. Still intense QRN but not as strong as the earlier time. Distance about 500 miles. Around 100 mi per Watt... ;-) Using the 88 EDZ for t
