Dave and all, True you cannot use a USPS Priority Mail box to mail by any other means than Priority Mail. The boxes are free of charge to you and can only be used for priority mail shipments. You can

Wayne and all, You must certify that there are no hazardous materials in the parcel. That can be done at the post office retail counter or on-line if you print your postage sticker at USPS.com. This h

Elecraft may have the 2 band boards still available, check with them to find out. The K1 may have been discontinued, but the options will still be available until the supply runs out. 73, Don W3FPR

I guess I live a charmed life with a good and conscientious USPS delivery person. I get a LOT of USPS packages, and for those that do not fit in my large mailbox (at the end of a 3/4 mile unpaved priv

Ed, If you want to obtain a panadapter display from the KX3 RX IQ output of the KX3, get a soundcard that is capable of at least 96K bandwidth, 192k is better. Yes, the input must be stereo for RX IQ

Bry, I must strongly disagree. An RF Ground must have a low impedance at all frequencies in the RF spectrum. Consider my example of an 8 foot wire (or braid or whatever conductor) to a ground rod. Yes

There is no way that a ground rod will create an RF Ground for your station. The earth is not a 'sink' for RF energy. The ground for your station is for AC safety and lightning protection only. Your s

All, I listen to the group chatter, and I get lost most of the time. That is because I download the posts as email, and more often than not, posts have no reference to what you are replying to, they a

Marty, Take a 40 meter board and convert the tuned circuits to 80 meters. A bit of calculation for the Low Pass Filter will be in order, but it should be quite do-able. Look at the Elecraft K1 2 band

You might want to support another ham and order the ferrites from Howie WA4 PSC. He is the owner of Pro Audio Engineering. He has clamp-on ferrites at reasonable cost. See https://proaudioeng.com/fair

Nate, Get a female associate to look at the color bands. Generally their color perception is much better than for us males. My XYL claims that my box of crayons is limited to 8 colors while hers has a

Making an adapter for HC46/U crystals to the FT-234 socket is not difficult -- If you have an old octal tube, break the base but save the pins - they fit into the crystal socket holes. Get a strip of

I can appreciate your efforts to re-create some of the gear that we worked with "way back when". However as a old-timer, I have done that a long time ago when I was learning what this hobby is all abo

Oh yes, I remember those days of cathode keyed transmitters. If you contacted metal parts of the key, you could get quite a shock. Some actually keyed the B+ instead of the cathodes and the key became

I know it will modify the "Paraset" appearance, but if you cannot obtain real FT-243 crystal sockets, know that the crystals will fit into alternate pins of an octal tube socket. We used to do that in

Roy, I suggest that you and anyone else looking for a good and versatile keyer chip (or a keyer kit) that you take a good look at the K1EL keyers. The K-16 is their more recent IC and for $8 it cannot

Paul, See if you can find a copy of Experimental Methods In RF Design by W7ZOI. It has a lot of design information. It is an ARRL publication, but is currently out of print. The ARRL Handbook also has

Dave, I may be proven wrong, but I don't think filters on two different frequencies will give the same effect. SDR receivers are based on the 90 degrees out of phase signals derived from a quadrature

Tim, I have bought stainless steel hose clamps from Home Depot, Lowes, hardware stores, and automotive supply places. Look around locally. Some do not have SS adjustment screws, but many have SS bands

Jim, They are used normally for adjusting trimmer capacitors. The rotor of the trimmer is connected to the adjustment screw, and if that side of the capacitor is not connected to ground, you will not
