Chuck, The one I currently use is a Vividia USB Borescope. It's listed as $76.22 on Amazon. Don, W9EBK

Jason, I highly recommend a digital microscope. I rank mine up there with my soldering iron and my multimeter as "must have " on the work bench. I recommend getting one with a good base, and rack and

Curt, I'm finding 10 and 12 meters weak as well. Given the SSN and SFI I keep expecting 10 and 12 to really open up, but keep meeting with disappointment. 15 and 17 are usually good. 20 meters is Grea

Larry, My first guess is the counterpoise wire is too long. Based on your description it sounds like you built an Off-center Fed Dipole for 4.875 MHz. Try shortening your counterpoise to 3 feet and ch

David, Thanks. No need to send the tracking number. Don, W9EBK

David, Thank you for the donation. Our radio club really appreciates the generosity. I have had at least 3 80 meter transmitters donated. Another ham donated 10 of the specialized direction finding re

John, Yes, I'm good in QRZ. I would be happy to send you something to at least cover shipping. I have a few spare parts from one my XYL built and had very low power out. I should be able to get the in

I have a request for anyone with an 80 meter cricket and no plans to use it. Our local radio club, svrc.org is gathering equipment for some on-foot ARDF style transmitter hunts. We're looking for buil

Doc, N9PUZ's advice is very good. I will add these things based on personal experience. Bringing the wire all the way in to the radio will work well for receiving. The problem comes with transmitting.

Some members of ARRL's Amateur Radio Direction Finding committee have been working with an original 4SQRP 80 meter cricket as a possible transmitter to use in 80 meter direction finding applications.

Ron, Thanks for fixing the link so quickly. Jerry, WB8WFK said he was able to get the instructions as soon as you fixed the link. He has the 80 meter Cricket built, tested, and has already worked out

I gave one of my un-built 80 meter Original Cricket transceivers kits to another ham. He reported the instructions on the 4SQRP website are for the newer version; the one that uses a keying transistor

I'm at work so I don't have time to look at the schematic but from the description it sounds like the current limiting resistance on the Red L.E.D, or the cutoff current of that L.E.D, is too low. L.E

Doc, I've grown to really like end fed dipoles. They are a bit expensive, but they seem to always work well. Don, W9EBK

NDB is a non-directional beacon, used for aircraft navigation. They were largely replaced by VORs in the 1960s and later mostly superceded by GPS. Nevertheless some NDBs are still operational. Our 197

John, I like your idea of a hybrid, but here's my twist. I remember an article in a ham magazine many decades ago about removing the tube finals and running just the driver to the output to make a QPR

If you would like to get involved in designing and building some 80 meter CW transmitters, I have an interesting project. I’ve been involved in Amateur Radio Direction Finding (ARDF) for many years. A

I know this isn't the group's focus but, I received an inquiry from someone wanting to take the Technician exam in the St. Louis area in the very near future. I haven't found any listing for V. E. ses

Dave, There are too many variables here for me to make a suggestion with much confidence. I don't know what model VNA you are using but if it's a $50 mini-VNA it might be that the numbers you are gett

Paul If are comfortable taking the rotor apart to service it, you can buy a retrofit kit to change old Ham series rotors to the new single connector style. Hy-gain/CDE is now owned by MFJ. I didn't fi
