Chuck, I have long thought ARRL Field Day rules need a makeover. The last time I spoke with anyone at the League about it, they weren't interested in new ideas. When digital was RTTY and PSK-31 it see

Jerry, Since you asked, I'll tell you my story. I built a Hilltopper 20, along with a 20 meter end fed half wave antenna, travel paddle, etc to take with me on a trip to Hawaii. For the 9 days I was o

A voice transmitter is required. Usually SSB, although FM will work if allowed. I can't think of any digital mode you can use on a cw only transmitter, other than CW. The good news is your CW receive

Gary, I have several unbuilt 80's, no 80A's. If you are interested please contact me at w9ebk@yahoo.com Don, W9EBK

Tia, QSL. It's working.

I had a home brewed G5RV some years ago. I used a LDG 4:1 balun to match the 450 Ohm ladder-line. It seemed to work as well as any other G5RV I have experienced. Don, W9EBK

Sorry I didn't missed the DMR net, but haven't yet added that mode to the shack. If the 2 meter CW idea gets traction I will suggest it also have AM, and preferably a built in memory keyer (arduino or

John, Allegiant Air flies 2 or 3 flights per week direct to Branson/Springfield, MO from Destin, St. Petersburg, Tampa, Orlando/Sanford, and Daytona airports. Their prices are usually about $75 to $15

Jerry, I have a Hilltopper 20 that is built, aligned, and ready to go. I built it for a trip to Hawaii. If you are interested in the 20 meter version I would sell it for $100, delivered to your mailbo

Rob, Thanks for the link to the article. The good news; it seems very useful. The bad news; it looks like reading your post may cost me $150 and a bunch of time at the workbench. I think I need one of

Richard, Those tiny capacitors are a great reason to buy a multimeter that has a capacitance setting. There are a bunch of them available on Amazon and Banggood for around $30. They may not be lab sta

This message is a bit off subject, but since being employed is helpful to affording radios I hope the moderators will forgive me for posting this. The company I have worked for since 1982 announced th

WA0ITP, OK, you have me stumped! I remember that resistance calculator exactly as you describe it. I recall seeing it in the past 6 months or so. I have done a search of my Gmail account back to 2007

The 30 meter Ramsey receiver I have is basically a Sudden Receiver. I suspect the transceivers were the same RX. I don't know about the transmitters or transmit portion of the transceivers.

A 10 meter dipole is very inductive and high impedance at 6 meters. Although you need to add capacitance to get it to tune, many antenna tumers have too much stray and distributed capacitance to work

Jess, I would start by looking at the output of the audio stage with your scope and see if an identifiable pattern shows up. Then move your hand around the board to see if shielding a certain point on

Lloyd, I'm a purist. I always try to make my antenna resonant, if at all possible. A non-resonant antenna often affects radiation pattern more than it affects actual antenna efficiency, but I like to

Nigel, Each subgroup within groups.io requires you to apply for membership to that subgroup. Membership in 4sqrp groups.io just gets you access to the main group page. There are many subgroups that yo

Roy, Glad to hear your uBitX is working. Mine arrived several days ago, but I haven't yet built it. I guess I should do the audio mod before I even try ro put it on the air. I also have the BitX40. It

I was listening in central Illinois but did not hear anything on 7.122
