My Ham Radio Home Page

(You may have been directed here from You’ve landed on my ham radio home page. I’m KEØOG, an Extra-Class ham radio operator. I’m active on HF, 2-meters, and 440 MHz. I use this page as an index to ham-radio-related material on this site.

What is ham radio? Watch this video from the Radio Society of Great Britain (RSGB)

Current Geomagnetic Conditions for HF Bands

This chart shows various geomagnetic indicies and what the sun looks like now. These indicies show what HF propagation is like right now. You can use data like this to help you find a good HF band for operations. You can refresh this page to get the latest data.

    Dave, I just used your information and that from W4EEY to pass my General. I held a Technical Plus (or at least that’s what it used to be called indicating I passed a 5 wpm code copying test) for many years but wasn’t very active on 2m. Actually I do mostly SWLing.

    I am on fixed income, so my funds are not infinite and I am careful as to where I spend it. I have found your information to be more than worth my time in helping me in my “ham path”.

    Mr. Casler,

    I just wanted to drop you a quick line and tell you thanks for your many wonderful, informative and educational videos you have posted on YouTube. They have been a great help to me not only in rekindling a long held interest in this hobby but also for the education I’ve received through the Technician and General class license course series. Today I sat for my exam and not only passed element 2 but went on to pass element 3 in one sitting! As I only have just passed the exams today, I have no received my call sign from the FCC yet but I am looking forward to that as well as the Baofeng UV-5Rx3 that I ordered this afternoon. I’m already looking forward to diving into the HF bands soon but I have a little more research to do before that jump (as well as another paycheck or two). I also joined the Lewisville Amateur Radio Association ( and I’ve already met many wonderful people and gotten a ton of great getting started help there.

    Thank you again for all you do for this hobby and hope to see you on the air soon.

    David, good luck with your studies. The choice of a handheld is a highly personal decision. See what your local club members are using–if you get something like that, you’ll have others around you to help you with the rig. 73, Dave

    Hi Dave,

    Working my way towards Technician Test next month – Using your videos and the ARRL Manual to study. Do you have any new recommendations for a starter HT radio? The TYT UV 8000E you reviewed looked good. Is it FCC certified? The 8000D seems to be . . .

    Is there something newer, better that I am missing? There is so much out there. DMR, GPS, etc.

    My first ever “73” is offered to you, David

    Kenny, you might be safer to transmit into a dummy load, then have a short antenna on the radio under test. I don’t trust attenuators unless they’re lab grade with lab grade cables and everything perfectly grounded. Not much signal needs to find its way around the attenuator to completely overload the receiver. Hope that helps. 73, Dave

  6. Kenneth Lung says:

    Hi Dave……I can’t afford to purchase a real comm tester unit, way too expensive for my budget. I need a way to generate microvolts for testing radios. I was wondering if using a HF radio (power output 1 watt or so) fed into a variable attenuator (adjustable 0 – 82 dB) and then fed into malfunctioning radio, might work? Would this be safe and also generate the microvolts needed for testing? As long as I can get an acceptable input level, I suppose it doesn’t need to be exact. I just need to be able to trace the signal through the radio. Any other suggestions for doing same would be greatly appreciated, too!!

    What you are seeing is the factory calibration mode. Contact using the email address on the page and ask what to do to get it out of calibrate mode.

  8. Gary North says:

    Hi Dave I saw ur video about the bitx40. I’m wondering if u can help me. I put mine together and the display say calibrate when turned on, any ideas what’s causing it.

  9. dcasler says:

    Try one of your suggestions and see how it works. When you have multiple factors present that can affect antenna performance, often your best bet is simply to try things.

    How are you, Dave? ANOTHER Q for ASK DAVE..

    So. our house has a metal roof. on which a short (~1.5 m ) TV-mast is mounted (sans antenna) at its peak, at about the roof’s center; there is also a chimney (not yet used).

    My (still flexible) plan is to:

    1. mount a (6 m – 23 cm) discone atop that mast… &

    2. find ways to ways to use it to also support 1 end of an HF wire antenna, eg:

    – a Sloper: HF wire would extend over the backyard, eg, down to 3-conduits, duct-taped together – over their entire length (= 4 m) to form a “DIY vertical support,” secured to a well-planted metal fence-post, w/ guying to keep it from bending / falling L or R, in wind..

    BTW, I could replace the 3x conduits with 3x larger-dia. 6 m drainage pipes (also PVC) & similarly duct-taped ’em together, to get the back end up 2 m more than the conduits would.

    Alternatively: A shorter Inverted-V with its center atop that mast: 1 leg to a tree in front yard; the other to a metal shade-cloth frame, between back of house & back yard.

    What would you do, in a similar situation? Any other comments welcome.

    Thanks, Dave & 73

    Dave I want to thank you for all of your efforts in advancing the hobby for newcomers like me. I was able to successfully complete all three of my tests, in one testing session, thanks in great part to your training videos. I combined them with and the ARRL manuals and pass. I have also learned a great deal from your “ask Dave” series. Please keep up the great work and thank you!

    Hi Dave!
    I used your videos a couple of years ago to study for my technician and general class license. Thanks for everything that you put into those! I know for sure when I decide to work on my extra, I’ll be back for more of your videos!

    I remembered you are a motorcyclist as well. I saw your video going over Engineer’s Pass.
    I am back on two wheels myself finally after 10 years of not riding. This time I’ve found myself on a Vstrom 650, and have quickly learned that I want to do more of this adventure riding thing. What better way to combine so many hobbies all into one?! Riding, camping, hiking/exploring, and now I’m adding radio on top of it all. I’m wanting to do things like SOTA, APRS, Winlink, and maybe even limited voice contacts through my Bluetooth helmet system too.
    Have you done any motorcycle mobile installs, and/or made videos about it?

    Right now I only have my new Kenwood TH-D74 to experiment with, but I plan on building a com box for the bike with my TM-D710, and eventually a 857d for HF too. Though the HF won’t be a bike mounted antenna, just along for the ride and used as a portable field set up at campsites and the like.

    Thanks again!
