(You may have been directed here from www.ke0og.net) 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.

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.

Becoming a ham radio operator
- The three amateur (ham) radio license classes. Some background material on license grades, the difficulty of the test, and the operating privileges.
- Videos to aid your self study for your ham radio Technician Class license: Technician Class Ham License – On-Line Help for Your Self Study, which you can also access directly from
www.ke0og.net/training. The purpose of this series of videos is to talk you through the self study you’ll be doing with the ARRL Ham Radio License Manual. There’s one video for each section of the book, on the theory that it’s easier to study if someone’s given you a little overview. - A similar set of videos for General Class
- A similar set of videos for Amateur Extra Class
- Randy Cassingham’s intro to ham radio
- How much does it cost to become a Technician Class (entry level) ham?
- How much does it cost to upgrade to General or Extra Class and get on HF radio?

I’m not familiar with the Ringo antenna. I’ve seen them but haven’t studied them. I can’t say if they’re electrically equivalent but I think probably not.
Hi Dave
N1URE here. Question on an antenna design. Is a Ringo style antenna electrically the same,as a j-pole? Thanks for your thoughts. Larry
I have been working with a journeyman electrician to put in the underground transmission line, the grounding electrodes or ground rods and the wire connections for bonding.
I am using 2 inch PVC conduits with right angle bends of steel conduit to avoid cutting holes in the conduit at the bends when using string or rope- the steel conduit is not cut like the PVC, so less chance of getting water and soil into the conduit.
Some had suggested drilling holes in the PVC conduit and placing the conduit over gravel to drain water from the conduit. Doing this would allow soil and water to enter the conduit and plug it. The conduit is there to easily replace the transmission line without digging another trench.
When bonding, you said cad weld was not the best method for making connections. Why is this, and what do you suggest?
Hi Dave,
I could not get the normal Ask Dave page to work so hope you see this here.
I just bought an Hy Gain AV 640 and I was wording if I can tune it while it is still on the saw horses. going to be a pain to get up and then have to take it dow again to tune.
Thanks for all you great advice. Look forward to the live streams on Thursday and Saturdays.
All the best,
Jeff Wittern KE0KRO
Can you speak to our club
Papasys.net
Please call me to work out details
thank you in advance for considering us

Yes, likely it will work file if it’s about 36 inches in radius or so. A smaller plate should also work.
Dave, brought a piece of brite stainless steel to use for a ground plane and a mag mount ant.
I find the magnet dosnt stick to this steel well, and only a slight improvement in match. Can this non magnetic plate still act as a ground plane?
I have the same antenna turner . Sometimes when I tune my antenna, the antenna knob well be on 3 ( for instance) and the transmitter knob well be on 5 or 6 why is that? should the antenna ,and transmitter knob be on the same number ??

Dear Dave,
I am studying for the General License and appreciate your videos.
I want to study and experiment with auto patch and phone patch. Please let me know if there are any sources of information, links, etc. I want to learn how it works and what is required.
Must this be done by repeater?
How can I use a satellite for this function?
As I often live in an RV outside normal telephone service, I want to learn about this for safety and security. Meaning very occasional use.
I also would like to use satellite or any means to use internet by ham radio. Please recommend a resource of information if you know any.
Thanks for any help.
Paul C. KF0AJH
P.S. I am now in CO, where might I connect with you by radio?
Hi Dave,
I sure enjoy your amateur radio YouTube video series.
By way of furthering the art, I offer a cautionary note regarding the IC-7300, and damage possible from mis-steps involving use of the PTRX-7300. You may want to look at this interesting FB posting and its comments section, where the poster explains How his radio was damaged:

I know you have answered this in the past but I did not pay attention because there was no need for me at the time. Things have changed. What cameras and microphone do you use for your live streams. I really enjoy them and have learned a lot. Good luck with your flying.
ke0og.net/ask-dave is a web address not an email address. Click here: http://www.ke0og.net/ask-dave and fill out the form.
Dave I have tried to send an email to you but I keep getting put in a proper address I have put I ke0og.net/ask-dave and it doesn’t work
Hi Dave, I was wondering if maybe you knew the answer to this and would tell me. I’ve got Windows 10 and a Boufang v9. Ive also got an Icom Ic 7300. Ive got to download a usb port driver for my Icom to work with my PC. Your video for Chirp and Boafeng states I need a driver downloaded with a red cable I already have. Will my Icom driver work.
Thanks for you time. I’m “Jon” KD4LPH 73’S
Hi Dave,
Two quick things-
1) Thank You for your great YouTube videos- you have an amazing gift for teaching.
2) An anecdote: You give a shout-out reference in video #110, Antenna Modeling, about Ward Silver’s “Antenna Modelling for Beginners” book, and opine that it’s expensive at $34 but worth it. If you still have your copy, lock it up! I tried to order one tonight (based on your always reliable recommendation:-) and found the book’s out of print at ARRL. Used copies on Amazon & eBay are going for $85 to $130 now. You’ve got your hands on a rare classic asset:-)
Cheers & 73

HI Dave. My call is G4LD -licenced in 1981 in Dartmouth, South Devon,England in 1981. At that time I operated HF SSB/CW using a pair of Trio 599 Custom(M) specials. I also had a Yaesu FT290R working the RS Series of Satellites. I went QRT in 1986 for a private reason but returned to the hobby in 2017. Trying to catch up with technology has been a real task. I now operate HF, VHF and UHF – Yaesu Ft450D and a Yaesu FT991A. I use a OCFD Windom 80 through 6m and with a 4 element beam in a fixed position about 20 feet above ground. I have discovered your Ask Dave U-Tube series and I find them interesting and helpful particularly as you are a very good presenter with a great reasonant voice. This note is just to say hello
Good morning Dave,
I hope things are well. I just got my Tech License a month ago, before everything got locked down. I am really enjoying talking with the local Hams around my area when I am at work. However, I live a little too far away to reach the repeater from inside my garage. I would like to try a make a J-pole antenna, to help my handle reach the repeaters. I have seen people make the j-pole out of the 300 Ohm Twin lead, can I make j-pole from 12 gage household electric wire or 16 gage low voltage wire? I have more than enough of both to make one in my garage, or does it need to be Twin lead?
Thanks,
Joseph KO4CWF
Good morning/afternoon, I have a question I got technition license some years ago in California but recently have moved to Florida. And am considering getting back into to ham radio and get my general so my question in your opinion which band would you say is the most reliable coast to coast??.. Dave Yates KJ6JVW 73
