Radials on the ground aren't resonant. Put down as many as you can fit no matter what the length. 1/8 wavelength long will do just fine. Don't forget, the more you put down, the less lossy the radials will be, which will lower the feed point impedance towards 36 ohms or so.
Go to the ArraySolutions web site for a good article on how to match verticals.
N6LF has written quite a bit about radial systems, both elevated and on the ground.
FWIW, I found using a gasoline engine law edger works great for making shallow slits to push the radial wires into.

Or better, buy  Zeus ZS1 which  has above average TX IMD  and RX specifications unlike the competition.


So I look up Genesis and the board in kit form is $399 which gives me 10mW and the amp which gives me 10W is $249 and shipping is about $50 and a presonus 24 bit sound card with enough inputs to run SSB is $199.  I don't know what it takes to get this running but in the SDR-1000 days which was a sound card radio it took half a day to set up the software with the hardware plus some test equipment like a real dummy load, an accurate power meter, and a signal generator.  I'm running PowerSDR with Flex or this.  How is it I'm saving money?  I can buy a used Flex - 1500 for $500

Digalog CRC-100, has a dipswitch to program the range and offset. probe was a small ferrite loopstick shoved under the tuning section, with a short lead to a 1/8" jack mounted in the rear panel.

I love those shills, the CAI must be salivating over the KAPOS who will parrot the company line!!! 

NOTE  TO CAI:

These folks are the only Amateurs against antennas, the rest of us, would like to see reasonable added to the law.  NOTE REASONABLE.

 

.

You already have reasonable:  Not view-able from outside of the structure.  If it wasn't reasonable, why did you agree to it?


I actually have 80 ft, it has been there more than 2 yrs, Building Restrictions do not apply now (Sorry but in Louisiana CC&Rs are named BUILDING RESTRICTIONS).   Now cry about that.   Liberative Prescription

BAD:  Since I'm somewhat computer literate, I locked on to your post and the word "Funcube."  What can you tell me about it.

TH-F6A - I see that this rig has CW/SSB receive.  Is that receiver only and what is the tuning increments.  I listened to the ISS on my TM-V7A transceiver which has 5KHz tuning increments and found it awkward.

I used to work the birds and had two all-mode transceivers and the rest of it...amps...antennas ..... rotors.  Sold it all one day while suffering a mindfart.

Now I have a hankering to at least listen to them once again..... heard the ISS for the first time recently.  Big thrill.....

If you buy European brands like SMA.Sunnyboy  or Aurora you will have ZERO RFI problems. My whole house runs on solar using  Sunnyboy equipment and I can walk right up to the inverter installation  with my  portable receiver and not hear a peep on any band. Its incredibly good.  You wont be so lucky with the chinese garbage.

My neighbor has an  the Italian Aurora inverters and these inverters are also very good. If I walk right next door to the AUrora I can hear some birdies, however these are so low even if you were running a dipole above the inverter you would not be able to hear them.

There is huge difference between  the European designed inverters and the cheap chinese junk inverters which are unlicensed jamming transmitters they so bad.

If you a ham and wanting to install solar look at the Sunnboy/SMA products you cant go wrong.

Thanks guys.  That's what I figured, but I wanted to hear it from someone else; so strip it is. OH, it is only 4 wires...73

They agree because they are important people and the laws will be changed just for them Smiley
You must understand, these people passed a 35 question test, they are very special indeed.
750000 licensed hobbyists in this country. How many are dead or no longer active in ham radio. subtract the ones who only operate 2m. take away the ones who have no interest in emergency comms. how many hams does that leave to do emergency comms?  and how many of them who say they do emcomms are really setup for it. how many have backup power and are able to relay communications in a true emergency when all power is out?  I am willing to bet that only a small number of hams could actually help in a true emergency.  the only argument you peeps have for HR4969 is the emcomms. but how many of you would be able to participate?  once again I bow to all you important people, may everyone conform to your wants and to hell to those who won't because you are important Smiley

You are not important.  I am a taxpayer, free citizen, nothing more.  I never mentioned emcomm.

Just drop the speed in the Ethernet controller, that can generally get rid of most of the bad birdies. Very  few people need the full speed of their  ethernet interface.

Change the speed to 10mbits half duplex and you can minimize the birdies. You can find this in the adapter settings in "speed and duplex settings"
