Class C? Running FM or CW?

General rule is half the boom length of the highest frequency antenna if it is stacked over a lower frequency antenna. Let's say you have a 10 meter beam with a 24 foot boom, stacked above a 20 meter beam on a 36 foot boom. You would stack the 10 meter yagi 12 feet above the 20 meter yogi.

These look pretty cool. I ordered one that I am going to put on 6 meters. There are a few sites on the web that let you remote control these things. Kits available here, and they are not very expensive: Five Dash Inc. Your Source for SoftRock Radio Kits Anyone here got one of these?

Almost sounds like it was "inhibited". Smartnet/Smartzone radios can be, not sure about Mototrbo. If radio was stolen, radio system manager can send out an "inhibit" signal, which turns radio into a brick. Can only be uninhibited from system that inhibited it. Or replace controller board.

Wow, I am surprised at how good the F/B is on that. Foward gain not too shabby either. When are they going to be available? A 17 meter Moxon, might be a hot seller, as well.

Looks nice! That would be a really great antenna for a beacon station, or nice antenna for monitoring band openings. What does the pattern look like, and what is the price? I want one!:thumbup1: On edit, a center frequency of 50.150 would be useful, as most 6 meter SSB/CW ops monitor the lower...

I think I bought one of those at a garage sale for $10. It did not even have a tank circuit. I think the tube was coupled to the coax connector through a blocking capacitor and a small coil. Took out all the phones in the house, when I tried to use it on 10m FM.

Been playing with this problem a little bit more: Disconnecting 40 through 10 meters off the band switch has no effect on the problem. Removed the 10/15 portion of the tank coil, it's 7 turns of copper tubing. Been trying various combinations of coils to replace it. Finally got a 35...

Agree with the Captain on this one. :thumbup1: When I worked at a Motorola shop about 10 years ago, we had done some experiments with 1/4 wave versus 5/8 wave. Found no difference at all. No S-Meters on commercial two way equipment, just your ears. And the ears heard no difference.

Got a pleasant surprise this weekend. Found out my 80 meter inverted V loads up on 12 meters, quite well. Worked quite a few Europeans on 12, with 100 watts and 80 inverted V at 55':)

Played around with various things this past weekend. Got out the grid dip meter and everything dips higher in frequency than it should, by quite a bit. It's starting to look like something is funky with the 80 through 20 coil. Nothing visual that I can see, but it's tough to really look at it...

Check the 500 PF and it is being switched in on 80 with ohm meter. Plate tune is between 10-15 mtrs on the dial and Load control is around 9. On 40 both caps are at maximum mesh. Almost acts like it has not enough coil on 40 and too much on 80. Weird.

I have directly grounded all the grids. Input circuit is fine, low swr. Plate tuning is in the 10 m slot on the dial and loading is around 9. This makes both the capacitors barely meshed. I get a nice dip on the GDO on the second harmonic. Around 7.5 Mhz, when bandswitch is in 80 M position.

My amp has about 70% reflected power on 80M. When just running Kenwood tranceiver, 2%. That can only mean one thing. The darn amp is putting out harmonics "somewhere". A check with a grid dip meter shows the tank circuit is resonant on the 2nd harmonic, more so than on the intended 80M...

A wise man once said, "It is better to seek forgiveness, than to ask for permission."

#6 Solid Copper, minimum. Just kidding! Probably what ever you can afford. The cheapest route would probably be galvanized steel electric fence wire. You can buy rolls of this relatively cheap at Tractor Supply, or any farm supply store. DX Engineering has radial kits and biodegradable...

It seems like the majority of the folks that have them, seem to have very raspy sounding transmit audio. Has anyone else noticed this? Also, not overly fond of the LCD display. This is making me lean more towards the Kenwood 590.

The Hustler 5BTV is an excellent antenna. Being a vertical, it does need radials. DX Engineering has a good deal on them and some good hints and kinks on how to get maximum performance out of one. I hear a lot of mobiles on 40 meter SSB, with great signals using screwdriver type antennas. I...

Joe Walsh, met in person. And Jim Bonfante, drummer from the Rasberries. Don't recall his call as he upgraded to Extra and changed it. Also talked to the space shuttle on 2 meters. I think I have the cassette tape of that QSO somewhere. On edit: I did meet Ronnie Milsap at the AES store in...

There is an expensive Larcan on Fleabay now. I think the guy is asking $1299 for it. Yikes!:unsure: Now that I have gotten my antenna system the way I want it, now on to the amplifiers!!
