Where's Dionne Warwick?

I hate to disagree with anyone who has a kilowatt but this is plain incorrect. Some military and marine rigs use one sideband with carrier. Almost all riceboxes use double sideband in the AM mode. There are only a few exceptions. The AM produced by a properly setup ricebox is AM just like an...

4 ARE easier than 3 without a hub. Get a telescoping tower. You only go around once.

13-1/2. I've seen your charts. That's a lot of good scientific work. Thanks for sharing.

The price of admission. http://www.worldwidedx.com/home-brew-mods/41252-failed-experiments.html#post173073

This probably makes a better new thread than tacking on to the old one. I've detailed a few of my antenna exploits here in the past. The search feature might find some of them. One I never mentioned was the 6 element yagi I built using radio Shack mast for a boom. Junk elements were from...

No reason not to use 5/8 wl radial(s) as long as there's range in the matching network. I had one up with one radial pulled off to one side of the tower a few years back. It's detailed on this site somewhere if anyone cares.

Yup. Racks full of expensive custom bandpass filters rendered useless. $$$$$$$

Good stuff but a J pole is a waste of material on CB. The first 1/4 wave of metal is just a match which doesn't radiate much. OK on 2 meters though.

In this case 4 are easier to implement than 3. Like I said, I wouldn't listen to me either. Been there with the radials myself. I even tried connecting the ends about 34 years ago.

http://www.cbtricks.com/radios/lafayette/comstat_25/graphics/lafayette_comstat_25_sch.pdf Yes, it looks like the 41.10 rock is the reason 4 channels are out. Here's how the synthesizer works: There are two master oscillators one for transmit and one for receive. One uses a 6.255 crapstal and...

100 amp sub-panel.

Experimenting is great. Don't let anyone including me convince you more than 3 radials is a waste of time and material. I wouldn't listen to me either.

That 3-500Z swap would be very worthwile if you are keeping this amp. To make it play would probably involve losing the choke input on the B+ supply and beefing up the filter for more voltage.

If someone plugged 3-500s in there it would have shorted the screen and grid bias supplies together. Your VR tOObs are still lighting so it looks like the screen supply is still working to some extent. If the 4-400s are blushing it is probably due to lack of negative grid bias. Maybe it was...

Top gizmos are 98% gimmick on chickenbander base station sticks. Mo-bile ants benefit anytime a loading coil's resistive loss can be reduced. Top loading does this by lowering the inductance necessary for resonance. You have arrived when your 75 meter mobile stick is resonant and you can't...

An inverted V can use any included angle over 90 degrees. The closer to flattop, the more the bandwidth and average height of the antenna itself. The feedpoint at 50 feet will work fine for regional 80 meter contacts. The way that band has been this winter you could work much further. If you...

There's a big difference between an alignment and so called peaking and tuning. I can show you a stack of 70s radios that are still working just fine with their factory alignment. Tube radios are not included though. People buy brand new radios and take them in to be hacked. Why not buy...

Look for a radio with an effective noise blanker. Some of the Sears Roadtalkers had a pretty good one. So did some of the Couriers. If you want simple, cheap and age correct take a look at the Sears SSB. Sears AM/SSB 23 Channel CB Radio SIDEBAND - eBay (item 230419848350 end time...

Thanks for the reminder. Where are my glasses......
