Re: HELP! With buying a new hf tuner

Want a good tuner? Depending on your power level, get either the MFJ 929 for up to 200 watts or the MFJ 998 for legal limit. Stay away from the LDG tuners. They are slow, noisey and are limited to only 800 ohms. There are other reasons to stay away but no use listing them here. If you are going to c...

Re: Can I tune 10,12, 15 and 17 $& 20 m?

Building and all band trap antenna is do-able. "Is it your best choice?" Probably not. You'll pretty much need a set of traps per band. With every trap you make the antenna shorter. Now you narrow the bandwidth per band. More traps, each band looses bandwidth. A tuner does not correct this problem. ...

Re: Kenwood TS-850 to repair or move on???

I am sure it's repairable. But the question is, " how much money do you want to invest in an old radio?" I had a TS850SAT from new. I think I had it for 22 years. It's really a great radio. I only sold it because of its age. I knew there would be a time that it would quit and did not want to invest ...

"Still under warranty !" Do you think so sweet pea ?

Selling and still under warranty ! Really? Is the warranty transferable? Show it in writing if it is. So many adds tell you that their equipment is under warranty. “Is it a total lie?” No! As long as THEY keep the radio it’s under warranty. Once you buy it, the equipment is no longer under warranty....

Re: Rant about newer transceivers

I have to agree. Trying to program these radios with just your fingers and the manual in front of you is a real pain. Hence the reason I ONLY buy uhf/vhf radios that can be programmed via computer. That's not to say I can't program one without a computer, but life is so much easier doing it with a c...

Re: Delta loop

The feed point impedance changes as you change the delta loops height above ground. It also changes as you move the feed point from the bottom to different points around the antenna. If you make a true delta loop with the apex up, the 4 to 1 balun will usually work fine if it's placed at the apex. I...

Don't for those guys that post a picture up side down ! My first impression, when I see that, is if the idiot can't even take post a picture, how could he operate ham gear?
As soon as I see an up side down picture, I exit and never ever read the add.

All good information above. Here's an added tip. Hook up your antenna, turn on your rig, follow the above instruction but also listen for the loudest receive signal while turning the knobs on the tuner. It doesn't matter if you hear someone talking or just background noise. When the receive signal i...

Re: 3-500Z amps

The answer depends on what you consider a quality amp? Are you looking for one that can handle 1500 watts out keydown in an RTTY contest? Then the answer is, "NO !" If you are looking for a great little amp that can be used in a contest for CW or SSB, then the answer is, "YES !" Ameritron AL-82 does...

Re: New Yaesu FT-991

The one advantage the FT 897 had was low current drain on transmit and receive compared to some other rigs, like the IC 7000.
Now that they changed to a bigger display, what's going to happen to the current drain.....going to go up?

OCF / parallel feeders

Never feed an Off Center Fed Antenna with parallel feeders. An OCF is not a balanced antenna and the parallel feeders WILL RADIATE and this you don't want. You would be better off using a simple dipole cut for the lowest operating frequency and feeding it with parallel feeders if that is the transmi...
