Re: ZachTeks Summer Sale is on!
I just ordered 3 ZachTek 40-6 version. The 30% sale is thru Monday 7/8 The savings will more than pay for the DHL Express mail. ?I agree with Hiroki for virtually being indestructible. ?I have repaired a couple xmtrs where the line driver IC shorted. ?One had an output shorted to ground and may have been infant mortality very early in use. ?The other was an input shorted to ground issue and had run for almost a year. ?It was located in Nevada and owner thought possible lightning nearby. ?My thoughts were if lightning, other parts would be damaged. ?Only one line failed. The part is cheap but requires Fine Pitch soldering capability. ?Tiny part. ?Harry of ZachTek sent me a 1/2 dozen parts, otherwise I would have to order from parts house. ?Anchor Electronics does not carry that small device. ?Neither Jameco also.
?Take advantage of the sale.

Re: Chelegance MC-750 Clone from Ali Express
I have 3 in use with ZachTek xmtrs on 30, 20 & 15 meters WSPR. ?Just received 3 additional antennas with cost for $29 each. ?They came in 6 days. ?Will be setting up for 17, 10 & 6 meters. ?
The ZachTek xmtrs can handle high SWR. ?The Xmtrs are within 3 ft. of each antenna. ?Running 24/7 and each xmtr is single band with no rest period. ?Each antenna is at full length and counterpoise is not separated for the bands; just laying on ground. ?All 3 antennas are within about 3 ft. each other. ?
Using WSPR.rocks - look at my spots.

ZachTeks Summer Sale is on!
Here is an opportunity to get a ZachTek WSPR xmtr cheap. I find the ZachTek a best made device I own. I often let it run 24/7 to check the HF condx. I have several times inadvertently transmitted with high SWR but the machine is indestructible.

It always seems to feel 10 degrees cooler there, maybe the breeze or the water temp? ?I¡¯ll let you know how it goes. Pete Mahowald | pmahowald@ me.com | 650 492-3989

?I agree with Cliff..... not that I really think you are nuts but I'm afraid I would melt. It's supposed to be a high of 89 at Baylands on Friday. I have a very narrow comfort range and 89 is out of my comfort zone.?
Cliff, are you really going to stop by?? If you are I would make an effort to stop by for 15 mins, then return to my 78degree cave. Text me please if you do plan to come.?

Chelegance MC-750 Clone from Ali Express
I know you all are anxiously awaiting this review.? ?Well, here it is anyway.? The antenna arrived today from China.? ?How is it?? Not bad.? It's not an MC-750,? but it didn't cost $180.? It was $27.67, delivered.? ?Here's the picture of what you get. Quality,? not bad, certainly good enough.? ?If the MC-750 is a Cadillac, the clone is certainly a Ford.? The whip is 5.6 meters long, has double crimping and looks like it will last.? The red mount is very well done.? Take my word for it, you don't want to take it apart, it's well built but not easy to put back together.? ?The stake is a stake and does it's job. How does it work?? Just as good as the MC-750.? ?I can't hear any difference on a - b switching.? SWR is the same.?? Bottom line, it's a good buy and I? don't see any reason to buy the Chelegance.? ?It sets up in less than 5 minutes and tears down faster.? It's perfect for the Baylands.? ?Cliff this is perfect for the Ship.? Handles 300 Watts. Questions???

You folks are nuts!? 98 degrees!?!
Errrr, uhhh, I admire your enthusiasm.? We might be able to stop by.

Re: I need some advice making a new 20m dipole antenna
OK since I want a dipole it's 1:1 balun then.?
Thanks, Joy

Re: I need some advice making a new 20m dipole antenna
49:1 is good for end fed half waves 9:1 is good for non-resonant end fed wires (aka "random" wire) 4:1 is good for off-center feds 1:1 current baluns, also known as common mode chokes, are a good idea at the feedpoint of dipoles that are coax fed but not always necessary

You can build it in various configurations.?
- Male BNC for direct attachment to radio
- Can be built for use on HF bands from 160 m to 10 m
- Build as a 49:1 Unun, 9:1 Unun, 4:1 Unun or 1:1 Balun - Just add wire to complete your antenna
- 5W max for high-duty cycle modes, 10W max SSB
I want to build a 20 m dipole. Do I want the 1:1 Balun? I think that's it but I want to be sure.?
Thanks, Joy N6GO

I will wait for Doug's experimental methods in RF design pulling RF from the sky.

The MC-750 isn't less than $50, but the clone is.? My parts are supposed to be here today.? ?I can't wait.?

Bob,
The reviews on this antenna are not particularly good.

I think I will be at Baylands with an FT-817 and a raised radial vertical made from an element from a triband yagi.
