I really fail to see a serious problem with this thread. Sure if ppl don't like a bit of controversy and vigorous discussion then by all means hide the thread but personally  I have learned more from this thread than any other I can remember in the bitx20 group.

Now Ill just have to build a couple efhw  antennas and and do some hands on testing.

Thin black wire is really hard to see.  I struggle to get the sun in just the right position to be able to shoot photographs of people can at least SEE my 3 antennas....  

300ohm window line is fairly  hard to see, also.  

I have made insulators from quarter inch plastic stiff tubes before.... left over from medical supplies. 

braided fishing line can be had up to 80 pounds strength, and it’s flat impossible to see, if you buy dark green.   I use bright orange to even have a prayer of finding it  after I shoot it over trees.

Run it to a balun at the back of your house. Instant near zero-loss center fed , off center-fed, whatever you want Antenna.

If you want vertical, run it along side the trunk of a good tree.   Or put in a really proud flagpole!

So, exactly what do you have in the way of a crappy EFHW, and what matching network?
Why is it crappy?
Then I'll know what not to do.

If you want stealth, that's a good way to go.
Some skinny wire, perhaps galvanized steel for strength, and a matchbox on the side of the house
are much harder to see than coax going up to the middle of a dipole.

Re: uBITx V3 Stuck in Transmit #ubitx

_Dave_ AD0B
 

I had a similar problem in that when I keyed the transmitter it would stay on. But was intermittent. I found I could tap the relay and it would turn off. Although sometimes it would continue to transmit with a high swr. I tried chokes but the relay was bad. I could tap on the relay with screwdriver handle and it would go back to normal. Also weirdly it had no power on 30meters. 

A new relay fixed all the problems. It was less than a dollar out of china.

I'm sure others will chime in but I remember Ryan Flowers doing a lot of experimenting with different bands on the BITX40 on his blog.  Search his site http://miscdotgeek.com/ for 20M.  I think Don http://www.nd6t.com did a band conversion too.

Re: uBITX HF transceiver and blue MBITX metal case.

Paul Galburt - K2AYZ
 

Hi, Jim

With regard to the demise of RS-232, it's important to remember that these same UARTS support RS-422 and RS-485 multi-drop. These protocols are still in wide use (particularly RS-485) in industrial settings because of robustness, simplicity and economy as compared with (for example) Ethernet in the same setting. USB is strictly point-to-point and, while offering good bandwidth, is greatly distance limited compared with 422/485.
 USB is also generally lacking the fully isolated solutions that are often required between "unfriendly" components.

For example, if you want to control something slightly smart up on a tower 500 ft away, isolated and slew rate limited RS-422 is the way to go. USB won't work and copper Ethernet's distance limit rules it out.. Fiber would be nice but gets pricy and complex - and you still likely need power wires.

In short, while most common applications of RS-232 can be replaced by USB (as long as you have some real smarts at both ends), the RS-422/485 applications are still out of reach.

Just my opinions, of course.

73,

Paul K2AYZ
