About those loading coils in the background....

Hi Allison, Unless I win the lotto (and probably not even then) there won't be a day when I spend a kilobuck on a radio. There might be a day when I buy a Spectrum analyzer (or make one). But there

Thank you for your answer! Well, does not post from a book, i have write my words and the things from the wire up shematic v1.9, is this not ok? does i make anything wrong whit dataprotect? please

So I have checked with the United States Post Office, and it appears that I will be able to simply mail the small external relay printed circuit board in a regular envelope, enclosed with a piece of

Bo Barry and everyone else. 1, I AM NOT dumping on Ian here.? I am trying to get him to pay attention to problems with his programming which he has chosen to ignore.? So DO NOT accuse me of dumping

... If "in the old days", enough people had access to Rigol DSA815-TG (Spectrum Analyzer and Tracking Generator) test equipment, NONE of us would have successfully built anything to get on the air and

Kees- Modern rigs, use diode switching to engage filters. I suggest using just 1 relay for positive switching and the output of each filter be run through diodes to a commonality. It would reduce

Hi Joe and all others in the group, I've been a ham for more than 60 years and have built several dozens of radio kits. I've owned the best equipment available in times past and having had years of

C'mon, total dumping is unfair. How much did you pay him for the code. Take that into account. Not sure but I think plenty of code is available to tinker with. The guy is gifted, keep him HAPPY.

Now with that said in my prior. The filter is fixable for 80/40/20.? dismount the relays, make some cuts and off to the races. Whine about doing that?? Time to do some basic technical work.? Your

What is the best impedance, size, and wattage for a speaker to be used with the ubitx version 4 board? I read someware 32ohms is this correct?? It may be hard to find tho. I found this speaker on

Are we ignoring the possibility of using series LC traps to suck out some of the bugs (bug traps...?),????? 8-) Arv, No not ignoring them.? They are generally useless as the assumption is the

Well said, Scott. We should treat the ubitx, and many other HB projects as radio 'build it" kits. I wonder how many other basement projects dont meet spec? I also totally understand where Warren is

Or maybe the website simply intends that under normal operating conditions, propagated signals don’t easily overload the radio.....which may be more true in some parts of the world than others.

Once again Iz, that is the point. You know.... and I know, how to recognize receiver overload and what to do about it. "does not overload easily" is subjective..... but when I have one rig out of

Warren, regarding '''The front-end diode mixer followed by a Hayward/Kopski TIA makes this a crisp receiver that doesn’t overload easily." Simply untrue. Using this receiver 3 miles away from a 1450

Thanks for the book. Chapter 2 is very important. If you want to use the chassis you need to be sure you insulate the tabs from the chassis.

All, as I have problems to upload the pdf files into Groups io I send them directly to the Group as an attachment. So let?s hope they will come throug! Henning DK5LV -----Ursprüngliche
