Re: Very low power output (BitX40), everything appears to be working but setup driving me crazy!
Jerry, Great, thanks, will give it a try. Sounds simple and will be a good way to check my cheap CB watt meter. Gene N2IJF ________________________________ Sent: Saturday, December 30, 2017 9:46 PM

Re: Laser cut ubitx case SVG
Nice design. Perhaps we can manage spot welding 4 nuts behind the lcd and thus prevent the 4 mounting holes. Kindly think of such possibility. best of NEW Year 2018 regards Sarma

Re: Very low power output (BitX40), everything appears to be working but setup driving me crazy!
Gene, What frequency did you test on, and did you try other frequencies? It turns out my Bitx40 shows different output levels depending on the frequency across the 40m band, maybe your board has the

Re: Very low power output (BitX40), everything appears to be working but setup driving me crazy!
Yes, you can use it without the Nano. Assume the transmitter is driving the 50 ohm dummy load with a 20 volt peak to peak sine wave. Since the other end of the 50 ohm dummy load is grounded, the 20

Re: uBITX Case
FYI, The Ubitx does fit into the Excellway case but it is a bit tight. I managed to get a hole cut into the front panel that just fits the display and leaving room to the left for the vertical screw

Re: How to find the missing "Low pass filter at 30 MHz" article by W7ZOI #ubitx
I don't know what specific parts W7ZOI used.? There's very little power flowing through this filter, though, so it should be easy duty for the components. I used these:

Re: ALE, WINLINK and uBitX
oK, first success on ALE with a uBitx --- KM4ALP is one of their monitoring stations, and bingo, when I transmit (10 W out roughly) on 80 meters,, he picks it up! I show up on their map with a link to

Re: Very low power output (BitX40), everything appears to be working but setup driving me crazy!
Hi Jerry, Sorry for the delay (holidays you know). I do have a number of the 100N50 resistors and find that they work great. Yes, I saw the notes from Jack but I am unclear about the operation.

Re: Tuner? Well Sure!
Well 160 will easily be covered but 630M is a much larger task. The efficiency of a wire that is less than 0.2 wave lengths (close to 400 feet!) on that frequency with a tuner is extremely low (most
