No idea but something must be wrong either on the ubitx, connections, wattmeter etc. You should see at least 10w on 7Mhz. On mine I see something like 14w on 7Mhz decreasing to less than 2w on 28mhz.

Hi UBITXers I just put together the UBITX and it puts out about 3watts or so on SSB on 7mgh. Nice clean wave form on SSB and CW and I've had a number of SSB QSOs. However, on CW output is only about

Also, my power supply is only 1.25. Is that enough, or should I get a bigger one.

Hi, My volume control knob is a discarded cap from a medical syringe that had contained saline solution. The threaded hole that once sealed the syringe is the same diameter as the shaft on the volume

Since I have been monitoring all of the Bitx threads (only for the last 3 months), I have come to understand that the uBitx is a kit that really needs to be worked on to make fully "legal" in the USA.

I saw somewhere a comment about the knobs. The encoder knob is not a problem since it has a pretty much standard size shaft diameter. However, the volume control shaft is smaller. I've seen knobs on

The BITX radios are open source designs intended for hacking and learning.? They're not intended to be and likely never will be appliances.? The info's here on the forum - grab a soldering iron and

Yes. The community is also working it. In my dreams someone will offer a kit of parts, that has been verified on maybe a couple dozen rigs. Meanwhile,? available data may give you clues on what bands

The fact that it is V4 would suggest that improvements do occur. There many great and wonderful minds on here working to improve the uBITX. For that I am thankful. Merry Christmas and a Happy New Year

Mark, thank you!!!!! This is weirdly white knuckle if you are a newbie...but i will wear down the problem.? Thank you the assistance... Don km4udx

Nice work Jack, I saw the pictures. The teensy audio library is very flexible. I am experimenting on the m4 cortex at a very low level but using the CMSIS framework, it seems good, it is not as high

Hi Farhan, thanks for reply, obviously it is an honor for me to have your attention, thank you. ofcourse it is possible to port it to other platforms,?some months ago I worked on small audio

Installation info on web. It shows exactly where to cut the trace to install the version with 2 mosfets. The detector attaches to the high side of the volume control. The mosfets patch into the RF

Thanks Mike...? Found 1621s on ebay for <$6 and total of $5 for shipping.? Ordered 3.? Might take a long time for delivery.? I didn't spring for the $30-$35 shipping for three 8-pin dips! Woody

Just a quick question, is it just for smoothing? Could I get by with just bridging the connection? Sent from my Huawei Mobile

i suppose ebay is offering 10pcs smd version at less than $3 and free shipping.

Ebay offers shipping of $2 or $3 from China. Mike K5ESS

Have used 8307s in several projects. It is a log amp with rather high freq capability which can be tamed, but it does not offer the attack / decay features of the SL621.?? Still, a possibiliity.

Farhan: Check out the video at: http://hamradiodesigns.com/index.php/photos/ Some of this is already being done. Jack, W8TEE

great news. perhaps if you stick to straighr c code, we could pull this into other platforms like rpu and teensy?
