Maybe it's propagation of I am too far away from everyone, but I heard no one. Lots of adjacent activity (7278) and I called CQ BITX once on 7277 but there were no replies. I also called twice on

got contesters on 277 kc2ipx

Anybody on 40m ssb 7277? @20:12 itch

Thomas Asshar does quote a perceived sensitivity somewhere, I am not recalling it. On HF its effectiveness in sensitivity should rival other rigs, except maybe at 24 and 28 MHz where is does not

I decided that I would go another direction for my low audio problem, instead of trying to insert a preamp I just am using the uBitx's audio amp as the preamp to a TDA2030 module, it works so much

A number I don't have. But that said it is comparable to my other radios. The big advantage that it has over the sdr receivers is that it can transmit, also you don't need a computer to make it work.

I do not have exact figures, however, the article in the description page says there is a usable signal at .1 uv .

Hello ! This is a very dummy question, but I can't really find the information... I would like to know what is the RX sensitivity of the ubitx ? I'm planning to use it (among other things) in my

FWIW, I find Parts-Express to be a really good and responsive company. I've purchased quite a few items from them, including a cheap solder station (<$15.00) and cheap speakers and have been happy

Holding the tuner button down when powering on goes into the three cal serial mode, not into the menu. Might still do what you need, but isn't necessarily the same. Reed

I have published a YouTube video that goes through my findings. I was also trying to explain how the circuitry works. I show spectrum analyzer readings as I explain it so it might

Thanks for providing this.

I've always had a thing for clear speakers...I mean how cool is that...hahaha. There is a price to be paid for that great small form factor...the efficiency is 84 dB 2.83V/1m. The bigger

Here is the signal pathway for a V3 uBITX -- 73 Dave AD0B Raduino bracket and Ham_Made_Keys ( http://veloliner.com/ham/k0mbtkey.pdf )

This one is for a uBITX V6 -- 73 Dave AD0B Raduino bracket and Ham_Made_Keys ( http://veloliner.com/ham/k0mbtkey.pdf )

Dear friends, I need help.. I accidentaly burned out Si5351 chip on Raduino on my BITX 40 kit TRX. So I removed Arduino and I decided to use RTC07S DDS VFO from hambuilder.com instead. It all turned

Great idea, Don. If you're looking for a smaller speaker with high sensitivity in the audio frequency region, you might give this one a
