Yes, J1 and NOT j2. Anyway , the circuits works very well for AGC and the s-meter function. Thanks for it and K5BCQ for putting the kit together at his cost. Ralph ku4pt

What does this have to do with the BitX radios? 73 K5KDT Kevin

I used a .22ufd but it is not critical so near anything close will work.

Mark Maybe your S-Meter is good. It is a circuit composed of about 4 parts and it will work if only the power is connected well. Depending on the voltage measurement method, the value may not

I have my ubit x installed in a nice aluminum case and powered up. It draws about 89 ma on receive, and receives stations. but the stations are garbled as if the BFO is off. Also Transmit only gives

Very funny...... do you have additional details ? 73 Kees K5BCQ

Way off-topic, unless there is a BITX somewhere in the Internet backbone architecture. _._

Simple answer... since I first got my ticket in 1980, I've heard of several attempts by corporations to take over Amateur Radio bands for their own use... and read of others going back through the

Thanks for the input, guys! I was working with no magnification and "regular" soldering tools. Sounds like the right equipment would open up a whole new world! .....:) Will follow up. Tom AB7WT

Howard, just to verify for two purposes, 1) verify they will work, 2) If not, learn what I did wrong in picking them! From DigiKey I am looking at: Inductor: MLF2012C270KT000 445-1064-1-ND FIXED IND

On their website you can download the schematic. They are a bit obscure on the mosfets, it seems they are four MS1307. As said they lack of any lowpass filters so as such they do not comply to the FCC

The MS1307 seem similar to the IRF520 btw

I use the CTE Booster 747 amplifier modified like this : www.radioamatoripeligni.it/i6ibe/pdf/cte747.pdf It works well , up to 80w on 40meters . I only need some ebay hf lpf's .

Try this, https://groups.io/g/BITX20/message/47890 I found this method of Calibrating the BFO to be pretty straight forward and will put you pretty close. Your audio will improve greatly and your

Not many of us need to use 0201's. Thank goodness. It's like working with grains of salt from the salt shaker. For hobby work down to 0603's (half the size of the uBitx's 1206 parts), reading glasses

Oh yeah, I forgot to mention that someone on the board has advised that you should cycle the radio off and on each time you calibrate the BFO so that the setting "takes". Not sure if that's true or

Was on the boat last night and only barely heard one station coming out of the noise.. need a bigger boat so i can plant some trees for my windom hihi. Anybody ever shunt fed an aluminum mast or

Sounds like I need to get my 6 meter transverter built, put my tower up, and put up a beam. 73 Bill WA8VIH/4

I bought one of these out of curiosity more than anything but if it worked I was going to use it as a 40M only amp while operating mobile with my scratch built Bitx40. To my surprise it worked pretty
