Rob, It's why I have a 2nd one on order. I've modified this one about all I'm going to. My first one is my power outage rig and it works fine. Going to leave it alone. When the new comes in I'll

Would bn73-202 work with rd16hhf1 I got bn43-202 just getting the bits for the mod chris

Check that your key contacts are clean, maybe pull a sheet of clean paper through them. Then check the voltage across the key with a DVM, should be 5v with the key up, 0v when the key is down. If it's

Funny story, I actually ordered two copies on Jack's book. When they arrived, my 10yo daughter said "Yay! You got one for me too!" So much for selling that extra copy!

Greetings,? I just finished wiring up an original first run uBitx that I received late Dec. 2017.? I am mainly a CW operator and use a straight key 100 percent of the time. The original firmware I

Thank you for all the stories, I love hearing them and I'll bet others do too. I'm certain, now, that jumping into an IC-7300 wouldn't have supplied the same experience...not that I won't end up with

I made some Mixer PCBs to play with. I used an little more expensive match diode ring. The is a spot for matching transformers and a Pad Attenuator. I did use one and I heard signals, but did no

My point is, for some young person thinking about a career in electronics, the Arduino environment is not a bad place to start. It encourages exploring the interface between a computer and external

Michael, I got used to using a prototype board called a Surfboard. There are many different arrangements of pads. While expensive on a per-unit basis it works for me. You still have to cut traces to

James: I don't know. A lot depends upon your goals. I remember going to Cleveland for my draft physical (1960's) and hearing guys say they were going to intentionally fail the "intelligence" test.

Jerry: "The Arduino environment is not a bad choice if wishing to start on the path toward becoming a hardware or software engineer." I'm torn on this....necessary but not sufficient.... The

Both of my uBITX were shipped by DHL from India, one in December last year and one last month. Both where received here in California two days after shipment from India and without duty. Dave WI6R

I agree 10 watts is good enough. It does not make sense from the linearity, thermal and energy management to just gain half a true S unit. Also, to "nail" the output to what you can get on 10 m,

Thanks Tim and Raj. I'll go ahead and wire things up now that I know. Once I get the mixer soldered-up, I'll check it with my signal generator and scope. By the way, I do keep a journal: I scan most

I'm not convinced there's a need for continuous ALC during transmit But would be very cool to set the appropriate power out level when tuning up on a new band. Or better yet, tune up on each band

My Bitx40 Raduino, now spare as I bought Mike's RaduinoX, is making a fine VFO for my 4SQRP ZZRX-40 DC receiver kit. I'm using Allard's v1.26 code with a few changes to make it tune 7.000 to 7.300

Sounds like the one in How To Become A Radio Amateur. http://www.w7ekb.com/glowbugs/books/ar55how/index.htm I too built mine on the orange crate 'chassis', in '51. Them were the days! If the uBITX

My first transmitter (1953) was a 6V6 running at abouit 250 volts built on a piece of wood and with a single 80M novice crystal. Lucky if it got 5 watts into my random wire antenna. The term QRP was

I heard several voices Rhode Island, Chattanooga, Canada and some others. We had a snow storm during the day maybe my antenna was a bit shorted. Called cq bitx quite a bit and no response. Wasn't able
