Thanks for the information. I have returned the signal generator (off brand) that I got from Amazon that was DOA. Will check out the links to the Nano VNA and see what I can find there. Thanks to all.

I was wondering if the Nano VNA would graph it out. I ordered a signal generator which arrived yesterday DOA, and has already been sent back. I need to take a look at the Nano Vna. Thanks.

Disclaimer!!! I have no idea what I'm doing, but it sure is fun anyway. Does anyone have a clue as to the bandwidth of the bandpass filter on a Bitx40 or Easy Bitx? My breadboard version looks to be a

A big shout out to those that got me lined out on the crystal filter for the Easy Bitx. I finally got to the point of powering it with the VFO/BFO connected. I don't have the BPF parts yet, so I conne

There are some pretty amazing engineers, and technicians in this group, that go above and beyond. I started this project because I knew I could use the learning experience. Thanks for the help.

Thank you. I'm not a technician, or engineer, and I was confused. Thank you for the help.

Does a crystal filter pass audio frequencies? I am working on an Easy Bitx board and following the steps from the inkits website. I am at the end of step 6 where it says the following about testing...

The bitx40 was therapy for me when I was diagnosed with a serious medical condition. I knew that through the time of treatment and decision making, I needed a project to keep both my hands and mind bu

Its been a long time since I built the bitx40, but when I did, I saved the schematic to a file and sent that to a commercial printing company. I think I got 3 copies on huge paper for somewhere around

The Koss cs100 has an electret element and works well. I have one that I have used. Someone else on this board put me on to it. They are now about $20, but not long ago were much cheaper.

The crystal is not "bad" http://www.hamskey.com/2018/05/frequency-adjustment-of-ubitx-si5351.html

Being 1khz off is not "normal". It needs master calibration adjusted, NOT BFO CALIBRATION. Mine is hardly ever 10 cycles off.

It appears to me that your rig is coming up in transmit. I would take a look at the line for the CW key. Maybe something is not right with the 4.7k resistor that is supposed to be connected, or maybe

With a bitx40 detuned to 2 watts, I rag chewed for about 30 minutes with G0EVY Dave on 40 meter SSB. I do admit, Dave's monster antenna was probably doing all the work. QRP SSB DX is very possible, bu

I too was wondering the same thing. I would think if you are using a resonant mono-band antenna, or using a tuner to tune the antenna that the harmonics measure at the output would have an even less c

I just added 3 extension switches to my uBITX last week with ver 1.08 and all worked well. I did select the 5 sec delay, and I did make a small wiring change just to make wiring more convenient for me

With my radio/engineering skills very much lacking, I probably don't even need to be trying to contribute to this conversation, but here is what I ran into on my build. My tx audio was very distorted

Used the stock mic element. Added the wind screen. I think 10 for 5 bucks from Amazon or ebay.

Just gotta figure out how to get some labels on these switches and knobs. I did not stray much from the well known modifications. I did wire the KD8CEC extended switch mod slightly different, using a

Band is pretty squirrely, (arkie slang), but still able to work N4DKD, KN4CCQ (QRO) and on the ubitx K4BBN, KD8WTB (weak) and AA4PG (extremely good sounding uBITX using 2.8 Nextion display). The band
