Thanks k5ess Frequency rolloff can be calculated using standard formulas for an RC network. Good practice for the radio amateur. Depends on the resistance of the input circuit you were driving with

FWIW here's my version of the Easy Digi.? I use it with a USB sound card dongle and a serial port for TX control. Mike K5ESS

So I swapped out my lm386 thinking that I might have blown it. Now I get ALL the am frequencies. Any ideas on what to fix next? ?Video included.

I am still fighting to get this working. While installing the first level converter I somehow managed to burn the Teensy controller- so I had to wait for the new one. In fact this project uses the

Dr. Ian Lee, Your firmware for the 7" Nextion displays is missing MANY of the configuration options available in the other display sizes. Please see photos for example. Forgive me if I am making a

Is oos, what computer program are you using?

Good info. I just received mine and wish the wireup on the hf website was updated. There is no mic and earphone jack hookup and mine came with a .1 capacitor. I found out where to put it on another

I'm not an expert, but that makes sense to me. In order for you to hear a tone from a continuous wave, you have to send it at a frequency offset from the receive frequency. 780 is a pretty typical

Hello! When I short the uBITX CW key on 7.210Mhz, the websdr shows 7.210.780.? So it looks like the uBIX shows .780k below the received signal.? ?Pls see the attached pic.? Is this an acceptable

I am not using the CEC firmware. Still the archaic firmware of early 2018. I am aware the CEC firmware is better but this simple hardware solution works great with my current setup. Il 05/mar/2019

I just received my new Ubitx version 5.1, got it all built and working but the readout is about 1300 hz below the actual received frequency....I have followed the directions for aligning the master

Are you using the cec firmware? I'm using that, and I think cec made the CW code work a bit better than the original .? Either way I'm glad you found a good solution!

Hi Brutus, Yes the S-Meter tap was designed with using the CEC firmware in mind! You can directly wire up the pad to A7(The purple wire). IT does require a bit of software calibration on your end as

Bill, more will be for sale soon as the pre-orders are shipped. Sorry I didn't reply to your e-mail yet I have been very busy getting them ready. Brutus, Yes! this has a tap just for that and has been

With an external key, Do you lose any dits or chopped dashes when the rig goes into transmit at this speed? I have been having issues with this problem from day one at about 22 wpm and above is when I

I'm using a simple transistor (non opto) setup for the cw interface. I found that messing with the tx -> rx delay really helped the situation and it now sends flawlessly. Was getting complaints of

Thanks Vic. I was hoping someone already had it resized. I wasn't expecting to actually have to do work!! :)

Mine is wired in the same way, for straight key. But the 4N25 was not enough. The sent code was really messy. Currently the 4N25 'keys' the 'Keyall HV' (mosfet) interface for any rig (tube as well)

I wired my ubitx for a straight key so I could use my preferred (AA0ZZ Ezkeyer from 4SQRP) keyer with it.? Later, for fun, I tried interfacing it via a simple 4N25 for DTR via USB serial keying, and

I suppose that there is a lot of variation in USB sound cards, but I had good luck hooking a USB sound adaptor directly to my UBITX microphone input with a stereo mini jack cable from the headphone
