Re: New nano board displays only "ubitx v4.3" #arduino #bitx20 #bitx20help #antennas #audiocircuit
Thanks yes I did. I took the digi board completely out of the loop. If I put the original nano in the radio acts as a normal v 4 ubitx. I can't figure out why these replacements won't work?

Re: New nano board displays only "ubitx v4.3" #arduino #bitx20 #bitx20help #antennas #audiocircuit
Somewhere I read that after some changes were made, the V6 had to be turned off and back on for the changes to take effect. I think there was a few seconds delay in turning it back on required (in the

Re: #v6 connect ubitx V6 and Xiegu XPA125B #v6
You would need to key the V6 on the freq you want to operate long enough for the tuner to go through the tune cycle. Otherwise, there should be no problem using it with the V6... I am getting ready to

Gary, Did you try powering up the rig without the USB connection to the Nano from the digi board?? There may be an issue with the digi board. 73 Evan AC9TU

Re: Kicad files
Sometimes you see a Hotwater-8 or an HW7 (the -8 is more common) at a big hamfest going for $50-$125, depending on condition. They are usually bought for nostalgic purposes since in their heyday, they

I don't think I worded my first post very well. I am trying to install a new nano board. The v 4.3 sketch loads properly no errors when it compiles or loads. This board seems to be the identical

#v6 connect ubitx V6 and Xiegu XPA125B #v6
Has anyone any experience or comment to make of connecting the V6 to a Xiegu XPA125B amplifier. I think there should be no problem but I would like to consult them if anyone has any comments on this.

Hi Gary, I flashed a spare Nano or tried to using the IDE Software with verbose ticked for the Upload option. It kept failing with a can't sync 500 error. I found I had to select the OLD BOOTLOADER

Re: Kicad files
HW-8 (HotWire-8) was a single-conversion transceiver by Heathkit, from the 1970's era. Not really relevant today because of US FCC requirements regarding spurious emissions. _._

Re: Calibrated now no receive.. Ubitx V6
Jerry, Great info and thanks for the input. In hindsight I added the zeros to match the info kindly provided by Reed N. I actually just turned on the Ubitx V6 and the additional zeros were not

Re: Calibrated now no receive.. Ubitx V6
There's a PLL inside the Si5351 that locks the nominally 875mhz VCO to be exactly 35 times the 25mhz reference oscillator frequency. The 25mhz reference is usually off by 100khz or more, we must

Re: Automatic antenna tuner (N7ddc) and loop antenna
Hello, Yes,?Yes, I made a collection of favorites on the subject. I wonder if my order of this N7DDC antenna tuner is useful for a LOOP antenna. A priori NO, because this does not affect the main

Re: Automatic antenna tuner (N7ddc) and loop antenna
Otherwise, I wonder if the change in the value of the capacitor on the LOOP antenna, will not actually cause a runaway system....because autmatic Tuner will adapt new value, etc Another track to dig

Thanks Jerry, Concerning the tx, we are not working on HF ham bands. We'll use an experimental license (if it works ok without the SSB filter), in order to carry the HF wide-band experiment. Rafael

Re: PA rx/tx and swr protection connection to ubitx / arduino nano
Thanks a lot, Reed. One pin will be enough. As soon as I finish the swr protection circuit I send here - one idea is just to signal the "cut-off" signal, other will be send a signal in voltage range
