Hello ! Here it is : https://drive.google.com/open?id=1hhT834HwT4gM5bP21fYhNoPKIvNzeVqI You can also visit KD8CEC' site who wrote new firmwares for V5 and needs beta testers http://www.hamskey.com

you can generate a tone at 1 khz from here: http://www.onlinetonegenerator.com Once you connect your pc to ubitx, measure the audio at mic input to be 50 mv peak(100 mv peak to peak). Then you can

help where can I find v5,1 hex file? I can not compile v5.1 in ide I need? help thanks John wb7wqk

Hi hf signals or home brewers.?If I can not successfully load new firmware 1.08?into v4 raduino.to fix low audio problem.?can I purchase a new v5raduino.( and the approximate price )and will it

Jim is operating in CW mode, CLK0 and CLK1 shut down, so no 2x45mhz=90mhz harmonic coming out of the IF amp to create the 16mhz spur when operating on 10m. That spur check will have to wait for his

Hi Bruce thanks so much for the info on down load .will take bitx and down load to club tomorrow .let you know how it goes thanks again .Will Bennett VK4WBX

Hello Jon, To identify your uBitx board version, look near connector P2, it says "uBitx Vx". Then have a look at this post below which points to the wiki from where the various schematics have been

Harvey, Disconnect the power wire to the PA, i.e. center wire on power plug and then make measurements. I suspect that 400mV is the L5 picking up PA signal. The level at L1 which is input to PA I

Jon V3 has the TDA audio amp. V4 has a discrete transistor audio amp. New V5 has a LM386 audio amp, and some new refinements including a different 2nd IF. All factory versions are supplied with IRF510

Jon you don’t say when you received your uBITX. If our board has the discrete transistor audio amplifier then yours is a version 4 and the 2018 schematic is correct. There was a long thread about

I have 2 Raduino's that were removed from working bitx 40 radios for sale.? $60.00 shipped CONUSA only for the pair.? Both have original software.? one has original 90 degree pins the other has

I have a 2018 and a 2017 schematic and neither match my radio. 2017 layout has a TDA2822, my radio does not. 2018 layout has RD15HV1 after the IRF510, my radio does not. Is there anyone have an

Hello Sascha, It should work "in theory" without a level converter (but it does not hurt to verify). Reason being is that "A TTL input signal is defined as "low" when between 0 V and 0.8 V with

So, after googling a bit I think I have a suspicion. While the Nano in the Raduino is a 5V System, the Teensy 3.2 runs internally on 3.3 Volt. Then with the additional 1k resistors in the Teensy RX

Hi Will, The youtube video? https://youtu.be/fxquxqv7fAA Has a link just below in the message pull down area. http://www.hamskey.com/2018/05/ubitx-firmware-cec-version-108-release.html?m=1 Where

Hello Sascha, One good news is that you have a USB-TTL converter that works and that it talks to the Arduino. Based on the above my first thoughts about the issue are either the option selection in

They have the same dimensions and a V5 will physically fit in the same box as a V3 or V4. You cannot use the Raduino from a V3 or V4 in a V5 as is, but they will work if you load V5 software into the

Jim, thanks for running through these results and posting them in as unvarnished a way as possible. :) It certainly helps those of us who don't have access to such a nice SA to see how things are

On the bright side, the 45 MHz into the final mixer spurs seem to be cured on this one sample. Are the relays same make as v4? I understand they are arranged differently on the schematic.? Maybe like
