Re: Commercial Linear amplifiers for UBITX6 and other QRP transceivers...
I can't seem to find the amp you are talking about. Can you post a link please. Max KG4PID

Battery Pack
#ubitx-v6
Since I'm still stuck in bed I have been working on a uBITX v6 basic kit. Since I'm in bed I am unable to run a power cord from my power supply to the uBITX. So I have been using a little battery pack made up of 8 rechargeable AA batteries. It has 12 volts for a bit but that is about it.?
I'm guessing here that the three-wire connector P1 is for an optional battery pack.? I'm planning to have some surgeries after the first of the year on my back. I'm planning on being able to be active then and I want to get back into riding my recumbent trike and operating the radio from city parks.? I'm interested in having an onboard battery pack for my uBITX. Has anyone added a battery pack and if so could you please tell me how you did it and what batteries and associated parts did you use?? Thank you -- '72 Aaron K5ATG |
Re: What's New? NANO every
Hi Mark,
I have more or less finished boxing up the uBITX V6.
It uses the stock KD8CEC firmware on the Arduino Nano for the uBITX.
I decided to make all of the additional features separate to the Nano, using a D1 Mini ESP8266 module for control and monitoring.
? 12V reverse voltage protection and in-rush current limit.
? 5V, 1A SMPS for all additional digital logic and Nextion display.
? Voltage and current monitoring for 12V, 5V and 3V3 rails.
? RX audio with SSM2167 (AGC) and LM386 amplifier. Volume and AGC configured via digital pots.
? TX audio with SSM2167 (AGC). Mic level and compression configured via digital pots.
? PWR/SWR bridge
? Provision for temperature monitoring.
? Cooling fan controlled using temperature and/or supply current levels.
? OLED display for Volume, VI monitoring, Pfwd/Pref/VSWR and other parameters.
All addon features can be controlled/monitored over WIFI using MQTT with NodeRed.
I may add a serial bridge between the NANO and D1 Mini to allow for WIFI control and monitoring of the uBITX (using the CAT commands).
A few pictures attached.
73, Dave

Re: uBitX40 with Raduino V1.29 DDS on CW?
¿ªÔÆÌåÓýHi Paul, make sure that semiQSK in ON. If it's OFF, the mode selection toggles between LSB and USB only. If it's ON, the mode selection rotates through LSB - USB -CWL - CWU Keep the FB pressed for more than 3 seconds to go to the SETTING menu. Then do 2 short presses on the FB to go to the CW parameters:
Hope this helps. Happy BitX-ing! 73 Allard PE1NWL November 18, 2022 4:13 PM, "Paul Bigwood" <paul@...> wrote:

Re: uBitX40 with Raduino V1.29 DDS on CW?
Not familiar with the original Bitx40 code, but there is no special hardware for receiving CW.

So receiving CW in LSB is correct, the only issue is that the display frequency will be off by a few hundred Hz.?? Most Bitx40 users replaced the code it was shipped with to Allard Munter's code: ?? The "bitx40" code in the upper right of that page requires no hardware mods to the rig. The "bitx40-raduino-v2" code in the upper left does require some easy mods, giving many additional features.

uBitX40 with Raduino V1.29 DDS on CW?
Hi,
I'm trying to get my old uBitx40 V3 board with Raduino V1.29 completed!? I bourght it years ago and never completely installed it into its case until last month. I'm having some trouble with selecting CW mode. I unerstand that 4 presses of the function button takes me to the Mode function and I should be able to select selectr CWU or CWL by rotating the Tuning knob, but I only have LSB and USB selectable?? I can select Straight or Keyer from the Settings menu OK.? when i try and transmit CW the radio is switching in to CW on YTX but into LSB on RX. the CW is very choppy.? I have added the CW mod to the DSS board and the keying lines for the paddle. Any idea what may be wrong?? Is there a later version of Raduino code suitable for this version of Bitx40? 73 Paul G3WYW |
Re: need tool advice
¿ªÔÆÌåÓýMike,I use an older version of this one: I have two of them, one with a fine tip and one with a broader thicker tip going all the time when building. ?I have used them for maybe 20 years with good results. ?Mine were half the price ¡°back in day¡± when I bought them. ?Ha!?
