Today - after abt 1 year abstinent - I grabbed the uBITX V 6 - assembled 2020 January For my CW (QRP) operating - It has modified with - Nextion Desplay - AGC from Kit Projects - Audio Filter from

I routinely use this Lithium pack with my uBitX V5 to run portable. It is handy in that it has a 5v USB socket for the little RPi Zero 2W that handles digital modes. I have run all day on a charge and

Thank you for the info. I'll read the manual. -- '72 Aaron K5ATG

Sorry - i had the name wrong. /g/BITX20/files/uBITX_6_N8ME_2_VU3GAO_Mods.zip This is what I was referring to. Gerry Sherman Sent by the Linux Thunderbird

Where can I learn more about N8MM/VU3AGO software? That sounds new to me -- '72 Aaron K5ATG

Another option is Lion Batteries. They are small and are not as limited as other types. My son in CA (N5DIM) goes mountain-topping and has a go-pack and he uses Lion. He said there are sources for

Yeah Gerald it looks like an external will be the best option. Don't put it off too long or you will be stuck in the hot humid tropical weather that Canada is known for lol. As for the AA battery pack

Aaron - I am planning to run mine as a portable.? I will be using an external battery.? I have a couple of LiFePO4 4-cell 9 amp-hour batteries.? One of them should be good for several hours along

Hi Mark, The main reasons I used the I2C mux was as follows: - It reduces noise caused by reflections. I actually added series resistors on the I2C connection from the ESP8266 to reduce edge speeds. -

Other than level shifting from 3 to 5v, what does the I2C mux do that simply connecting the devices to a shared bus does not?

Hi Mark and Jim, I only have a basic block diagram (see attached) and a few notes below. If you have any further questions I will try and cover them. Each function is built on bread board and/or

That is really nice! I am sure a lot of us would like to hear about what you did with the ESP8266 module. I purchased a replacement Nano Every and trying to figure out why 2.0 doesn't like it. I have

While I have built several amps the general thing is at home if I need more than 50W I just power up the 100W radios (TS440A/At, Tentec Triton, Tentec Eagle, or IC7300).? I feel none of the QRP

A good option for a battery pack is at Rural King, if you have one there. They sell a 6V gel ccll battery for deer feeders and two of them cost me $20 and when the two are connected in series (watch

Thanks Evan, since there are products from Softrock and Hardrock I was confused (easily done now days) Max

The general application is a 12V pack suitable for 10W radio.? FYI AAcells will not have a great lifespan not enough amp hours. An onboard pack... how big is the radio?? how much room?? Generally

Max, I believe that he meant Hardrock 50.? At least that matches the description and the press release on a 100wat version now available.? We have had some of our club build club builders build that

It was clearly Farhan's Daylight Again rig that launched the current wave of PTO-mania.? Interest in Glue-Sticks as PTO mechanisms has also spiked.?Here is an article from 73 Magazine in 1966 about

Hi Dave It would be interesting and helpful if you could start a new thread and share more - many more details how you did what appears to be a really incredible build. I believe a bunch of us would

I can't seem to find the amp you are talking about. Can you post a link please. Max KG4PID
