Endian issues...final chapter
All: Jerry and I have continued to argue offline about passing data between machines that use different endians. (The endian idea is that an int data type can be organized in Big Endian or Little

uBITX Firmware CEC Version Added WSPR function, I am looking for a beta tester. #ubitx
Hi Ian Thanks a lot for the latest update with the wspr function. It is now working fine after adjusting the tx frequencies by hand for the 3 chosen bands, 40, 30 and 20m. The signals have reached all

Re: Pulling Arduino data apart
Take a look at the wikipedia entry down at Files and Byte Swap. That shows that machines that use different endians must account for it when reading data, be it from a file, a DB, or a COM link.

Re: Pulling Arduino data apart
Sometimes I wonder how many of those who are new to BITX, Raduino, etc. are becoming confused by discussions of "big-endian", "little-endian", and "non-endian" by thinking that this affects how they

Re: Pulling Arduino data apart
The Wikipedia entry is a much better starting point than my previous stackoverflow conversation: ? ??https://en.wikipedia.org/wiki/Endianness Also this, do a search for "endian": ?

Re: The issues of the TDA2822
That¡¯s a great question. Mine was shipped two days ago. Will it come with a 7822 that won¡¯t require any mods? Thanx-Gary

Re: The issues of the TDA2822
" We finally located a source of brand new, high quality TDA2822s that are currently being shipped." I placed an order few days ago... Does that mean that I will have normal chip that doesn't need any

Re: Variable power control
I have been powering my bitx40 with a 3s Lipo battery Nominal voltage 12.? last night I thought maybe I could put in a LM317 and set the bias for 12 v and power the radio with a higher voltage lipo.

Re: uBITX Mic Wireup
Connecting the Mic- to ground to generate PTT is common for many handheld radios. It saves a wire in the cable. You¡¯ll need to rewire the Mic and PTT SW to work with the uBITX which is exactly the

Re: RD16HHF1 power curve flattening...some
Not yet, I have decided to re-model the case, and install my RaduinoI2C board... Also mounted a swr bridge... Gonna be a nice little rig if I get reasonable results from the PA mod.. 73..

Re: Variable power control
Good thought, Marco. But most. if not all variable VR's have a fixed or lesser VA output. IF you lower the voltage, usually the available amperage goes down as well... I use two in my bench supply,

Re: uBITX Mic Wireup
Shaun, The ubitx doesn't have a balanced mic input, i.e. mic leads that don't have one connected directly to system ground. In a balanced feed the shield wire would be the system ground and would act

Re: The issues of the TDA2822
This is the modification I came up with to implement a 7805 to supply the TDA2822. Please check it over for errors.? One trace cut and scrape a little off the board and solder in the 7805. Ron W7HD
