Hi all,
in the mean time I have update Weekender firmware. With a help of Marko, S56FGS (who wrote PC SW) we have sucessfully rewrote firmware so that Weekneder channels can be easily updated via Marko's PC software.
Whether you're from the USA, Downunder or from the EU you can write your simples and/or duplex channels/frequencies with CTCSS included and upload all data to the Weekender.
You're invited to download files from Github. In the files you will find manual how to use SW to upload new channels/frequencies. You can use this or this serial adapter for uploading SW to the Weekender.
Happy Weekending :)

PS: note that all past Weekender owners will have to update FW within AVR chip. There is a FW file at Github for that, but to do that you'd need an AVR programmer like this one. If you're not into AVR programming you can still order already preprogrammed AVR chip wiith the latest Weekender firmware.
PS2: all files on my entire web page are available only for personal use! For any other use (workshops in HAM radio clubs & HAM associations is prohibited!
