7plus.zip ( 7plus.exe ) concerns a program which is very useful in combination with packet radio. It splits up the main file in e.g. 10 smaller that then by means of packet radio are sent. Including error detect. It repairs damaged files in a perfect way. To files which are exactly equal to the originals. I have often used this aforesaid program. It was frequently combined with the uucode programs. For most of the publications, which I uploaded in the packet radio network, including ampr.org applications. That is Internet for radioamateurs. A Internet connection via cable was not necessary. With help of a Commodore 64 and external controller ( to make highspeed packet ) a lot of bulletins ( including pictures and schedules ) have been sent over the Internet for radioamateurs. The whole website ( pa3gje ) in qsl.net passed firstly the ampr.org.netwerk. Still the concerning programs are entirely useful.
