[Elecraft] K4/0 bandwidth usage

[Hisashi T Fujinaka]

Just to be pedantic, network speeds are generally measured in bits not
bytes. It should probably be Mbps not MB.

18Mbps seems low to me, but I just asked my buddy who switched from DSL
to using a cellular modem and he said he rarely saw 1.5Mbps down and
0.5Mbps up.

I have a K4D and a K4/0 FieldTest unit connecting to servers at the station 60 miles from my home.  On receive, the bandwidth consumption indicator in both the K4D client and K4/0 client shows about 1 MB usage and a real tiny number for TX bandwidth.  I?ve never looked at the indicator while transmitting but I?ll bet the numbers are just reversed.  Panadapter information is not being sent while transmitting, I don?t believe, so bandwidth on TX could be much  lower than 1 MB.  I think you?ll have plenty of bandwidth unless your security cameras (or other devices) are also on the same ISP.  The K4/0 is just a very pretty (and portable) package and firmware is going through intense testing right now to get it ready for general release.  It is really amazing.
