Thing about TVI, most cases it is poor filtering built in...
to get the CE rating, you have to have filtering to a certain standard but nowadays it's all chips etc which are very susceptible to RFI...
the rules have been weakened over the years...
it used to be if I had a test transmission, I had to log it and any other transmissions I made, contacts, time, location, power etc but even that is no longer the rule, I don't need to keep any log...
Too much cheap imported electrical equipment with insufficient filtering...
I use internet boosters which have been fitted with filtering for the ham bands and they work excellent.
Anyhow, 77 contacts, I just had enough...
I'll send my log and wait and see, hopefully top 100
I use an 9:1 UNUN and 7.3m of copper wire...
(my loft space has I dunno how many antennas up there
)
