Hi all,
I have been waiting to see something better than vague sleeping theories.
Something that really kicks the brain to give the best it can deliver.
Click and see www.foc.us
Some other samples:
https://thebrainstimulator.net/
https://totaltdcs.com/recommended-tdcs-devices/
There is plenty on Amazon and eBay.
..who dares to run an amp while being connected to these scientific
equipment? !
For those interested in horoscopes, feel free to see www.OHDXF.fi web,
presentation Contest Station 2020 slide 32
https://asiakas.kotisivukone.com/files/ohdxf.kotisivukone.com/contest_station_2020.pdf
..roll to slide 32..
Remember Uniden 2020?
Or Galaxy 550?
Especially Galaxy 550 was a package way ahead of its time.
Just 2dB short of a full gallon by a small single package on the ham shack
desk.
I am waiting to see a kW out radio with FT1000D like package on the market
this coming year.
Happy 2020 everybody !
