Propagation is too good!

Getting used to good propagation is a quicker process then getting used to poor bands..
Again this morning/day 28MHz is complete filled with stations from 28.0 to 29.7  and even higher it is buzzing.

Only was listening 29.650 FM.  USA and JY4NE TA etc etc
The Steppir is doing fine but SWR is high at 29MHz and I could not tune it yet.
Tried long with TX7M on 40m but they could not hear EU  working JA and W's  559 signal good copy long time.

TX7M  now worked on 10/12/15/17/20/30
TX3T    4 slots
3XY1D   160m open
T32C  17 slots  not hrd on 80/160

Used DELL LATITUDE D420  notepad where offered 135€ at the "Dag van de radioamateur" radio market Saturday. 
Could not resist to purchase one. A low power/weight PC for WSPR intalled W7-pro.
I fact I like the screen 1280X800  is better readable then the 1980x1080 ...

WSPR 2.21 works okay using the internal sounddevice.
After adusting the line in  what is more complex in W7 compared to XP.
The ICOM IC706    tuned 80Hz up to correct the freq  
28124.680 kHz   output "L"  means little over 2W @ 28MHz

The homemade CV-I interface works with WSPR  but only if the DTR line is disconnected.  RTS is used for T/R
Therefore  I use a simple 1:1 back to back D9m-D9female interface leaving pin 1 6 and 9 open.
For N1MM logger pin 6 is needed  for CW keying.
So for N1MM the "interface" is not used.

And I purchased a Rusian tuning unit for lowbands  500kHz  Hoping we get a permission for 500kHz again.  Possible I can use it at 137kHz aswell .
It is a variometer L  with switchable taps.
125mm diam   L1= 22wdg    L2  71wdg 
and 2x  13wdg 100mmdiam  Vario L in between
