K1N

Saturday early morning K1N 1817.4   strong! to 589 big signal for 160.
That should be an easy one call QSO..  hahah I did not knew then that I better went back to sleep...
k1n_160_1.mp3

One time responded PA0 but never received my full call then they went on with an Italian.
Hard to understand that with such signal I could not make it.
I used to have a decent 160m signal even with low power and thought it be easy with such signal. Should have known better eorking DXpeditions with the QRP ACOM1000 is very hard..
They will have heavy QRM s9+  I guess
It is like EME working DX-peditions  the path attenuation must be about the same and the QRM does the rest.
after some hours of trying I finally  conclude   it is a mission impossible  for my humble station.
And I better just keep sleeping next time.


K1N 1826.3 heard well max 529 or so not strong enough to copy me
no clear greyline peak  best time 05UTC 05:30 here
some recording

K1N  T-shirts  in 2 versions now  you choose the one that fits best!

Received from mini in the box   a HDMI to VGA converter 
finally i can connect the Raspberry Pi  to VGA type monitors that are available a lot
Not having to connect it to the TV screen HDMI
The Raspberry pi needs many powerup's to get it booting.
i did de Linix  upgrade command
sudo apt-get update
sudo apt-get upgrade
updating this tiny PC  took about 1 hour about 400 list items where upgraded


(This text is still altered  by the HTML i have pasted before, can't help the html code is sticky)


The converter 6€ it is brandless... the Raspberry on the screen nice to have it back to play with.
The HDMI only is not a good option for hobby projects.

Connecting a USB-Wifi modem and could browse the internet 
with Midori 0.4.3  seach machine DuckDuck go
typical the humor of the Linuxians ..
Surprising  that it worked right away 
(but little later access was broken ..)

Ha Jaap,

Ja die K1N dat is me wat. Op 10m en 20m gewerkt. Op 30m zijn ze 's ochtend pas als ik al in de auto naar mijn werk zit of zitten ze in Shitty te werken.
Op 20m-12m gebruik ik de R5 die 3m boven de grond staat. Nog een wonder dat het op 20m ging. Op 12m vaak gehoord maar met die idiote split moet je puur geluk hebben of met 10kW ver boven het maaiveld uitsteken ...

Ze lijken wel wraak te willen nemen op EP6T die veel US amateurs heeft gefrusteerd (maar daar konden ze niets aan doen tgv extreem hoog ruis niveau).

K5D was destijds een stuk makkelijker te werken.

2011-01-22 DIAMOND 2m 70cm 1m30 Colinear inside

Having relative poor signals on the local 70cm / 2m channels using this X50 Diamond collinear 70/2  1m antenna at a height of 25m. I needed to investigate what could be wrong. Measuring the cable only 3W is left for the antenna of the 10W 435MHz output from a IC451E The cable is 30m type H100 Z50 10mm outside diameter it is semi air-spaced but has an impossible 4mm² solid CU inner conductor not much air left. I preferred the H43 Z75 cable having lower loss and mechanical better ratio in conductor size. My antenna uses SO239 connector UHF type semi air spaced isolator.  3W should be enough for a comfortable noise free FM signal. But only 27km away at PA0A the signal is weak too weak something must be wrong? I made a simple reference dipole of 2x17cm CU wire. With this dipole the signals where totally worse. So the Diamond does work? I got curious to look inside. Maybe moisture penetration degraded the antenna. This  antenna is rainwater close in its n...

SPF5189z Low noise preamp 23cm

 14-4-2018 updated Above the low noise  preamp 50 - 4GHz    ebay  6€ Tested  2 small porto antennas 1 Baofeng UV antenna left   2nd best signal on PI2NOS 2 eBay DIAMONDSRH805S  wide band 144/432/1200  it works for its size as expected 3 piece of wire :   best signal in the setup... Unit under test at workbench. It was stable  50mA  at 5V   few days,  but sudden the current went up to 100mA And i could  no longer adjust it with the negative bias Voltage. The - Voltage went to zero and the SPF input port became low Z. This SPF5189z was broken  no oscillations, no input overload just it broke while i was receiving the PI2NOS 430.125 using a small antenna at the workbench. The specs of  SPF5189z  say it has an internal circuit  regulating the bias current. Replaced . again   with an other of the 5 spare SPF i have. The new one again could be adjuste...

TS790 cat interface

A CAT interface  for the old TS790 144/432/1292 tranceiver to work with N1MM  including the internal CW keyer DTR and "PTT" RTS and WSJT MSHV with "PTT" control Using the 3€ FTDI USB serial interface picture bottom page first i bought the Kenwood USB serial interface cable that cable has the TS790 special 6 pin DIN plug this interface works well ...as long as you cut the 4-5  wire bridge on the ACC din.. with the wire bridge it did go offline after 30 seconds or so  Kenwood interface cable with CH330 eBay 15€    This type Kenwood interface cable uses a tiny 6 pin USB CH330 chip  The driver is CH340 known for Arduino it workes in W7/10 64  It has only TX RX Usart function no DTR RTS available  The TS790 settings are 4800b 8bit data 2 stop  default  N1MM does not list the TS790 it has the TS890  but that one does not support modes the TS2000 does support freq and modes and let you switch 2/70/23 it seem...
