CQWWCW huge CW activity 160 - 10m bands

 


 Started  LP but  switched  to HP needed some heating anyway sitting at the radio K3 + ACOM1000  .  Weather in the weekend too nasty to be outside.

Mostly looking for outside my zone, 3 point QSO's  no planning for 100% score but during the test i became more and more fanatic fired by the interesting DX workable even on 10.

 Had very nice long run USA VE  Sunday afternoon 15 and 20  until 20 became quiet.

That was my longest N.A.  run ever, with very good signals  astonished  by the endless  callers from Zone 3 4 5

All zones except 19 and 34 could be worked.

For a higher score I should have  spend more time at 40 and 80 and collect more cty multies.

But even then i would probably not reach the EU top 50 , So i spend nice  time on 10 for goodies

E2E E2A heard well at 10 but even with high power not copied  deja vue too high noise  i guess. VK3DX loud   no ZL on 10  But today Tuesday morning ZL3OY was -3 in 10m FT8 , would have been a good copy in CW. ultime DX for us.  Sunday 10 propagation was better then Saturday.

 Also  thinking what always happens Sunday evening to the end of the contest at 80.
 3B8M(4 bands)  9G5FI (6 bands wkd) or other  DX  multipliers will be at 80 with good signals
Pulling a huge pile of EU callers not allowing anyone the simple exchange to get into the log. Endless tale calling over the running QSO  in fact jamming until the suspect is forced to QRT. Have seen this behaviour in  the previous years with Asia or Africa DX  last chance to work EU.One should never comment that only makes thing worse.
Thinking of  this and being fatigue decided me better to take an early rest and stop with a good feeling about the contest result.

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...
