K5P zzzzzzzzz

5259kHz Heard ZS6EZ  and ZS4TX  good signal in CW
had to be split I txed at 5359 +100kHz  seemed a logic choice but no QSO
I can only receive DX  lately

VP8STI   was relative easy to work at 30 40 and 80 yesterday night not strong huge pile
 fb operator, good operators do not attract that much lids
Heard very weak at 160m  had to QRT 01:30 to late for me

K5P  has been a waste of time and disappointing experience.
Is it the Chinese Radar ?

Now added 30m   to  dipole 30 60 80m good matching on 3 bands

1700Z prime time grey line   80m  Palmyra  K5P  (KH5)
but  silence
They where not allowed to stay on the island at night.. that means almost no window to EU for low bands.  Birds rules like we have in our wad coast area nothing is allowed.

propagation was not bad at all   aurora reported a good chance for Aurora enhanced propagation
as thats been observed at 80 and 160  many times during or after Auroral disturbance at SS

20160120 1710   3507.5 CW   PA0O         599  XW4ZW           599                
20160120 1726   3502.1 CW   PA0O         549  ZL2AGY          579 Tony              

With all the D-QRM a pile up to EU not a pleasure
As soon as K5P is spotted or already before cops and D-QRM  make copy of the weak signals
almost impossible.
And why calling for specific zone JA at the wrong time. Why not just calling for any? if the knowledge of propagation is poor?

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...
