CQ 160 test and VHF 3band 70MHz SWR okay


poor propagation    X2 flare yesterday evening

only NA/VE heard  and QSO
VY2ZM   and K1LZ

HK0NA  redelijk copy     maar   no  ears for EU
in our SR ..

But finaly in the log of

20120128 0654   1834,9 CW   PA0O         599  CE1/K7CA        599                  
yes I was heard this time.


20120128 0826   7006,1 CW   PA0O         599  VP6T            599                  
20120128 0836  18132,0 USB  PA0O          59  TN2T             59                  
20120128 0840  24898,0 CW   PA0O         559  VK2GWK          499 Henk              



Na wat email contact met Martin DK7ZB  ivm  hoge SWR


Vrijdagmiddag even met wat zon even de mast omlaag en een nieuw mantelstroom filter /balun gemaakt.


Dwz  ca 60cm 50Ohm grijs 6.2mm  goede kwaliteit Coax  gebruikt ipv de 75Ohm H125    was ook nog soepeler kon nu 4 slagen door de ringkern cq 400uH is dat


En nu is de SWR  zeer goed! op 70MHz en ook op 6M en 2M
bingo! dat was het probleem  De element lengtes waren goed
Behalve misschien de dipool voor 6M daar zit de kabel op  die zou 1 cm te lang zijn omdat de lengte top-top gemeten wordt altijd volgens Martin ZB.  Er is een luchtspleet van 1cm dus 1 cm te lang.
Ik heb alle elementen zo gelaten.  6M  heeft nu een beetje oplopende SWR  boven de 51MHz     dat was met de 75ohm  balun juist aflopend zoveel effect had dat stukje 75ohm .
De cabel is 30m H2000  naar boven.


Tevens heb ik nog een geïsoleerde houder dwars op de drager van de 3Band Mini yagi gezet om de 160m verticaal vrij te houden van de beam bij draaien van de antenne dat werkt prima.
Ik had geen SWR variaties meer op 160m  bij het verdaaien van de VHF antenne waar deze verticaal dwars doorhien loopt.
Gewoon een kort stukje 3/4 PVC  dat met  de mast meedraait. zelfs antenne noord gaf geen probleem.
Het ei van Columbus!


WSPR 70.028600 MHz  OZ7IT  good copy
en PA0TBR  good copy   2-way WSPR



Now Flex1500   settings in PowerSDR
USB conservative  ruler maximum left
process piority high  seems the best setting here with the Dell D420 notebook W7pro32

hoop dat de ruis-crash over is!

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...
