mooie opsteker in barre tijden

PACC 2013 was weer een  succes met de dipolen  3x op rij 1e plek in CW low power.


Aluminium buizen voor  de nieuw  te maken 6/4m antenne   gisteren besteld  en vandaag al bezorgd!
Haast niets  staat me nu nog in de weg om de oude LFA 6m beam om te bouwen naar een  YU7EF  duoband 6/4 m  van Pop

Toch maar een grotere antenne proberen te maken.
 Ondanks of juist dankzij  teleurstellende propagatie en het voorjaar dat gelijk is aan een koel najaar.
De propagatie op 10m  is  iets hersteld.
Een paar dagen geleden hoorde ik PJ4NX nog op 50.105 in CW 529

Toen ik de 6m beam van de vliering haalde na 2 jaar. Zag ik iets bewegen  een kitten
Ongemerkt jonge poesjes in huis en de Steenmarter familie lijkt vertrokken dat is goed nieuws.

 voorjaar 2013 typerende luchten temp 10-15C   heel af en toe een dag met zon
de verwachting is een kleine ijstijd.
De bomen staan wel mooi in bloei

Gefeliciteerd Jaap, toch knap stukje werk voor de 3e keer 1e worden. Katten kun je beter hebben dan steen marters denk ik! Succes met het bouwen van de combi antenne. 73, Bas

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...
