Zender DCF39 Magdeburg hoe lang nog?

Gisteren Donderdag  Beverage antenne weer uitgerold na overleg met de boeren hier  ca 300m draad richting Oost de West Beverage Vrijdag zo juist terug uit het kletsnatte veld. Ik test de Beverage op DCF39 ze werkte na reparatie van draadbreuk en aantal slechte contacten weer oké , Dan moet DCF39 ruim 9+40 boven ruisniveau zijn. Ik ontvang DCF39  op meer frequenties.

Ik dacht  IMD in de externe preamp CA3130 ,maar ook op de IC7100 zijn  ook die 2 draaggolven

Ja de IC7100 is echt een buitengewone Tranceiver  van lange golf tot UHF 70cm 

Burg 50kW 138.9kHz 9+30  Beverage direct op de IC7100 met pream2 in

Mainfingen 100kW bij Frankfurt 129.1kHz is S9+20 Beverage direct op de IC7100 preamp2 in

Mainfingen heeft 1 draaggolf Burg heeft er 2 waarom zou dat zijn ?

De vraag is hoelang nog deze zenders in de huidige energie crisis 50kW rf? dat is zeker 100kW DC tenzij dit een hoog rendement  class E generator is wat ik wel vermoed maar dan toch met alles er omheen 60 kW DC

 



Schermfoto  Flex1500 met 136kHz bandfilter op beverage  2 draaggolven met telemetrie modulatie  , voor wie bedoeld? 135.6kHz  en 138.6 kHz  daartussen ! precies de 2200m amateur band met het WSPR venster de grijze balk . Uitgerekend is "onze" 2200 vlak bij de sterkste zender in Europa en de Wereld?  dat maakt het decoderen van zwakke amateur signalen wel een uitdaging maar uiteindelijk verliezen we zeker 10dB ontvangst gevoeligheid hierdoor.

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...
