23cm transverter vervolg

ADF4351 PLL signal 1296.100MHz    RX seems okay and sensitive
Maar Tx problem  MSA0885 oscilleert  1.5W out
wacht op een INA10386 MMIC 


DB6NT classic 23cm 1994 design  NE325 Rx    Tx M67715 1.5W 
 ADF PLL op intern 10MHz gelocked
handig zo'n signaal generator.
testsignal  1296.1MHz  picked up at the DB6NT RX

ADF4351  PLL 35- 4400 MHz  internal / external 10MHz reference jumper
Internal locked is not very stable it drifts and hand effect.  External reference needs a clean strong signal.  My GPSDO Trimble Thunderbold GPSDO 10MHz output is not direct suitable. An active 10MHz bandfilter interface is needed. 

De DB6NT 1.3GHz transverter classic 1994  is lang niet eenvoudig te bouwen
kost veel tijd  zo ging dat vroeger dus.
Een veel moderner ontwerp voor 23cm is van SG Lab LZ5HP V2.3 ano2016 design
http://www.sg-lab.com/TR1300/tr1300.html
 is  compleet gebouwd   heeft meer opties voor de local oscillator
met externe 10MHz referentie ingang.

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...
