WSPR 500kHz (too) many frequencies to watch

I might need some other receiving techniques.
Last night  WD2XSH/6  EM31js  was received strong  by G8HUH  IO81MG
I was hopping all night 510.000 kHz   for WE2XGR/6   
 and  499.600 kHz  for WD2XSH/17  (USB dial setting)  (
+160 and 80)

But  WD2XSH/6  was on  495.983 kHz  that means I had to set my dial 1500 lower  to 494.500 kHz  to receive him
And possible  WD2XSH/17  did move here too??
I would like to receive  them all ...
Now i have WSPR set 600= 499.600    other = 510.000

To have more hopping frequencies  some not used bands like   7 or 14 MHz  could be set to other 500Khz bands..

This is my short list of  current WSPR 500kHz bands:

Dial:      502.400      used in EU  
Dial:      499.600      WD2XSH/17   i used to receive him here
Dial:      510.000      WE2XGR/6     and other WE2XGR/?
Dial:      494.500      WD2XSH/6     and  /17 new freq?
Dial:      503.630      DI2AF
and possible more "private" frequencies in use
 pity that i did not know this  the propagation on 600m was good

Received WE2GXR/6   at 08:20   very late  in broad daylight  almost half past 9 local time!
Never had a decode that late.

A pity that one of the major advantages of WSPR using one standard freq 200Hz band is lost at 500kHz.

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...
