PA0O ham radio

For WSPR at 137kHz to filter out the DCF39 signal at 0.1388kHz I make use of the CW 500Hz filter in my IC706. Receiving(only) with the IC706 in position CW-narrow using the 500Hz CW filter is possible settings: IC706 Dial:   0.137500  mode CW-R  (for USB this must be 0.13600 to bring the audio in the center of USB filter) WSPR: Advanced : Rx BFO (Hz) 570 (in my case) to adjust the audio at the correct frequency in the band.  (1500 by default for USB mode)  WSPR Dial: 0.137000  Brings the displayed frequency ruler  400-600  meaning 0.137400---0.137600   Tx  0.137500  (no TX Txfr =0)   Decoding is good  decoding traces as low as -31db But   i have a problem that i could not fix yet: The reported frequency is consequent 72Hz to high for all signs. The trace position and frequency at the scree...

My first ever 137kHz  HAM signal  G8IMR  -23dB    on the IC706 USB + preamp.  I listened  only 15 minutes on 137 it became too late already again  glad that it worked  i saw 3 traces of G8IMR    it decoded 2 times. The tracking screen was relative clean although the DCF39 was still s9 in the USB filter  of the IC706. There where some weak thin lines drifting  and clearly distinctable the frequency stable and exact timed  trace of G8IMR. Last night I finished my preamp http://ea4eoz.ure.es/lfpream.html     thanks Miguel  A. Vallejo, EA4EOZ Although  it is a simple thing it took me 2 evenings  to build and get it working. Needs a small  modification for use with a 50 Ohm signal source  like my K9AY antenna.  It did not work  with the high impedance C 33p  input antenna...

This phone is the absolute top in user unfriendliness It abuses you with  its prototype software It will rarely connect to any WLAN access point. After entering the whole connection data it tells you it fails and you can try it again if you want.... nooooooooo! Using blue-tooth it is possible to get your pictures out but it is a quest to do it. The display is a billboard  everything is clear except that what you need  to see. It can not be used ( in daylight)  or never... One positive thing is that it can run I-GO.  Running I-go will always need an external power supply. Technically it has all the hardware to be a good smart phone  but   smart software is needed.. Luckily   i did not buy the OMNIA  just got it for use. Today I got the HTC Desire It was not possible to synchronise the phone data to Outlook since it just will not connect. Even a copy of  2  new ...

In an attempt to make more use of  the WSPR propagation data. I  try to calculate a  "DX Index"  the  DXI  for JO33HG  A simple calculation to start with: I take 100 WSPR spots of the last 12 hour period. Ordered by DX ascending.      calculated for my location. Unique calls checked    excluding repeating  spots Unique calls check can not be used with multyband. The number count of DX >5000km  is the "DXI"   for  my location: 26 December  morning  the DXI was 40       for bands 500/160/80 26 December  evening        DXI was 54       including 10/15/20/40 27 December  morning 06UTC    the DXI has dropped to  10! It is a start and gives some indication. But it can use improvement by ...

Purchased an Dell Optiplex GX620  P4 3.2GHz HT  75GB HD  small quiet PC  occasion for 99€. Has the trusty XP  OS  so i hope to got rid of the communication hangers with the USB-serial i have with W7pro 64b  and N1MM  Also i wanted to have a WSPR N1MM dedicated PC in the shack. This one is RF(almost) and audio-wise quiet and has low power consumption for 24x7x365 purpose. I gave up W7pro-64 with N1MM and USB-serial converter it is not stable i have to reset the interface too often it is meshing up my logging and it is a nerving me.. Until now no hangups it is quiet almost forgot it is running on the desktop. In the same shop i purchased an Eminent Em4570 router  to replace the  RF  noisy Linksys WRT54G with its build in 2 step-down very noisy switchers i could not silence the RFI in 14-30 MHz band. This Eminent seems to be of higher quality  it has ...
