Super tropo 144MHz . Who or what is LQ0HGF ??

Yesterday very good tropo 144MHz  and 432
copied short time 144.174 MHz  FT8 mode EA1FCH and EA1TP
 EA1 was only short and weak here in wind an rain !

I still have  8W out from the K3 XVTR  not yet finished the PA...
Could make 2 way EI3KD and EI19RE both IO51   over 900km with 8W not so bad
GW7SMW 2-way  heard     G7RAU IN79 900k+

OY6BEC was reported in EA1  little over 2000km !
and saw G7RAU working EA8 !
nothing here  we where a little to north

-----------------------------------------------------------------------------------------
Mistery decodes   WSPR HF and MW
LQ0HGF in RP22  fantasy call and locator..
i have seen LQ0HGF in RP22 many times reported at 474.2 kHz
  it can not be explained as random noise caused decode
I thought there are only 3 or 4 reporters of LQ0HGF at 474.2 kHz 
DK7FC F59706   and  "KPH" they must have something in common
But  the query  all band unique showed the issue is broader then 474.2 kHz
W4HOD  46306  decodes at 20m !!

Mean time a 2 weeks check on LQ0HGF showed that he number of decodes has been reduced a lot 
"Only" 6 spotters left but still over 400 spots      
  i bet those spotter use JTDX software

thanks for reply
this must be a software issue in JTDX decoder?
It is not WSJTx what is used by the majority

Unknown said…
The decodes by N4WLO and N4WLO/2 were using WSJT-X v2.0.0

In the last week I have noticed some occur when the receive is switched off.

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 adjusted at 50mA  5V 
The current raises to 150mA  when removing the  negative gate voltage.
Where is that internal bias circuit ?
I suspect  eBay …

2011-01-22 DIAMOND X30 2m 70cm 1m30 Colinear inside

Having relative poor signals on the local 70cm / 2m channels using this Diamond collinear 70/2 combi 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 but it is no longer selling i think. This H43
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 normal vertical mounting position. But take care if your mast can b…
