Top tropo 6M ES

Finally summer inversions are here
one day 33/34 to warm C next day 19C..... to cool ..
Very dry season again no rain.
Friday 28 June  Saturday 29 June
Very special tropo  path over land, first time ever to hear 1296.855 EA2TZ IN93BF  1278km
2 mornings around 11 seems to be the best time, in a row copied weak with QSB but Q5 1296.855 MHz tropo
But i did not catch a human EA no matter my advertising at KST2ME or cluster
Wrong timing  i feel this could be the rare unique occasion .
Possible for the EA1/2 it is normal  DX to G over water path but over land it is rare.

The 1296 MHz XVTR is direct behind the dish
30W and SKY67151 preamp
The i.f.  146 -148 MHz IC706  146.8850 # 1296.8850

A 2way with Guy F2CP at almost the same DX 1248km IN93GJ was in CW and USB
2 beacons  at 23cm not bad EA2TZ 1278km and ES0SHF 1141km

But 144.174   EA2XR FT8 a 2-way

Earlier besides the 3 LA beacons booming  in and a lot of radar signals

Beacons not heard before
longtime S9 heard
Callsign: SK1UHG - JO97CJ
Frequency: 1296.9510 MHz      note Beaconspot freq 1296.9500 is not correct

And  ES0SHF Estonia S3 max  about 15 minutes copied
"fast" CW ID 20 wpm and carier
Callsign: ES0SHF - KO18DN
Frequency: 1296.9150 MHz  but spot frequency  1296908
Date Last Spot: 2019-06-29

QTF: 90 and 270

also new for me OK0EKL - JO60LJ64   no OK heard

6m ES FT8

6m was a bit open to Asia but only for ham's a little few hundred km S-E
In evening short opening to USA just weak here heard some W from FN again

Last night 6M FT8 JW7QIA  in JQ69  sudden +13 few TX periods working LA SM OH  then faded for ever
later some thin sigs from N-A heard K1TOL  VE2DLC K2ZD
This Sunday morning  few JA heard JA7QVI JP7EIP in the FT8 log
several other JA heard  1 or 2 decodes
070645 -10 0.2 1815 ~ PA0O JA7GYP -03
070545 -9 0.3 2846  CQ DX JA7QVI QM08 Japan

070700 Tx 1006 ~ JA7GYP PA0O R-10
heard F4FUF working VK4MA
I still wait to catch VK8AW or VK4AM once but   think i need to move south to hear VK again after 30 years at 6m
This years 4m opening to UN  i saw the rest of PA extensive reporting the 2 UN hams
but here only 1x decoded it is time to find an other hobby or move to EA CT

What a big difference there is between JO33hg and a little more south JO21 JOx1 fields
it looks like antenna's malfunction.

Also the Solar Edge SE6k of the neighbors  50m north of me does not help.
My once low noise QTH is screwed up by this Solar Edge QRM machine
 producing constant noise and digi trash between 1 - 160 MHz !
During daylight time for over 3 year now.
Last year our Communication Agency A.T. did check on site and found that this SE6k Solar Edge does not comply with the EMC rules.
Never the less it is not replaced i am still waiting.
Now i think i also  do not have to comply to our rules?

Huge difference between JO33hg and JO21 has always been at 6m 10m 2m 4m
For instance this Sunday and Monday night several hours USA is worked in south-west PA DL G
Nothing here but 1 W seen, worked before only 1 decode.
Occasional signals in JO33hg W/VE , only a fraction of what is possible in JO21 JO31 or JO32 100 to  200km south.
And if we do have W VE then  DL OK OE I SV LZ have far better better signals and is better DX.
I also would prefer DX from EN or DN over FN.

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…

Nice opening10m and 12m to S.A.
