First night:
Friday evening the gusty wind  finally calmed down a bit and I managed to tilt the mast up.
The wind was turned to N-E . Some hail and wet snow showers  made it a cold job.
Also the K9AY was re-erected. No damage  only the rotator turned very slow now for unknown reason no things visible jamming it.
The multi band wire dipole 40/30/12 became spaghetti.  No way to unravel  in the dark.
Wire antenna's will struck to anything that touches it.

But I was ready for ARRL160
I entered L.P. single 
3.1. Single Operator (use of spotting networks is NOT PERMITTED):
3.1.1. QRP (5 watts or less)
3.1.2. Low Power (150 watts or less)
3.1.3. High Power (1500 watts or less or your country's maximum power limit

It cost me a few dB the K3 KPA3 output sometimes drops to 80W my old tube FT102 could get 150W out.  The KPA3 should be able to give 120W out.
And  not using spots / dx cluster  I like to see what's going on.
It does not really help the cluster spots  since I can only work the stronger ones having a receive antenna for EU.
After the first night 40 QSO S & P  1 QSO only on CQ.
Some good signals  W4 W5 K0HA  NE could be heard only.
No  7 or 6   propagation not to good.

64 QSO final

The strongest VY2ZM huge even on the loop S9.

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…
