Thanks for the QSO with my station !
My 5 elements monobande 15m, a dual-driven HB9CV plus three directors is down for maintenance.
I spent a lot of time to renew a second-hand 11 elements Log-Yagi 5 bands Hy-Gain TH11DX and now test it on the air since July 2015.
The antenna in the field before to be renew. Three boom parts were neccessary to fix them alone on the mast tube of the 21 meters tilted crank-up tower from De Kerf. My model is a renforced 3*8m in aluminium, 150 kg weight load and 2 sq.m antenna wind load @ 160 kmh.
There is no so simple than a Hy-Gain trap. Aluminium flexible wire for the coil and a capacitive tube, with R parallel which is about 140.000 ohms. That is not excellent but not bad too, compare with others commercial traps...
But traps could be easily improved against invaders, corrosion and bad mechanical/electrical contacts.
The screws of the coil extremities both play as mechanical and electrical contact. This is not good and source of problems. Put an other screw at 90° to fix any mechanical stress. Use conductive grease. Increase isolation between wires with plumber teflon tape.
Prevent corrosion with ruber tape around coil and screws.
Then paint the antenna in green - so neighboroughs could not complaint - and do not forget to fix a mosquito repellent fabric to prevent insects inside the traps without close the holes for discharging the condensation water. ...
That's take some days but as it is a pleasure.... I underestimate the time to do that because of the six traps, the eleven elements and screws, nuts, bolts, lockwashers to clean, check, grease, and so... Looks the phased line for the Log-cell radiators. But I now put it on the tower and the winter can come... I am ready to be again on the air !
Also I test some Innovantennas monobanders stacks of 6 elements on 10m and 15m, 5 elements on 20 meters. On the 40m & 80 meters bands, antennas are verticals, dipoles, parasitic slopers arrays system. The 160m antenna is 3 wires folded 20m+20m inverted L. Low bands receiving antennas are different loops & beverages configuration. The antennas system often changes with dxpeditions or contest/operator class.
I also try to optimize the towers sites and the heights of the antennas in accordance with the profile of my land, using for that the ARRL HFTA and Eznec softwares. Read also the K6TU propagation website for the data of your land. This is a real goal for this recent location to find the best choice of antenna type + tower site + antenna height + antenna beaming + expected coverage area ! Surprising simulation results and confirmations in the real life with good signals reports from hams or from Reverse Beacon are frequent and encourage me to continue to explore this approach.
I like VOACAP website (by Jari Perkiömäki, OH6BG/OG6G), a fantastic propagation tools for amateur radio !
F6GOX is my first amateur radio callsign as a CW and phone operator CEPT-HAREC Class1, since 1980. I was 21.
Then I had used many calls as 4U60UO, FE6GOX, FJ5BL, FJ0A, FS9TI, HW6GOX, TK5BL, TM5T (15/06/2013 to 14/07/2014), TO6GOX.
Also in some IOTA dxpeditions as TK5BL on EU-164, TK0KP on EU-104, FJ0A on NA-146, FS9TI on NA-199.
I participate since many years in contests activities.
As the former president of the ARP Radio-Club de Paris between 2005 to 2013, I have organized many activities for F6KVP.
I now am active most of the time from my QTH in Dordogne (DDFM 24).
My amateur radio activities - portable - from downtown Paris are scare but look for me time to time...
My all bands DXCC is 321 mixed, 296 CW et 305 Phone.
I also collect vintage French qsl cards, main land (F0 to F9 series), overseas territories and colonies (FA to FZ). I would very appreciate that you contact me in case of you want to give or to sell me your vintage French cards.
Do you want my QSL card ?
With GlobalQSL system I send you a special homebrew paper printed QSL for each regular, contest or portable activities. I like take pictures and create QSL cards with this tool ! (Right-click to enlarge pictures)
QSL route :
1/ You are member of an IARU QSL buro :
=> You just have to send me a QSL request via my email. My qsl card will be directly sent by the GlobalQSL system to your qsl buro.
2/ You are not member of an IARU QSL buro or you prefer quickly receive a direct QSL card :
=> Send me your card with SASE and GS/IRC
All QSL directly received are answered at the 07/06/2015.
3/ You want to send me your QSL card via buro or via GlobalQSL :
=> via F6KVP QSL manager
4/ Are F6GOX or my others activities on LoTW ?
Yes, all my logs since 1980, included F6GOX, F6GOX/P and TM5T, are now to LoTW. What a nice tool ! I have refound QSO checked since many years by others hams, others qso losted in computer failure as I always keep my paper logs, others qso with never received QSL or losted QSL via buro or mail services! Take a safe decision for the others hams, put your log on LotW, it now never could be losted. This also is over 52.000 records of my amateur radio life...
If you are a visitor to Paris, do not hesitate to sent me an email, I will be very glad to meet you.
Best 73 Laurent F6GOX.
