Rebuild 9Q1EK station
- September 25, 2012: 2m Preamplifier and QRO coaxial relays in a RF box, done !
For 2m operation ; Parts used:
- Connector XLR male (control from TX/RX sequencer)
I know ! coax relays, connectors, etc... are expensive, but ! the project was able to withstand the power in the futur (above 2,5 kw) and have sufficient insulation vs frequency to protect the preamp.
Next step will be: same RF switch box for 70cm, 23cm and separate three bands RX/TX sequencer.
September 14, 2012: All options are installed.
( 2 x DSP UT106; Filters FL-132/FL-133 ; Crystal CR-293; UX-910) and small adjustment of the sensitivity on the three band. (see W6PQL IC-910H tweaks).
More development later...

Despite I sent a couple of SOS through couple of Ham web site, no answer !
I had more answers when my station was on air when I sent CQ for Pile up !!
After a long traumatism, (mental and financial) I am under way to build and to try to put 9Q land in EME (nothing of foreseen from 1,8 to 50 mhz, No HF equipments), Articles very soon on the developments for 144 - 432- 1296.

Labels of wine in Morse Code
While surfing on the net, I saw this:... Original for Ham Radio world, isn’t it!
Wines from Australia
“Henry’s Drive wines are branded along a postal theme. The Morse Code range pays homage to the first electronic mail system. The variety of each wine is printed on the label in Morse Code.”
2009 Morse Code Shiraz
“Henry’s Drive wines say: “In this digital world, we remember the craft of the postal telegraphists. For decades their Morse signals, dexterously delivered across Australia's great telegraph line, connected us with the world and helped to save countless lives. We honour the Morse Codian Fraternity with this collection of fine wines”.
Even for a good telegraphist… Has use with moderation.. Thanks “Henry’s Drive wines”

Histoire de Sequenceur
Par la suite, pour les commandes de commutation Préampli, antennes en VHF et UHF, je me suis inspiré d'un schéma fort simple et sans réglage de F1HRU.
Ici le lien, schémas, circuits: http://www.f6kuq.org/f1hru/sequ.htm
Je n'ai pas pu reproduire le schéma exact proposé, mais cela fonctionne ..!
Il sera intégré dans le boitier de relayage du préampli et relais coaxiaux avec 3 relais coax au lieu de 4..mieux, mais plus cher !
