The first spring weekend at OL7M - not only BBQ 

   The spring is there! It was snowing a month ago but we hope that it was for the last time :) We decided to cut the grass and clean the QTH. One beehive added and ram BBQ was fantastic :)

Olda OK1YM received the plaque from CQ WW CW 2013, congrats! He run 80m SO as OL7M. It looks that our 80m antennas work but why don't have more gain? :)

Our old tractor protested after the winter season...

Good ground system is one way how to enlarge the gain of the sloper system. There is 2500m of wire in more than 120 radials. Nice work during sunny day! 

CQ WPX SSB 2015 as OL9A SOSB20(A)

   This was my first time single op on 20m band. It was not my favorite band but now I am looking forward to run again :) We were thinking about Multi/Multi but did not find enough operators. Than Standa OK1CID run 15m SOSB(A) as OL7M and I 20m SOSB(A) as OL9A.

   Standa donated 2el HB9CV for 15 and 20 so we spent Friday on the tower to get it ready with new Stack Match II. by our RemoteQTH.com. Finally all works :)

        antenna measuring in 18m :)

becoming crazy

   And what about the contest... I didn't have any experience with 20m so it all were suprise for me! Band was open from 0 UTC and I was late abt 25min. There were nice signals from NA and I have never heard so many times : booming, very strong :) Nice start, isn't it? Another nice thing, LP to VK and ZL. Totaly 40 x VK and 10 x ZL worked, most via LP. The highlight? For sure Dave VK2BSY with his "walking mobile!". Really nice signal Dave via LP! Another ones: 13 x  KL7, 6 x KH6, Victor E51USA, FO8AA, H4 and a lot of mobiles not only from USA. Worked  1000 x USA and 100 x VE. But where there are JA stations???

   Anyway all worked fine and new small HB9CV to SA and AF dir helped to catch some PY ane LU in the QRM.

The final score:

mcHF - my new toy, part I.

    What is mcHF? It is really nice HF SDR TRX. Yes, SDR but you do NOT need PC :) Have a look at home web by Chris M0NKA. Chris provides PCBs and LCD with very quick shipping. There are my ones :)

There is the block diagram:

   

And more pictures in Chris' gallery.

Playing with new HW

   There are some new projects. First one is 6-to-6 interlock system for 6 to 6 switching. This is main "brain" of it. Optocouplers at inputs, relays at outputs. Each TRX will have controller with PTT and HOT switch protection. You can control it with simply rotary switch or push buttons or CAT.

   Another ones are 6-to-1 switch controller and stack match controller. First one allows you to control 6-to-1 antenna switch, basicly with push buttons but also with CAT or Ethernet (IP version).

    Stack match controller could be use as multibeaming controller (with small hand box) or antennas stack - 1/2/3 + BiP, BoP etc. Again web controll as the option. Included hot switch protection and PTT sequencing...

 

   There is our Open interface and we would like to work at version 2. With some new features as PTT interlock input, AF MOD way switching, RTTY TX text decoder etc... (Thanks Goody K3NG for help!)

ARRL DX CW 2015 - nice M/M action

   What a nice contest! This was nice Multi-Multi action after a year. Really nice to meet old and new friends. We lost a little bit on 160m and 10m maybe thanks our mistake with missing CQ in F1 message. Skimmers did not spot us as the others :( Anyway we did have really nice time and not only contesting is important!

Thanks a lot for nice battle with IR1Y friends on CqContest.ru and congratulation guys!

CQ WPX RTTY 2015 - SOSB 80HP

  There is CQ WPX RTTY contest again! I was disappointed by the participation at 80m last year. My dream 1k QSOs was really away. It was little bit better in 2015.

   We met together with Pavel OK1MU on Thursday and started preparing the QTH. We do have new HP PCs and I hope to get ready the station in the better time :)

  Pavel operated as OK6W in SOSB 40m and I on 80m. The propagation looked good but participation was really low :(
