Organizer:

Romanian Society of Radioamateurs–YO3KSR Club

Date:

March 19, 2012, 16.00-18.59 UTC

Bands/Mods:

80 m

CW – from 3510 to 3560 kHz;

SSB – from 3675 to 3775 kHz;

PSK31 – from 3580 to 3590 kHz

40 m

CW – from 7010 to 7035 kHz;

SSB –from 7090 to 7100 kHz, and from 7130 to7200 kHz;

PSK31 – from 7040 to 7045 kHz

Categories

Can be chosen one of these categories:

- A - QRP - (max.5 W PEP) single operator

- B - LPI - Low power - single operator (max.100 W PEP)

Note: equipment used at this category must be limited to maximum 100W PEP. If transmitter is capable of more than 100W PEP operator must reduce the power at maximum100WPEP

- C - LPG - Low power group – two or more operator (maximum 100 W PEP)

Note: equipment used at this category must be limited to maximum 100W PEP. If transmitter is capable of more than 100W PEP operator must reduce the power to maximum 100WPEP

- D - SWL - receiver (only category « MIXT »)

And one of these working modes:

-E – Mixt – any of two or more transmission modes

-F – Phone – SSB

-G – CW – Morse code

-H – Digi – PSK31

Reports:

- YO stations: RS(T) + serial number starting with 001 + 2 letters code (Bucharest district (a.k.a “sector”) code XA-XF for YO3 stations, or county code for YO counties).

Operators with YO3 prefix will give the report as follow XA-XF only if the transmitter is located in Bucharest XA-XF districts (a.k.a “sector”), if not will give the report accordingly with the county/country where is located the transmitter.

- Foreign stations (other than YO’s): RS(T) + serial number starting with 001 + 2 letters code (code= internet domain. E.g.: Russia=RU, Hungary=HU, Bulgaria=BG, Moldova=MD etc.).


Score

A. YO stations:

- 1 QSO YO3 - YO3, YO – YO, YO – Foreign= 2 pct.

- 1 QSO YO3 - YO, YO - YO3, YO3 – Foreign = 4 pct.

B. Foreign stations:

- 1 QSO with a YO operator or Foreign = 2 pct.

- 1 QSO with a YO3 = 4 pct. (only for transmitters that are located in Bucharest’s districts)

SWL: must log both call signs and both controls transmitted, maxim 5 consecutive QSO’s with the same call sing.

Multipliers: number of counties (AB, AG,... etc.) + number of country codes. (see Appendix) + number of different Bucharest districts YO3 (XA, XB, XC, XD, XE, XF)

Note:

Operators are entitle to work with any station once in CW, once is SSB and once in PSK31 according to band plan described above and multiplier will count only once in such cases. Also QSO’s logged in different bands with same station are scored with the same number of points

Final Score

Final Score = (summ of points of the two bands 80m and 40m) * (summ of multipliers of the two bands 80m and 40m).

Vasile Ciobanita, YO3APG - SK

Postez aici, cu intarziere, stirea care deja se cunoaste. Vasile Ciobanita, YO3APG nu mai este intre noi.
Astazi s-a dus sa se odihneasca.
Inainte insa de a se retrage definitiv, a facut ceea ce ii reusea de fiecare data: Ne-a strans din nou laolalta.
Am senzatia insa, ca azi a fost pentru ultima data!
In pofida celor care vedeau in el sursa tuturor relelor din radioamatorismul romanesc, m-am incapatanat sa vad un om care si-a pus o mare parte din energia sa (daca nu intreaga) in slujba radioamatorismului.
Am facut abstractie de sistemul in care evolua si am preferat sa il cunosc si sa il stimez ca om si mi-am permis sa il banuiesc de cele mai bune intentii.
Era peste tot, raspundea tuturor, stia o multime despre multe. Si nu numai despre radioamatori si radioamatorism.
Chiar si atunci cand avea o opinie diferita, discutia in contradictoriu era placuta si aveai la ce sa te gandesti.
Am fost criticat si eu si el pentru calitatea de "Membru de Onoare" al Societatii Romane a Radioamatorilor dar niciodata nu a vrut sa spuna cine anume il critica. Era discret si chiar si aceasta discretie i-a fost reprosata de multe ori.
Sunt multe de spus despre cum a influentat subtil drumul prin radioamatorism al multora si sunt destui care isi datoreaza o cariera lui Vasile. O vor face altii, sunt covins.
Viata e uneori aiurea si te lasa descoperit atunci cand te astepti mai putin.
Acum, Vasile ramane intre noi prin prin carti, inregistrari de QTC, cateva inregistrari video si multe, multe, tare multe amintiri raspandite in toate indicativele cu care s-a intersectat.

Cea mai puternica amintire a mea este cand, intr-unul din putinele momente de liniste, m-a tras deoparte si mi-a marturisit ca de abia asteapta sa se retraga pentru a mai face cateva legaturi caci ii lipsea tare mult asta!

PS.
Stiam de dragostea sa pentru munte si am descoperit ca nu numai radioamatorii l-au "avut" pe Vasile ci si montaniarzii! Clubul "Floarea de Colt"
este marcat de aceasta disparitie.

CODAN 9360

Today I get my Codan 9360...
I dreamed a lot at this radio, for the last 3 years, seems to be impossible to get one!
So, this is my X-Mas gift from my wife :-) Nice!

This unit is full 2-30 MHz TX capable, with front keypad programming mode.
This is somehow complicated because there are only 12 controls (10 keys and two opto) and the menu is very, very complicated!
Not only this, but the engineering is weird for a ham!
I think I will need the programming software to put the frequencies into the Eprom and also make ALE to work with HF-ALE ham radio network.

This is a small video I made when I was in QSO with YO2LGX and YO2LEO.

My "HELLO WORLD"

In these days seems that you cannot light a simple LED without a very complicated electronic hardware (microcontroller with some Quartz Crystal around it etc).
So, I started to become interested in these "chips" becuse I do not want to be so "obsolete"...
First, I started by searching a development board...
I soon received from a fellow ham a EasyPIC 2 Development Board fitted with everything you want.
After that, I stated to search for a suitable PIC to start with. A 16F877A seems to be the best for a beginner because has A/D converters and a lot of I/O ports.
The interest in PIC was determined by the need for some repeater automation, including battery management.
After a lot of struggling, I manage to read and write the PIC using the onboard USB programmer. This was by far the most time consuming phase (a few weekes of study). Don't laugh! I have no one to help me but some internet related posts!
To make the long short, after a successfull R/W operation, I manage to blink a LED but this don't count as a "Hellor World" project because was made with a downloaded .hex file!
I read (and trying to understand) various things about uC.
I soon found that I need a Programming tool and a compiler.
Everyone pointed me to MikroE solutions: MikroBasic and MikroC. Also I read Mr's Surducan book about microcontrollers and JAL (Just Another Language) as reccomended by some uC specialist.
After a lot of reading (and sometime "lot-of-no-understandings") I stayed on BASIC.
This is my first, true, "Hello World" project:

This program is intended to be used with a 16F877A Microchip PIC,
a 10 MHz crystal and a 4 digit, 7 segment LED display.
It count from 0 to 9 but the number is displayd alternatively from left to right.
As I cannot attach the .hex file, use Copy/Paste and a txt editor to make your own hex file
to upload into the uC:
