Fritz dostal vysílač

V noci 22. 6. byl odchycen německými kolegy také vhodný samec na lokalitě poblíž obce Nosswartling a vypuštěn zde se satelitní vysílačkou se jménem FRITZ.

Fritz, číslo vysílače 128725, kroužek H140985, Nosswartling, Bayern
Vypuštěn 23. 6. 2013

Lokace 25. 6. 2013
Hi Markus,
From ID 25 we received on 24th two good locations: Lc1 (19:23:08) 49.285 12.827 and Lc2 (20:07:48) 49.271 12.820. Both depicted on the map. Not clear where exactly the bird was situated or he moved meantime? Where he was caught and released? If not on map, try to send coordinates.
Unfortunately no data from ID 91 but also ID 24! If PTTs started in same time but a day later then your tag have been transmitting much earlier than expected.
All the best

 

     

Hi Markus,
Time of transmissions is expressed constantly in UTC=GMT (to avoid confusions throughout the year). Our summer CET is plus 2 hours! From the first two cycles of this PTT we can estimate next beginning as follows:
ID 128725:
Period ON+OFF: about 54 h
Last ON beginning estimated about: 24.6. 18:00
Beginning of next ON estimate: 27.6. 0:00 GMT
Our time ON beginning estimate: 27.6. 2:00 CET
(easy +- 1 or 2 hours...)

Two km error is what we expect.... you must try to find it with reduced GAIN in your receiver or using a rotating antenna to get more precise locations!!!


Time predictions are still imprecise. Later I will creat an excel for it. As simple tool, you can use also this graph - just copy and shift right the part (double periods) with red small triangles.
Keep in mind that it is in GMT! Best if you can detect the beginning of ON!
Better situation will be on 29.6.
Best regards
Lubomir

PS: You may complete xls (measurements) and other details of Chris?

Hello Lubomir,
Fritz is still sending. Today I started to check the signal at 4:00 clock and the signal was on and he is right now still sending.
Markus
Yes, I found that transmissions started about midnight (what I expected) and the best location is not far from place where it was caught.
Next is supposed on 29th about 8:40 (CET).
Lubomir
PS: Have you been able to locate more precisely its location today?
It was perfect, I found Fritz in the same meadow where I cought him. The receiver did his job very well.

Situace se signalem Fritze vzbuzovala u mne skutecne velke obavy.
Protoze data Fritze neprichazela a Markus mi napsal, ze 6. nemel nic, ale 8. naopak mel dobry signal, nedalo mi to a vcera v dobe zacatku ON jsem tam radsi zajel. Domnival jsem se, ze mame treba posledni sanci zachytit vysilani ze zbytku energie, pokud by se treba neco vazneho stalo. Situace byla lepsi, nez jsem predpokladal a uklidnila mne. Markus muze jednoduse z okna pracovny poslouchat signal Fritze a dela to poctive. Zachycuje i zacatky. Podle sily signalu se snazi zjistit prijimacem polohu. V udoli zustalo temer 50% naschval neposecenych luk. Na posecenych cejky, racci, spacci a velke hejno vran. Bohuzel je trava neuveritelne husta a vysoka. Ackoliv byl chycen, focen a zjistovan v jednom konci, tak ted byl zcela jinde a behal poprve v nejdivocejsi casti, kam predtim nesel, protoze tam byl jiny samec. Markus pujde do zaznamu diktafonem (doufam). Zatim tvrdi, ze ma poznamky, kdy to poslechem kontroloval, ale zaznam by prinesl kompletnejsi prehled a pripadne i lepsi argumenty smerem k pripadne reklamaci u vyrobce.
Ptak by tam mohl zustat. Mozna se funkce zlepsi az bude ve volnejsim prostredi ci migrovat.
Neni vsak vylouceno, ze PTT skutecne spatne funguje. Zatim jako jedine melo vypadky a nebo "velmi slabe" ON, prestoze vime, ze se dobre dobiji a vysila. Nastesti se neukazalo, jako u Boba a Chrise, ze absence dat Argos znamenala konec vysilani. Pokud by slo o technicky problem, urcite by vyrobce vse kompenzoval a byl rad za "objeveni" technicke zavady. Ale odchyt ted se zda byt nemozny (tenatka?) a vzhledem k Markusovi, ktery ma signal, i nevhodny.
Jeste se k technickemu vyhodnoceni vratim.
Lubos

Dear colleagues,
attached you find some pics we made yesterday near Nößwartling (8x photo); Fritz still seems to be well and he has arranged himself to live with the backpack…
Markus can send the coordinates to you.

Best regards,

Pro informaci posilam zaznam pipani Fritze 10.7. v Nemecku. Zcela zasumeny zaznam cca 2 hodiny (nahore-zeleny) ze stacionarniho zaznamniku v krovinach u koleji (jezdil zde el. vlak), porizeny za dobu, kdy jsem zameroval azimuty, je po sw odfiltorvani sumu dobre viditelny (dole, jine vertikalni zvetseni). Ukazuje, ze ptak utekl do vzdalenejsi casti louky a kdyz jsem z okraju neposakene casti domeril, tak se vratil. Urcite nas ale nemohl videt!
Pouceni: i nejslabsi signal je vzdy lepsi nez prebuzeny, kdy vsechny spicky jsou na maximu a tedy se nelisi. Alespon obcas musi ale ze sumu vykukovat (aby se dal v mezere sum ovzorkovat a pak podle toho odstranit).

Hello Markus, this is a chart from our stationar recorder (from shrubs near railway) showing large movements of Fritz (original up and after noise reduction down).

Hello Markus,
look on my analyzis in doc.
Have you still this signal and are you sure that it is fluctuating?
Regards

L.


Hello Markus,
I received your CD with mp3 file of Fritz recorded on 12.7. (according to specially coded date/time that was in the Olympus voice recorder – if this date/time in the recorder was wrong please let me know). This recording is about a month old. In that day beeps were recorded by Argos but we know that later Argos had no messages but signals could be monitored in the field.

In total this file is 10h11min long and beeps cover about 8 hours. Stable level of these beeps indicate no move. It could be in night but 8 hours in the raw is too long.

If you have more recent recording please let me know. If there is still signal we must try to locate and recover this tag.

Unfotrtunately I do not have my car ready this week so only Jiri is perhaps available with the rotating antenna in near future.

Posílám foto, v jaké enklávě se ukrývá Fritz
