Ajutor
Raspuns nou
eu si prietenul meu Atty zburam in acelasi canal ,si m-a invitat sa incerc sa-l bruiez (la sol of-cors :D )
- a pornit omul statia ,a pornit receptorul ,a asteptat 3 secunde......si m-a invitat sa pornesc si eu statia !!!
(ambii eram in acelasi canal ambii cu PPM)
SURPRIZA!!!
MODELUL IN CONTINUARE ASCULTA PERFECT DE STATIA LUI IAR DE A MEA DELOC!!!
ambii ne aflam la mai putin de 1 m de model ,iar statia mea parca nici nu era pornita.
receptorul pe care il folosea pe numele lui OCTAVA produs de MZK include o functie care se cheama TSR ( Transmitter Signature Recognition) si aceasta functie nu-l lasa sa asculte decat de statia "de pe care a boot-at"
bineinteles ca invers pornind intai statia mea si receptorul dupa ,modelul asculta DOAR de statia mea fara sa mai asculte de statia originala a proprietarului.
e?
ce ziceti de treaba asta?
am forat putin pe net si am gasit niste descrieri pe care nu am timp sa le traduc acuma dar se intelege foarte bine:

A Professional Series receiver with high reliability and interference resistance due to a special RF-input circuit design as well as the application of TSR, DSP, HOLD, FS and QR program functions. This receiver allows safe flying in areas with high interference levels where flying was formerly impossible.
The receiver contains a fully programmable FS system on all channels.
DSP (Digital Signal Processing) describes the function of a very precise digital filter inside the microprocessor decoder which contains adaptive algorithms following the signal/noise ratio of the received signal. This filter sends correct output pulses to the relevant receiver channel outputs, incorrect pulses are discarded and short term replaced by correct pulses received last.
TSR (Transmitter Signature Recognition). The receiver learns and remebers the number of channels, the keying pulse lengths and the approximate frame timing of the transmitter. After this only a few seconds lasting "booting period" the receiver will only listen to your type of transmitter. This so called TSR process is refreshed everytime the receiver is switched on and works with all types of FM transmitters.
HOLD: In case of signal loss all servos are held for 2 seconds in their last position, after that time these pulses decease and can be without any delay replaced by oncomming correct pulses or fail safe pulses.
FS: In case of FS mode activation (FAIL-SAFE mode, programmable by the user) the servo outputs keep for approx. 2 seconds their last positions (HOLD), after 2 seconds the servo outputs change to fail-safe servo positions formerly programmed by the user.
QR: Quick Recovery means a delayless recovery of the correct signal after its previous loss or after fail-safe activity (much faster than with PCM-FS systems).
Notice:
This receiver is assigned for the use of standard size crystals. We strongly recommend the use of high precision MZK crystals.

nu mai spun ca receptorul merge cu orice tip de statie,ca are auto-shift recognition .......s.a.m.d.
si cel mai buna treaba este ca e mai ieftin decat un receptor PCM.
