The requirements of the standard for an avalanche transceiver are strict!
DID YOU KNOW THAT AN AVALANCHE TRANSCEIVER WITH STANDARD TEST...
Falls 6 times from 1 meter on a hardwood floor?
Is laying 10 hours in a heat chamber at 70°C?
Is laying 10 hours in a cold chamber at -25°C?
Is laying 1 hour in a water basin in 15 cm depth?
Is exposed 80 hours to direct sunlight?
Has a safety feature against involuntary or accidental leaving of the transmit mode?
All joints between essential parts are submitted to a tensile stress test of at least 10N (1kg)?
After this series of tests, the beacon has to be fully functional to meet the requirements of the standard!
STANDARD SPECIFICATIONS FOR TRANSMISSION PARAMETERS
STANDARD SPECIFICATIONS FOR TRANSMISSION PARAMETERS:
457 kHz (457.000 Hz) ± 80 Hz
Signal strength is defined
Period: 1.000 ± 300 ms
Pulse duration: ≥ 70 ms
Pulse break: ≥ 400 ms
Use available PIEPS CHECKPOINTS in ski areas, huts and ski touring starting points to proof the sending parameter of your avalanche transceiver.
is that wave length that permeates best through snow.
The less air in the snow is existing, the worse the signal can propagate and the receiving range is reduced. An extreme range reduction occurs at low snow thickness (<1m) in glacial ice, since it has only a very small portion of air. The recommended search strip widths are no longer valid! Is an avalanche transceiver sending signals with values at the limit of standard or outside the standard, some receiving avalanche transceivers can be challenged with performance degradation.
DISTURBING INFLUENCE CELL PHONE
Cellphones, especially smartphones, as well as other electronic devices (e.g. cameras), can influence the functionality of your avalanche transceiver in the close range. This applies for all avalanche transceivers!
Possible effects on send function:
- Reduction in signal strength and therefore range reduction for faulty transmitter
- Reduction of receiving range
- Wrong direction and/or distance indication
- Display of additional, non-existent transmitter
