Maki,

hvala na ispravci, naravno na 2m pomak je -0,6 MHz. Ovdje se radi o tipfeleru prilikom manipulacije podacima prilikom pripreme podataka za import chirpom u vokac. To sam radio prije više godina. Jedino mi nije jasno kako mi vokac ispravno radi i okida 2m repetitore. Brojke izgubljene u bespućima Interneta.  :)

Naglasak mog pitanja je na početnoj i krajnjoj frekvenciji simplex kanala. Tu su "nedoumice".

Sale, 9A3XV

p.s. nego, nisam na repetitorima već godinama, a onoliko koliko jesam na analognima, nema žive duše. Je li situacija na digitlnima drugačija?

Pozdrav,

Ovako ide dodjela kanala prema zadnjem IARU R1 VHF Handbooku:

Channel designation system for VHF/UHF FM channels
Although the FM channels can be referenced by their centre frequency, a numbering/naming system for
FM channels in the 50 MHz, 145 MHz and 435 MHz is recommended (Tel Aviv 1996)

Principle
The system is based upon the following principles:
• For each band, there should be a "designator letter":
1. 51 MHz : F
2. 145 MHz : V
3. 435 MHz : U
• Each designator letter should be followed by two (for 50 and 145 MHz) or three (for 435 MHz)
digits which indicate the channel.
• If a channel is used as a repeater output, its designator should be preceded by the letter "R".
• In the 50 MHz band the channel numbers start at F00 for 51.000 MHz and increment by one for
each 10 kHz.
• In the 145 MHz band the channel numbers start at V00 for 145.000 MHz and increment by one
for each 12.5 kHz.
• In the 435 MHz band the channel numbers start at U000 for 430 MHz and increment by one
for each 12.5 kHz.
Examples
F51 Simplex frequency 51.510 MHz
RF79 Repeater with output frequency 51.790 MHz
V40 Simplex frequency 145.500 MHz (the old S20)
RV48 Repeater with output frequency 145.600 MHz (the old R0)
U280 Simplex frequency 433.500 MHz (the old SU20)
RU002 Repeater with output frequency 430.025 MHz (the old FRU1)
RU242 Repeater with output frequency 433.025 MHz (the old RB1)
RU368 Repeater with output frequency 434.600 MHz (the old RU0)
RU692 Repeater with output frequency 438.650 MHz (the old R70)
