Salut,
donc une antenne à large bande pourrait couvrir toute les fréquences d'un poste débridé? Gamme de fréquence 2m 70cm ce serait çà (comme la Diamond NR770 h ou R?
Pas besoin de couper le brin alors, juste peut être ajuster sa longueur?

Si quelqu'un peut me donner une référence d'antenne (genre 5/8 ou 7/8 radial less), merci.
J'ai trouvé un site qui raconte comment débrider, une histoire de diode à enlever. Enfin c'est en anglais et il semble qu'il y ai plusieurs méthodes. Je ne sais pas s'il faut juste appuyer sur deux touches et çà marche ou s'il faut appuyer ces touches puis enlever une diode et faire ensuite éventuelement un pontage.

Donc j'ai lu çà:
Icom IC-2100H (IC 2100 H IC2100H) Expand receiver EUR version:
Expand receiver for Ver #02. #06 and #07. (EUR version]
By key funktion:
Switch off the radio.
Push the [LOW/DUP] and [MONI/ANM] , while turning on power.
By diode:
Cut the D-16 on logic board. D-16 is located at centre, and below J2 and is the only NON-SMT diode.
After either mod, you will have:
136,000 - 174.000 MHz FM
(AM and 118 to 135,995 is NOT possible with the IC-2100H)
Et j'ai lu çà:
Icom IC-2100H (IC 2100 H IC2100H) Extended Transmit Mod
For the first time anywhere on the web, the Icom IC-2100H extended frequency transmit modification and mod instruction sheet.
Hold down the second and third front function buttons while turning the radio on. Now turn it back OFF.
Carefully remove the large tuning knob and remove the two hex screws that hold the faceplate on. Pull the faceplate straight of the body without tilting it (you run the risk of bending the pin connectors behind the faceplate).
Turn the faceplate over and locate the main ic chip, set at a 45-degree angle. Just to the lower left and right of the IC, you will see the main pin connectors. Under the lower right corner of the left pin connector, you should see a marking on the pc board labeled as "D16". just below this should be the matching diode, close to the bottom edge of the board. Remove this diode and carefully re-assemble the radio(watch those faceplate pins!!
The radio will now TX 136-174 Mhz. As far as i know, you do not have to reset the memory to make the mod work( i have 70 out-of-band memories stored, all of them worked without resetting the unit!!!!!
Des anglophiles dans les rangs?
