(2) Single-phase 2-wire line (100 – 120 V A C[...]

■ Gr ounding T o pre v ent electr ical shock, tele vision interference (TVI), broadcast interference (BCI) and other prob- lems, g round the linear ampli fi er through the GROUND terminal on the rear panel. F or best results, connect a heavy gauge wire or str ap to a long ear th-sunk copper rod. Make the distance be- tween the GR OUND ter minal [...]

■ System inter connections 1 or 2 Icom 100 W HF transceiv ers can be connected as e xciters to the IC-PW1. Non-Icom transceivers can be used, how ev er , band selection will not be synchro- nized f or each exciter . See the f ollo wing diag r ams f or making connections be- tween the IC-PW1 and an e xciter (transceiv er). See p . 5 f or AC po wer[...]

If this le vel is e xceeded, a large e x- ternal relay must be used. • Using non-Icom exciter s (transceivers) when the IC-PW1 ’ s power is OFF T o use the antenna selector of the IC-PW1 [...]

10 2 INST ALLA TION AND CONNECTIONS The control section of the linear ampli fi er can be sep- arated from the main body , doubling as a remote con- troller . It can be placed on the e xciter or in another conv enient place. q Disconnect the A C power cab le. w Remov e 8 screws from the sides of the linear am- pli fi er , then lift up the top cove[...]

■ Setting the ALC levels Bef ore fi rst applying power , make sure all connections required f or your system are complete b y referring to chapter 2. Then, reset the linear amplifier using the f ollowing procedure.

12 3 OPERA TION The IC-PW1 uses CI-V frequency data f or automatic selection of the operating band. Program the e xciter ’ s address to use this capability as f ollows: F or non-Icom exciters , the IC-PW1 cannot be con- trolled using the CI-V function, so this setting is not necessar y . F or transceivers which ha v e multiple antenna con- nector[...]

13 3 OPERA TION CA UTION: DO NO T operate the IC-PW1 before adjusting the ALC le vels properly with the [ALC adj1] and [ALC adj2] pots. (p . 11) It takes 15 sec. f or CI-V line initial settings when se veral CI-V de vices (more than 5) are connected to a CI-V line. For IC-781 users with other Icom CI-V transceiver s: T urn the IC-781 power ON bef o[...]

D ALC circuit The ALC (A utomatic Lev el Control) circuit automati- cally limits RF output power b y controlling the input le vel of the e xciter . This prev ents transmission of dis- tor ted signals when the input signal lev el e xceeds the allow able le vel. The ALC activ[...]
