Thread-topic: [CRTech] Re: are BE AM 5KW modules FD?

I have had to replace the large caps in the modules to help them.. some service white paper mod… very effective and highly suggested!  but only thing I know of for sure is that the HD units can’t be swapped for the analog ones.. they don’t have much to show that one is either type visually other than some stripes on the front.


Other than that I never ended up using a module on a different freq.

Ymmv… right?

The IB says:


''The AM transmitters are configured for a specific frequency when shipped from the factory.  The transmitter is equipped with  several frequency dependent parts and circuits.   Due to the frequency dependent parts, frequency dependent circuits,  and specialized procedures, the transmitter cannot be reprogrammed for a different frequency in the field.  If the transmitter is required to be programmed for a different frequency, contact the Broadcast Electronics Customer Service department. ''


They sell frequency kits for the band in many segments, but not having a schematic I'm not 100% sure any of those parts in the specialized kits are in the PA module(s).  My foggy brain says they are not, but you may have to confirm with the factory to be assured they work.

In the back of my mind I recall a mention of some broad frequency-dependent parts. I'd touch base with the factory...you might need to send the module in to be tweaked.

HI everyone, are the RF modules in a 5KW BE AM transmitter frequency dependent? I would like to take modules from a BE transmitter on 1060 kHz and put them in a 1370 KHz transmitter. I don't know the module number but I don't remember the model number ever changing.
