I have a SP-2000 mated with a FT-950,but the volume is so low compared to the FT-950 speaker. Any suggestions of how I can increase the volume?

I have the same setup and i dont have any issues with low volume.

Are you using a correct cable?
- maybe the cable be stretched, oxidized or compressed in such way it is almost shorted?
- are you using some cable that may contain attenuator/resistors inside the connectors?

I am using the cable that came with the unit,and connecting it as instructed. I am very dissappointed because I can have the AF/RF gain set to max,and it is very soft compared to the internal speaker.

Unit or cable is broken, thoroughly check the cable for damages/try another hookup cable, if that does not work, the fault is most likely inside the SP-2000, warranty return?

At full volume and in front of the speaker your ears should fall off  Grin

Sounds like a faulty speaker, to me. I know my FT-950 is super loud with an external speaker.

BXO:

I'd first clean all movable contacts in the speaker....switches, pots, etc.  I have a Kenwood speaker with built in filters and push-button switches that drive me nuts!

Then either check the continuity or replace the audio cable and see if this corrects the problem.

Do the simple stuff first!
