Lowe HF-150 keypad not working
I have a Lowe HF-150 with the outboard keypad. The keypad has stopped
working. Now when a key is pushed there is no normal buzz. The pad has no effect. I think the pad operates a circuit internal to the receiver and likely the problem is located there. Anyone have this problem and solved it? Any ideas on what might be a possible cause wouldbe appreciated. Tnx Robb WB8BHU |

Tnx Robb WB8BHU Don't know if this is relevant to your problem; but my keypad dies when the supply voltage drops, even though the receiver works perfectly normally. I don't remember the specific voltage where the keyboard drops out, but it might be worth checking. Good luck, Dave |
Check the capacitor at the output of the 8V regulator. If this cap goes bad,
this line will droop. Pete "Dave Holford" wrote in message ... Robb Leamy wrote: I have a Lowe HF-150 with the outboard keypad. The keypad has stopped working.
