| Modifying the SR731 RF Repeater
I have not attempted this modification and accept no
responsibility for the effects of anyone making these modifications.
You follow these instructions at your own risk.
This is a report from K F Tai from Hong Kong who
has purchased an SR731 RF Repeater from Smarthome in the USA. He has
successfully modified this unit to operate at 230 volts.
As this is a USA unit, it will operate at the USA RF frequency of
310MHz.
Recently I have modified the SR731 RF repeater and it works OK.
I just changed:
- 0.1u/250V to 0.47u/400V
- 100 ohm/0.5W to 220 ohm/1W
- MOV 125V to 275V
There is a rechargeable 8.4V battery inside the repeater, I have tried
to use a 0.33u/400V and find that the output is only 8V. When changed to
0.47u, the output is 9.4V which is sufficient to charge the battery.
If you attempt these modifications, please let me
know your results, and read the warning on the X-10
240 volt modifications page. |
