24GHz equivalent to the HB100 doppler unit (CDM324)
Also you can still get hold 24GHz gunnplexer type modules from PIRs sensors, good search terms are:
As it currently stands I have only just found these modules, so I'm not sure if they can be tuned internally.
It should be possible to add this module on to the same IF strip/modulator currently in use for the HB100 making it dual band.
Good morning groups.Following on from the WBFM activity at Finningley round-table this weekend, and the potential use as talk-back for nanowave operation, I thought both groups might be interested to know a 24GHz version exists at a similar cost.
"Honeywell DT-7450UK" & "Honeywell DT-7550UK"
Hope this might spark up more interest in simple microwave fun.
