I have updated my webpage with instructions for modifying the CM19A receive antenna.

Thank you for the instructions to add a external receiver antenna to the CM19A.
Helpful from me

Do you need to worry about putting +5v on the signal receiver inside the CM19A?  I assumed that the power injectors I've used (and currently use) apply power in one direction but don't let it pass back the other way.

C18 will block DC from the CM19A receiver circuitry. And, I've never seen a receiver without such a series capacitor on the input (although I still advise confirming one exists).

[UPDATE]   1 L of a week - M,T 5 rooms of new carpet and "we don't move furniture, we just lay carpet...".  Mon @ 10AM FedEx and my DS12A,  Tues: "Daddy can you help install my new garage door? (bat, bat, bat...)", Thur: sat half the day gathering sigs to recall our Sheriff, Fri. more of the same. Sat- recall came up short @$!#@!$!  Sat lunch time added batteries to my DS12 and via CM19A:

  07/12 11:52:38 Rx RFSEC DE:33:00 Contact_normal_max_tamper_DS12A
  07/12 11:52:39 Rx RFSEC DE:33:00 Contact_alert_max_tamper_DS12A
  07/12 11:53:02 Rx RFSEC DE:33:00 Contact_normal_max_tamper_DS12A
  07/12 11:53:03 Rx RFSEC DE:33:00 Contact_alert_max_tamper_DS12A
  07/12 11:53:44 Rx RFSEC DE:33:00 Contact_alert_max_DS10A
  07/12 11:53:46 Rx RFSEC 3E:B3:80 Contact_normal_max_DS10A
                      :)% :)% :)% :)% :)%

So out to garage,  cut a 3" length of rubber roller from an old SM typewriter, an 6"x6" alum. plate that use to hold power transistors, a couple of 1/2"x 1 alum angle, 30" of alum double pane window channel, screws'n nuts, glue ... the 30" of channel will ride up&down on some foam rubbing on the roller which will turn the shaft that will spin (very slowly) a small magnet(x2) which will pass by the DS12.  When installed I'll post some photos.

Progress is being made.
Will be waiting for the added results as you discover them.

[UPDATE] Minor design change - removed large (3/4") rubber roller and virt shaft.  The float is still there with a shorten virt. pvc pipe (1/2") -> change... nylon string up an over the 1/8" shaft and back down to pvc weight.  As the float lowers, pulls string, rotates shaft, spins cross arm with 2 magnets - think shaft with propeller - magnets on prop tips.  I had some mag-switchs with magnets from the local model train store.

I've soldered in a switch that runs to the aux input of the DS12A.  Ya, Rube Goldberg strikes again - but man is he hav'n fun!  A RaspberryPi runs the sump pump every 2 hrs for 40 seconds.  A WeatherDirect unit watches temp(in/out) & hum.  If the hum drops X10 opens a sprinkler valve -> misters. And now after some calibration my RasPi/19/12/float/string/magnets will keep track of soup in the tank.  Still a little cleanup/tiedown/etc.

If you 'view image' and remove dev2.jpg you should get a list of other pictures.  That's a penny on the black plate - ref size. Also http://lidderdale.net/hydro/ My favorite time - Sunday morning, real early.

Thanks for the updates on your project.
I believe I had looked at your web site awhile back. As the front page photos looked very familiar.

Very possible as I've had my CM11 for ??? 10 years+???  In my last post I went in to detail on my RG device but little about the X10 side.  So the CM19A sends:

 07/15 06:22:20 Rx RFSEC DE:33:00 Contact_normal_max_DS10A
 07/15 06:22:22 Rx RFSEC 3E:B3:80 Contact_alert_max_DS10A
 07/15 06:22:22 Invalid parity 
 07/15 06:22:22 Invalid parity

about every 1.5 hrs and when the magnet moves past the switch I get:

 07/14 15:07:31 Rx RFSEC 3E:B3:80 Contact_normal_max_DS10A

Key:  "3E" and "normal" 

Then there's a PHP script that does CURL my raspi CM19A log.  Does CURL weatherdirect.com/myacct for the temps/humd.   MYSQL db keeps track of everything. 

Everybody - thanks for the advice and ear.

When I first got my DS12 - no house code, no unit code I was  B:( but it works just fine with my CM19   :)%
Although documentation as to it's output is a bit lacking.

Thanks for the help & support.

I am not too sure if the X10 Protocol file will give you any more information. The Security type messages are mentioned in it.

The secure messages mentioned in the referenced document have nothing to do with the RF Security Protocol which is similar to the regular RF protocol. I believe Charles Sullivan had documented it as it pertained to security devices but am not sure where to find it. I also documented it but it's on a long retired W98 PC.

For reference, I have added a picture of an eggbeater mounted atop an MR26A which used the same case as the CM19A.
