What hand-held(key-fob?) device(s) can I use  to control a Lamp-Module?

PS: How do I insert a picture from my desktop?

Everything you need to control a lamp with a keychain remote.    https://www.x10.com/packaged-deals/home-automation/kitwirelesskr19a.html

The X10 kit has all you would need.
The key-fob, the RF transceiver to convert the remotes X10 RF signal to the power line and the lamp module itself.
Even if you have a lamp module now. You may find the kit price is less than the individual item themselves.

Kit received.  Kit installed.  Set-up transceiver with two lamp-modules connected.  Each lamp-module is 20 feet line-of-site to the transceiver. 

But, I have to get 10-feet line-of-site with the fob to activate the transceiver/lamp-modules. 

Is this normal?  If not, what might be wrong?

Thanks.

There are lots of things that can affect a RF  signal cordless 2ghz phones, micro waves large metal objects (fridges) even your wifi router.  Id try moving your transceiver to a differentvlocation it doesn't need a clear l8ne of sight ot the modules. I'd also try a new battery in the flob.

Just curious... Are there any other hand-held devices that are compatible?

The HR12A Palm Pad may have better range. Be sure the antenna on the transceiver is fully extended and plug the unit in at a location close to where you typically use the remote.  As Mr. T said, you don't need to be concerned about placement of the transceiver relative to the lamp modules as those are controlled through the powerline rather than RF.   Also, the SR751 RF Range extender may be helpful in expanding RF coverage.

I personally  don't  like the key flobs but the kr22 does seem to have been improved with a better transmitter https://www.x10.com/x10-home-automation/kr22a.html. The HR12A is my preferred remote. https://www.x10.com/hr12a.html

Again... Thanks for education.  New battery in remote.  I suppose it never occurred to me that 15-feet line-of-site between the fob and transceiver would have so many reasons for not working better.

Well there is also the thick air reason.  rofl

Newer versions of the TM751 use a superheterodyne RF receiver which has a fairly narrow bandwidth and may or may not be accurately tuned to 310MHz. The KR19A may also not be accurately tuned to 310MHz. This could explain the short RF range.
