[CQ-Contest] Wireless Remote Control Relays

[Milt -- N5IA]

Thanks Gary for that information.  It is the first of this kind I have seen.  Pete, N4ZR has reverse engineered the board and has produced a similar instruction.  From the info from the two sources, I can probably get something to work.

The 8 relay board is not now available as you can see in the E-Bay notice.  However, the 4 relay and 15 relay boards and remote controls made by the same company appear to be available for purchase.

I can say that the boards and relays are high quality, and should be of use to lots of folks who might want to put a small amount of work into them.  

Pete has an article in the NCJ about one year ago that details what he has done to use his 8 relay board remotely, including inducing the 310 MHz RF signal onto his feed line to get more distance to his antenna selection location.

Thanks again, and good luck to anyone who tackles the project.

They are probably the nearly the same as this: http://www.ebay.com/itm/130545242235?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

  A question to the informed masses.

  A year or so ago I purchased some wireless remote control, 8 relay, modules from some source on E-Bay.

  Obviously at the time the units appealed to me, and apparently the price was right because I purchased 10 of them.

  Well, they have sit in the USPS shipping box for this length of time and I am now trying to figure out what project I had in mind for them; and how to use them.

  SOOOOOOOOOOO................

  Does anyone have any experience with these units which have a sole identifying mark, silk screened on the RX and relay board, of CDKZQ-8L.  The manufacture date is 2011.10.04.

  These units apparently work on 310 MHz.  The only result I get in a web search is a Linear Delta Remotes company.  But nothing they show for products resembles these units.

  The tiny remote control transmitter has larger, red colored keys numbered 1 & 2, and 3-8 on smaller black colored keys.  It has a small telescoping antenna.

  These units are very well constructed, operate at 12 VDC, and look to be SPDT relays with 3 connections per relay on the terminal boards.

  Does anyone out there know anything about this unit; in particular how to program the channels for control of the eight relays?

  For anyone wanting to see them, respond directly to me and I will send you a couple of jpeg images.

  Thanks in advance for any assistance that can be offered.
