For Sale

The intellectual property to manufacture
and sell Model RP-176 Repeater Controller
and/or Model LT8R LTR Trunkng Controller
Model RP-176 Repeater Tone Panel aka Repeater Controller 

 


 






Designed in 2005, the RP-176 has at least a 10 year lead on the next newest competing controllers.  That's why you don't see great features like an LCD on any other tone panels.  Considerable software for the LCD makes the display extremely useful during operation and also during user setup. All user set parameters are permanently retained in eeprom. A total of 176 codes [64 CTCSS & 112 DCS], are available, more than any controller ever offered . An important point is that all 176 codes decode all the time so there is no limitation as to how many can be simultaneously enabled. All tones and codes heard on the input channel are displayed whether enabled or not. If enabled the Tx cross tone is also displayed. In the acompanying picture the Rx is 131.8 CTCSS and is being regenerated to 131.8 for Tx. No cross. However Any Rx code can be crossed to any Tx code.  The panel is fully programmable locally as well as over the air using DTMF. 



All level controls and dip switch settings are available from the front.  There is never a need to go to the rear once installed.  The panel is 19" W, 1.75" H, 2" D. Smallest, lightest panel ever designed.  The size and weight reduces shipping and packaging costs. 



The reliability is outstanding.  There has never been a failure**  or a DOA and never an unhappy customer.

Model LT8R 8 Channel LTR Trunking Controller  


 







 






Designed in 2008,  the Model LT8R LTR Trunking Controller is the only LTR Trunking  Controller ever to incorporate all the channels [up to 8] in a single small package of only 19" W, 7.5" H, 2.5" D.  Like the RP-176 all adjustments are avalable from the front.  Yep, all 8 channels.  A four line LCD display is divided into 8 segments of 10 characters each. One segment per repeater. The 10 char segments show the complete status of each channel eg "Idle" if not in use,  User ID and Home repeater are shown if in use,  "IDing" if sending CW ID, shared channel or clear and more.



Talk turn around time is the same whether trunking to a free repeater or staying at the home repeater. both are faster than other panels because the slow interconnecting bus is eliminated. Everything seems lightning fast compared to bus oriented panels. Actually, it feels more like talking simplex.



There are up to four plug in two channel boards.  Each operational channel gets its own processor. So that means a four channel configuration gets two 2 channel boards and four processors.  The processors intercommunicate via very fast serial and do not waste time in a token ring.  This means the LT8R can be sold in 1 to 8 channel configurations.  Obviously 2 or more channels are needed to have trunking.



Like the RP-176,  the reliability is outstanding.  There has never been a failure**  or a DOA and never an unhappy customer..

CTCSS, DCS and LTR Decode Algorithms 


The performance quality of a panel is fully dependent on the expertise embodied in the decoding algorithms and coded software.  You will find the decode speed and operational signal to noise ratio the best in the business.  Also, we found a way to error correct the LTR word using the Hamming code.  So if there is bit loss in the 24 bit data word the algorithm corrects it without loss of talk time caused by  repeated waits for successful decode.  Our super algorithms are worth the price of admission alone !!.



BTW..  It's pretty likely that I have designed more tone panels and LTR panels than anyone on the planet beginning with my first tone panel Model TP-154 back in 1991 during my 20 year ownership of CSI.  Now over 30 years experience in tone panels and before that 15 years experience designing TV type displays at Hughes Aircraft Co. for FLIR weapon applications.












Terms 


Terms are flexible. I'll sell the rights to each product separately or  I'd even consider entering into an agreement whereby you manufacture the panels using Gerber files that I'd supply and Idylltek would sell you the firmware 10 up at a time as needed.  This puts you into the tone panel or LTR panel business without incurring any engineering or up front costs.  You would have to enter into a non disclosure agreement to keep all intellectual property that is shared private.  Have another idea?  try it out on me..
