[Repeater-Builder] Kenwood TKB-720 CTCSS tone input location
Hi Can anyone help me with the physical location of where to inject a variable CTCSS tone into the Kenwood TKB-720 radio. I do not have the schematic or manual just the connector pinout. So a good description would help. I tried adding it to the audio being sent to the audio input pin in the accessory connector but it must be filtered as the tone does not get thru. The repeater version (TKR-720) has another audio input pin but that pin is used for frequency selection in the TKB-720. Thanks Byron Yahoo!

Accessory Connector Pin 3 is the DI Modulation input (both signaling and audio). Pin 2 is the Line mod inpug Ground GND. Pin 5 is the Line input, modulation input. good luck... skipp www.radiowrench.com Hellewell, Byron [EMAIL PROTECTED] wrote: Hi Can anyone help me with the physical location of where to inject a variable CTCSS tone into the Kenwood TKB-720 radio.

[Repeater-Builder] Re: tx combiner follow up... UPDATE 2
I get to stick my neck out first again... I've cut out mucho and added some comments. ... 6 Motorola MTR2000 100W repeaters, I'd probably Cut the repeater power output down a bit. Since you have narly antenna gain, I'd probably back the repeaters down to 80 watts to possibly improve the unwanted products from the power amplifiers (which can be measured). Also part of the system are a factory tuned Telewave M101-150-6TRM TX Combiner Did you check the combiner for proper tuning? All is rarely plug and play in the real world. Trust but verify. (Cavity/Dual Isolator type), and a Sinclair RM201-112S1B RX Multicoupler fitted with a BP Preselector (with 1MHz pass-band, and factory tuned to 165.625), a Hi Level Bipolar preamp (Angle Linear brand / anglelinear.com), Crap, I just took a look at it. Not enough protection... by a long shot. You need to boot the 1 MHz band pass filter and get a real serious vhf preselection network. As mentioned before, you should also add some serious receiver protection in the transmit combiner side/path. and a 12 port power divider. Using 6 ports..? Every other coax jack should be used to balance the internal dividers better and mo isolation. Between the preamp output and the power divider there is a 2dB pad fitted. Not good, the horse is already out of the barn... Since we only use 6 output ports of the 12 available, the remaining ones have been fitted with 50-ohm terminators on them. Should be every other port as I described above. Antenna system consists of two Decibel DB228 8-dipole arrays, mounted on a 90ft self supporting tower. Nice... RX antenna is at the top, TX is mounted from about mid-tower down. Vertical separation between antennas is not much due to tower height limitations, and each antenna's length, but each DB228 is mounted on a separate adjacent tower leg. Feedlines are 7/8 hardline running on separate tower legs If the site is on a hill, you might do better with a bit more vertical seperation trade. Lower the tx antenna if possible. Increasing the vertical seperation from 45' to say... 65' will help a lot. up until the point where they start to get horizontal to be routed into the building next to the tower. At this point they run parallel to each other for about 40ft. Parallel as in right next to each other? A big no-no even for 7/8 Hardline. The two lines had better be min 6 inches away from each other in the the inbound tray. Combiner to repeater TX port jumpers are made of Belden 9913, From Telewave..? or you made them up? You need to boot the 9913 and use RG-214 min or 1/2 inch superflex hardline typical. and between RX Multicoupler and RX ports we were using 100% shield RG58. Crap... boot the RG-58 right away. There is no real 100% shielded rg-58 that I've ever measured. Since at least one person expressed concern over the usage of said cables, we changed the RX jumpers to RG142. Most of the pro repeater sites out here also use RG-214 for the receiver side, unless they use hard line or older RG-9. TESTS One of our first tests was to look at the combiner output with a spectrum analyzer trough a Lossy T. It looked pretty clean with only two or three smaller peaks on the sides of the main carrier, all between 40-50db down or more. Not good enough... did you use any main signal notch cavities with the test set up described below? You are not going to see the problem using what you describe above. Lunch takes me away (I like to eat)... more later on. cheers, skipp Yahoo!

Re: [Repeater-Builder] 220 Repeater and Gear for Auction
Most of the commercial radios and repeaters in the 220 MHz band are designed for amplitude-companded SSB (4K00J3E) operation and cannot be economically converted to conventional FM (16K0F3E) operation. I was recently given an ESP1000 repeater made by SEA, Incorporated, that is in mint condition. I thought I had a valuable asset until I realized that the only components I could possibly use were the chassis and front panel.
