VU2BBB -matheran repeater: COMPLETE INTERFACE
http://vu2bbb.blogspot.com/2008/07/complelete-interface.html
Both PIC mico-controllers are linked together and monitor the entire repeater system. Pic16f72 ADC port monitor 12/180AH battery voltage. It has its own 5v smps adaptor (cell phone charger), to check if mains supply is present or not. Subscribe to: Post Comments (Atom). Meteor M2 Wx images using RTL SDR. My Hombrew Wx Rx.

VU2BBB -matheran repeater: VU2BBB Location:- Matheran, Maharashtra, Near Mumbai
http://vu2bbb.blogspot.com/2008/07/vu2bbb-location-matheran-maharashtra.html
VU2BBB Location:- Matheran, Maharashtra, Near Mumbai. Freq 145.000Mhz 600 Khz Shift. LOCATION:- MATHERAN , MAHARASHTRA. HEIGHT 2467 Feet,. Cordinates N 19. 00.500 , E 73. 17.013. CURRENT STATUS- ON AIR. This blog gives an idea of an initial experimentation done with PIC MCU based homebrew repeater interface to control. Repeater in a very remote location. After serving for a while interface and repeater were damaged by lightening. At present repeater is fully functional without remote interface. Known pro...

VU2BBB -matheran repeater: CLOSE UP - TELEMETRY INTERFACE
http://vu2bbb.blogspot.com/2008/07/close-up-telemetry-interface.html
CLOSE UP - TELEMETRY INTERFACE. Recently I have updated the program and it includes remotely switching ON -OFF repeater. It uses DTMF six digit code to do the operation in a specific sequence, there are 2 different codes for ON and OFF. It has to be incorporated to prevent fishermen entering in to input frequency of the repeater, as the 2m band highly infested by fishermen in Mumbai. Hi I m Gayan 4S6GGS in Sri lanka. November 5, 2010 at 11:57 AM. This is great interface i like it very much!

VU2BBB -matheran repeater: SIMPLE PIC INTERFACE
http://vu2bbb.blogspot.com/2008/07/simple-pic-interface.html
I homebrewed interface based on Microchip PIC16F628 for controlling the repeater. Just few lines of coding was required and the interface worked very well. This comment has been removed by the author. July 12, 2010 at 1:14 AM. Im din from malaysia. can u teach me how to build this interface? July 12, 2010 at 1:15 AM. Subscribe to: Post Comments (Atom).

VU2BBB -matheran repeater: CLOSE UP OF DUPLEXER
http://vu2bbb.blogspot.com/2008/07/close-up-of-duplexer.html
CLOSE UP OF DUPLEXER. Since duplexer was not used for few years, it required retuninng. It took 2 session and almost 3-4 hrs to get it perfectly working, while doing on air test. We are using Heliax coax about 37 meters in length. Stack 5/8, 6db gain antenna is on the 100 feet height Tower. Subscribe to: Post Comments (Atom). Meteor M2 Wx images using RTL SDR.

VU2BBB -matheran repeater: TX, BATTERY AND INVERTER
http://vu2bbb.blogspot.com/2008/07/tx-battery-and-inverter.html
TX, BATTERY AND INVERTER. Entire setup may look ugly, but everything will be neat and tidy shortly. To deal with long hours of load shedding a 12v/ 180AH battery was installed. Branded Microtek inverter can charge the battery efficiently even in low AC voltage (100-300VAC). Inverter gives uninterupted ture sinewave powers to SMPS power supply , which powers both the radio. Tx Radio, Icom 2200H is kept cool by AC operated cooling fan. Subscribe to: Post Comments (Atom). Meteor M2 Wx images using RTL SDR.
