Raytheon Ray 90 private freq programation

The Raytheon Ray 90 is a marine vhf radio , probably manufactured by JRC for Raytheon , has all the tipical features of shipboard marine radios , hailer and all that stuff , but has an cool feature ,the so called private frequencies , private frequencies are 10 channels that you can program between 154 to 164 mhz , those memories are accesed putting the radio in international channel mode , thats pressing the (I/U) , an then pressing the (P/W) key ,then one of the numbers of the keyboard , but supossing that the radio is new or hasnt been used in a long time , you must program it . How to do that , open the radio , and locate a small switch behind the front pannel , the swicht is above an EPROM , and is marked "PRIVATE" , with the radio powered on push the "PRIVATE" button , and without releasing it , press at the same time the (M) button , without releasing it , enter the desired frequency 155.000 , in this format , 55.0000 , then release the (M) button and press the (P/W) button , then press the desired number on the numeric pad , all this with the "PRIVATE" button pressed , release the "PRIVATE" button , and you should see the channel like this , FFF 01 on the screen . now you are done ! , all this info was found using the test and error methodology , it took me and hour to figure how to program the radio , based only on what keys sounded when i was holding the private button !

Naval air exibhition : Valparaiso

El cheapo 9:1 balun

As you should know , im still in college , in a simple equation that means , -less money - fun + lots of study= quick and dirty solutions , today i had some spare time so i decided that i was able to build a 9:1 magnetic balun for a small random wire , that way i can hang it anywhere , so with lack of time money or toroids , i found the a dirt cheap source , yeah , Power supply toroids , computer power supplies have lots of toroids , and the only things needed for removing them are a pair of pliers and a screwdriver , here in valparaiso (a university driven city ) is common to find them in the dumpsters behind IT faculties , or labs , so i had two of them on hand i managed to recover two toroid with minimium effort , i got two toroids of abt 1 inch wide , green blue ones , i didnt have the correct permeability coef expressed as you should know in teslas , so i started to experiment , picked one and winded 20 turns for the secondary , and 10 for the primary , armed with a piece of wire to act as antenna , and a crappy monimatch style SWR meter and offcourse an HF rig , also my mothers patience for not being able to watch tv (anyway thanks mom for not bitching me for ruining the news hour )! , i started to try to find the impedance , how , well i know two thing , in order to get a measurement from my crappy SWR meter i have to find a point where the impedance is between 35 ohms and 60 ohms otherwise it will be infinite , finding that point with the primary , i proceeded to trim the secondary , and the best match was , Secondary 14 turns of doorbell wire , and the primary was composed of 2,5 turns of doorbell wire , offcourse performance is poor and it will only used with QRP power levels

Thats what i call CAT control

Situation update

still no water in some zones of the central part of the country , the country has been stabilized thanks to a military force , finally a president of change has assumed the direction of the country , let me introduce you , our president , Mr Sebastian Piñera , the guy that came to put order on the country , after 20 years of leftist inefficiency , we finally elected him , and kicked out the leftist from public offices , we have the hope that he will bring back the social liberties that the upper middle class has lost , like the inverse jail, for 20 years we had to built our own fortifications to protect us from the lumpenproletariat and the thugs , now he has the power of change , he can change that reality , making police more efficient , forgetting the human rights for a minute , that are a kind of obstacle to justice , thats what we needed a businessman directing our country , in a executive way , i support our new govt , our troops , our armed forces and god bless you all ...

CHILE , CENTRAL ZONE ,RETURNING TO NORMALITY

THE CENTRAL ZONE OF THE COUNTRY IS SLOWLY RETURNING TO NORMALITY , IS EXPECTED THAT TOMMORROW THE SUPERMARKETS WILL OPEN , TODAY WE DIDNT HAD POWER FAULTS , NOR WATER CUTS , SO WE CAN ASSUME THAT WE ARE SLOWLY GOING INTO A RECONSTRUCTION STATE , THANKS TO ALL ...

The (in)famous Preamplified mic

Well , after Trying the original hand mic that came with the System 600 Hf transceiver i decided on one of those long nights of insomnia to build a Preamplified microphone, using just what i had on hand , mostly parts from the junkbox , well i ended modifying an existing design , and putting , The main transistor is a 2n2222 , and provides more than the nescesary amplification to drive this nice HF radio .

Quansheng Surecom TG-UV dual band radio review



I bought about two months ago a Quansheng Dual band radio , it features all the bells and whistles of a more expensive radios , but no DTMF (Do you really use DTMF Everyday ?) and for 130 USD with all the accesories plus an extra battery , Quality is respectab
le , soldering at component level is aceptable , Yes i opened the radio, couldnt wait more than a week without trying to open it , well as usually i bought the external microphone, and Radiogearpro the vendor sent me as gift a covert earpiece , the radio is thought , uses a SMA-F Conector ,so i ordered the adaptor to bnc , to be able to hook the radio to my external antennas , has a fool mode , that converts the radio into comercial mode , replacing the freq display in memory mode to a Channel mode, just like the old FT.23r from yaesu , reception is superb for the price , the receiver kicks in the butt my icom ic-t7e handheld , both in uhf and VHF , things i miss Airband ,and more wideband reception , but for a $100 USD radio , FM Broadcasting reception is crappy , Thats what happens when you try to listen FM WIDE on a narrow filter , for the price is an aceptable radio , i programmed the local repeaters , FRS/GMRS radios , and Finally i got a radio that was able to do 6,25KHZ steps for PMR446 standard ,now i can also talk on PMR 446 . also marine band channels were programmed including the CH16 for emergencies



Why the hell is tinky twinky is stalking my radio !


It Would not take to long befor our goverment will start to put Warning on French fries About the possibility of having a hearth attack , or making hookers to wear Tshirt that say "You can get more than a good time from this hooker "













DIY electronics lab cart


Have you ever dreamed about having a little workbench that you can haul around the house , tired about those portable wood working workbenches that aren't practic for working in electronics , being on a shoestring student budget i had to design and build one with what i had on hand , the solution came in the form of a TV rolling table , that with some modifications became a nice electronics workbench , so this is the result after an evening , some screws and wood :

added a soldering iron stand , a power supply , multimeter , lab magnifier , and a screwdrivers holder
