2720, 2489, 2170, 2000, 1865, 1800hz, These are frequencies which can be easily covered by an audio amplifier. A cb radio, amp or sealed glass tube is of little use. I am not sure how to design an antenna for that wavelength as a dipole would be many miles long but a dummy load would be easy to...

Zener diodes are generally only used in dc circuits. The tuner alone is sufficient to protect the linear from reflected power, i.e. high swr. I can't imagine what you're trying to do doing anything more than giving you an rf burn but to each his own. Keep us in the loop because I for one am...

I don't know anything about swing mods. If I want more audio I use a power mike and leave the radio stock. Am deadkey with the amp on that radio with rf power turned down is probably 10 watts if it is like my 2970n2. with the amp off it should be under 1 watt. I can't see what has been done so...

pull the plug on the amp board with the green and yellow wire. now with the voltmeter set to 20v put the black wire on the negative of the power supply. keep the radio keyed up and touch the red wire of the voltmeter to the back of the plug touching one of the terminals within. whichever wire...

I'm in leinster and I could trade you a 12v cb amp for it. How many watts is the bass amp?

I would put the switch on the green or yellow wire in that picture. when i tried it on my n2 it didn't matter which, but i put it on the + wire as most circuits are negative ground. Because you have cut the power to the amp you will be transmitting through the power transistors and you may blow...

When I was younger I used to spend my nights on the top of a hill talking on a cb with a neighbour. He used to talk until the radio got warbly on tx and then let the car run start. I know the battery wasn't great in the car but in general if you are not transmitting about 3 hours could be...

here is my experience of programming the uv5r+. afaik the firmware should be the same with only minor differences. robb has this covered fairly well already along with the numerous videos on youtube but sometimes another view helps. here are my presets. I find that my radio jumps frequency a...

Locally and anecdotally, I have heard that sometimes when arrogant folk wish to insult the beauty of another's xyl they will allude that the xyl wears a brown paper bag over the head during mating.

I hope when china sends a man to the moon that they leave a half wave passive antenna there for 10 or 11 meters. Just drive 2 stakes there in sight of earth and hang a 1/2 wave dipole with no feedpoint between them.

why the rudeness marconi?

Most programs are stored as 256bit extended ASCII. RTTY or PSK31 which were traditionally used for sending text only have a small character set consisting of little more than letters and numbers. The free fldigi software suite, which has an app for sending PSK31, also has an app called flwrap...

i don't know who this fellow is but he looks like another radio enthusiast.

there are some brand names like uniden and certain model numbers that will bring ridiculous prices such as more than a new radio because they are classics. that is why sellers use ebay to sell those radios. that is how they make their money and there is nothing wrong with that so long as there...

welcome to the forum. as i am from ireland i have heard many spanish stations and possibly yourself calling dx many times but i have not operated in a while. there is only 1 female in 30 divison i recall hearing so its apt to be you.

nothing wrong with the radio most likely. some high end radios have auto notches and beat cancels and manual notches that could deal with it, so put up with it or trade up i guess.

have you tried turning on the noise blanker?

the ts 850s is a superior radio to the dx70th as it has a processor and is near the top of the sherwood engineering receiver lists. the alinco does the same power out but it also has 6 meters and is a much younger radio. i find that when 2 homebases are in the one house that only 1 is used so i...

The only study materials i know of specific to ireland are on the irts practice cd sold on the irts website. The owner does allow copying the material so if you have broadband and a torrent client such as transmission or utorrent I can send you a private torrent of the cd. and other pdf's i...
