    I'm glad you took that as an attack on your self worth, that's how other people feel when you talk down to them regarding their knowledge level and equipment. Mission accomplished. I would love to "leave you alone", but, just like you, I like to excersize my First Amendment guarantee to free speech to treat you like you treat others. And as for being your "judge", I wasn't judging you, simply accusing you based on the clear evidence at hand. And while I await the next smart remark from you, I think I'll give the TS-990 a rest and play with my "walkie talkie" (which made me a 600 mile contact last year off my homemade 8-element beam over the Great Lakes on 4 watts VHF). To all others that happen to stumble upon this nonsense in the activity stream, I sincerely apologize ~ but this guy needs it.

    Since the voltage drop remains the same across an LED bulb as the current through it changes, you subtract the LED voltage drop from the supply voltage to obtain the voltage on the resistor. (and thus the current via ohms law). Three 3v LED's in series would be a total of 9v across the string. At 30mA per series LED string, you pull 300mA having 10 of those in parallel. In other words, you have a total of 9v drop and 300mA draw through the entire network of lights. That is too much for that power supply. Given that the addition of a limiting resistor to further lower the brightness will increase the loss, its likely that trying to limit the current further with a resistor will simply shut the lights off. Step one, get a more powerful supply. For simplicity sake, lets do the math on just one 3v 30mA LED connected to a 9v supply. 9v - 3v = 6v across the load resistor. if we want 30mA through a resistor with a 6v drop, 6v / .030A = 200ohm. And the power rating of that resistor is 6v x .030A = 0.180W. This...

    R2D2, The Amateur's Code is based on a set of principles. Being considerate, loyal, progressive, friendly, balanced and patriotic. You seem to struggle with the considerate, loyal and friendly parts. You may be very knowledgeable in the world of radio communication, but a true ham you are not. Sure, not everyone had it as rough as you did growing up, and certainly many lack the resources to jump straight into the deep end of this hobby, but none of that gives you the right to talk down to people just because they do not have the desire or ability to follow in your specific path. Many radio amateurs never go beyond a technician license and a "walkie talkie" is all they will ever need to enjoy their hobby in their own way. Who are you to tell others their equipment isn't good enough or that HF is the only way to go? Who are you to assume you know how they wish to pursue their hobby? Who are you to belittle new hams for their lack of knowledge? This is a hobby, plain and simple. It is what others choose...

    Hey team, First post, wanted to ask if any one knows the answer to this.... Building Turnstyle antenna and the connections to the dipoles are using "pig-tail" wires launched from the end of the coax phasing harness. About 1" long. Do you include the "pig-tails" as total length of coax with my calculations? Kinda guessing it's an impedance bump and who knows what that impedance is.

    Guys I want to use an unused chimney in the building to run some coax to a roof mounted Diamond X200A. I can get some LMR400 and drop it right into my office through this chimney pipe. VHF to start, will work on different antenna for HF later. Do you see any interference with this metal chimney pipe? I think it is aluminum but it might be steel/iron. I will investigate. If no interference it is like someone ran a 6 inch conduit to my home office just for Ham purposes! Any input is appreciated. Gene KJ70GV

    I am now listed! I can start shopping for the right radio(s) and antenna! Will probably start with the repeater on the opposing peak with a triband HT to get the hang of it and then need to figure out my antenna situation in this mountainous valley for HF. Thanks for the advice people! KJ70GV Gene

    Your kind of confusing HF with UHF and VHF. UHF and VHF are entry level options for the beginner, not that everyone there is a beginner.. I spend an inordinate amount of time listening to 6 meters, looking for band openings and working the 10 meters band openings. HF as long as there is not a solar or atmospheric event, you can always find someone on 40 / 80 or 160 meters. You don't have to learn morse code to be a ham, so no reason to learn morse code unless that is something you are interested in.

    The 8800R should be able to save frequencies / PL's in banks. Say you live in Western Pennsylvania and you want to travel to Eastern PA or New York state or OHIO, you can program the radio with separate repeaters in each bank and when you cross the line and go out of range of one set of repeaters you can switch banks and open the other programming with the different PL's and operate on those repeaters without having to manually edit the frequencies / PL's. You can also choose to monitor by name as well as by frequency on the display. The Yaesu is quality compared to the TNT style radios which is crap. You get a much better front end and a more durable final transistor with fold back. You should thank the person that GAVE you that radio, its worth at least $250.00

    Yaesu FT 8800 is a dual band radio. Designed to operate on amateur radio frequencies. Both sides of the transceiver scans independently on either band. It can scan 2 meters or 70 cm simultaneously. If you are transmitting on either band and the opposite side of the transceiver is in the same band it will mute the other half of the radio until you stop transmitting to protect the front end of the other side. The best programming software i've found is G4HFQ. You can purchase a programming cable online for about $15.00 The Yaesu programming doesn't work very well and doesn't allow you many editing options.

    The microphone lock feature (Upper right side of the microphone) locks all the buttons, except the PTT, on the mic only. Locking the radio requires selecting Menu item 21 and setting it to ON (Page 24 of the manual.) It will not lock the PTT. That's a separate function (Menu item 22.) See page 63 in the manual for further explanation of the lock functions.

    Demonstrations have now started in UK (solidarity with USA). But they haven't started the arson & looting over here (yet). Yes l agree Dan. When they destroy & steal other people's property they have gone too far. In addition to that, the public in general will not sympathise with them. We will be watching to see how it goes for you in November. But the land of the free is as Nicola said..... "Not so free". CNN like any other media outlet in any other "western" country, are only interested in "the story". They want the demonstrations to turn violent as the better the story is, the more money they make out of it. A prime example was when Titanic went down. New York Times (and others both sides of the pond) paid out many thousands to those passengers & crew who survived on that fateful night for their story. The more sensational/violent the story was, the more they would pay. Simply because bad news makes money.

    Most "large" companies will use external testers for the very reason you mentioned. Small companies may not. I have a City & Guilds 2377, therefore l am qualified to test all the electrical appliances (anything that plugs in the wall is subject to compulsory annual testing). Like the ham qualifications, that certificate is for life. I was surprised to discover that no refresher course is required, even if (like myself) a person has not done any pat testing for a number of years. However the electronics company that l worked for never asked me to test appliances. The reason for that had nothing to do with having the testing done by an impartial external tester. It was simply because the electronic work & testing that l done was of much more value to them. Any fool can obtain a C&G-2377 qualification, it's only a 3 day course. But it would take years to train someone to do my work. I have many professional qualifications. Most require refresher courses if l have not been in practice for a number of...

    R2D2 replied to a thread Antenna Quandry in Antennas
    If all you had was a G5RV, you didn't have nothing.. So I guess anything would be an improvement over that.. Verticals works best when properly installed and grounded, preferably over a salt water marsh. I have a 5BVT that has had 6 owners, not one of them were ever satisfied with it. Forget the tuner route and telling us how great this or that antenna worked.. When the band is open, even just a couple of watts will do something.. The metal shed bothers me as much as anything, no telling what kind of problems it will create. Start out small and work your way up. If you want a vertical, buy yourself a CB radio antenna and modify it for 10 meters..

    I dont have the FT8900, but I think both the transceiver and the mic have a lock function. You indicated that you have performed a reset, but you might want to check those features. Everyone probably knows this, but you can search for a keyword in a .pdf. Ctrl+F opens a search box. Sent from my SM-G973U using Tapatalk

    Greetings. Newbie to the Forum, inactive ham for several years. I am trying to get my hf rig back on the air. I am searching for a good solution to erecting an antenna. My shack is located in a 24x36 metal post frame building near the back of my lot. I don't have trees from which to string a wire antenna (At my old QTH, I had a G5RV strung between two trees and worked the world with it). I have considered a vertical in the center of the metal roof (like a Hustler 6btv). I've also looked at a post about a G7FEK Limited Space Antenna, anchoring one end to my house and the other on a pole near the shack. I'm reading, with interest, about downspout/gutter antennas. I am open to ideas about how I might get on the air, all suggestions welcome and appreciated. 73, W9ROX

    As you're probably aware, as a result of the COVID situation, Foundation practicals are still suspended and RSGB exams can be booked & taken online from home. Since April, we've seen demand for online training skyrocket as the majority of clubs are no longer able to offer classroom training due to COVID. We had 420 people join one of our courses in April, and over 500 in May. Our next free revision course starts this Sunday, and we have over 230 enrolled so far - there's still time to enrol if you, or someone you know, wants to get their amateur radio licence without completing the practicals or having to visit an exam centre. Our course runs for 3 weeks, includes course material, videos, mock tests and live webinars Handy links:
