    Despite protestations to the contrary, latitude makes a difference but that is not a reason not to try. Keep trying!

    Youtube is hopeless for learning. There are so many truly awful ones, and they're usually incomplete at best, but at worst, they confuse - because you rarely can see exactly what they are doing, and your own installation, using a computer will look totally different. Drop down boxes will have different driver details, or different hardware, so available options are wrong, and very, very rarely are any critical points explained - they are just assumed to be how it is. Books have to generalise, but normally deal with specific building blocks and explaining the components, and they don't deal with equipment specifics - Youtube view it from the operation end, so what you need is underpinning knowledge then perhaps a youtube over-view? However, don't forget that the on-line info is NOT always video - there are some very good information sites, and of course the manufacturers have good info sources. The worst, I always think is youtube, where opinion is always top of the pile. I use youtube to find quick solutions...

    Thanks for coming back with the info. Unfortunately, I agree with all you have said but I (being old and old school) don't really like reading for any length of time on a computer or a tablet. Youtubes are good but all the ones I have found seem to start out over my head and move up from there:confused:. Thanks again.

    I know exactly what you mean, being perhaps a similar age (licence originally in 80) - but the book route is NOT possible for reasons other than the obvious one. Authors are not writing books because they cannot make any money. I've ben involved with specialist books for quite a few years and mine died a speedy death and never recouped production cost - so the 1200 odd books I sold never made me a penny. Libraries were always good for a run but they don't buy them any more. One of my friends, however was a prolific author, and I bought his books when I was a teenager starting out, and ever couple of years there was a new edition - but suddenly, about ten years ago it stopped dead. His publisher, with his excellent track record wanted a guarantee of 15,000 sales or no money, and his new books were doing around 10,000 - so he was dumped. Here in the UK there is a healthy technical press range of books that sell on this subject (theatre stuff - lighting, sound etc) but the authors get a tiny payment, so they're...

    Yeah, I don't do much 20 meters, but 40 has been in pitiful condition for the past couple of weeks. Seems to be coming back around though. Don't give up on it, the bands are just like that... up and down often. Like the previous poster mentioned, there's a number of places on the web that you can use to check how propagation is at any point in time. Good luck. Brian Sent from my SM-G950U using Tapatalk

    I am just getting back into amateur radio after a very long (@30 years) absence and much has changed. I would really like to learn more about software defined radio and prefer to learn by reading books. Can you suggest a good book on sdr for a complete newbie...something like SDR for Dummies (no such thing exists unfortunately). The two that seem closest to what I need are "Software defined radio: for amateur radio operators and short wave listeners" and "The hobbyists guide to RTL-SDR". Would you recommend one of these or perhaps something I haven't seen yet? Thanks for any advise you can give. Jim KE4RM 73

    Bands can be up and down. You can check here http://www.bandconditions.com to see which are open. I don’t run more than 20W on JT65 or 30W on FT8. DX Heat is also a good site to see where the activity is. On the data modes you can use PSK Reporter or Ham Spots to see how well you are doing. For phone, you could check th3 many SDR sites and see if you are showing up on their waterfalls. With regards to power, I’ve never ran more than 100W.

    Hi, I'm in Northern Ireland and have an Icom 706MKII and seem to be able to make zero contacts on 20/40m. I've had some success on digimodes which tells me something is going out. My power meter peeks at about 60w on 20m and 100W on 40m when making calls. Does 100w not cut it these days? I hear people talking about their 2KW rigs. Any advice and tips would be appreciated. I'm trying throughout the day. I have a 20m dipole, with ladder line, probably 8m of feeder cable. Ta,

    My RTL-SDR provides raw I/Q signal pairs as the data format, at a sample rate of 2.4MSPS on each channel (the 2 channels being the I and Q signals). Now for further processing I want to first get the entire band "at my fingertips" which means converting it into a single channel real-valued (not I/Q) signal. This one channel will of course represent double the bandwidth (4.8MSPS). I've recorded a wave file from SDRSharp, and it has the I/Q data stored as a stereo WAV file. The output of the conversion should be a mono channel WAV file, that has combined the I/Q channels and doubled the bandwidth. What is the simplest way to do this conversion? Is there software already "in the wild" that will do this conversion for me, and if not, what is the easiest method to do this conversion?

    Louis Varney was a clever fella - He was an officer in the Royal Signals during WW2 and specialised in antennas for direction finding and interception. He came from Essex (Colchester or Chelmsford, I think) and did a talk at the Lowestoft Radio club back in the 80s when I was first licensed. He spent a lot of time talking with the old boys who all seemed to have been doing things with radio in the war - very much a closed shop radio was back then! They ALL had G5RVs in the gardens, because people thought they were washing lines. Hams kept very quiet back then because they interfered with TV so much. You had to be brave to advertise what you did as a hobby.

    I have an X50 but it's at the top of my tower. If memory serves the threads are 1/4"- 23 ( what ever the fine thread pitch is, not 1/4 - 20). I'd just take the antenna with you to the hardware store and match it. Sent from my SM-G950U using Tapatalk

    Yaesu FT101ZD + Daiwa CN419 manual ATU, then Kenwood TS-930S-AT, with built in auto ATU. Add 1 x 1/2 size G5RV, fed with around 30 feet of RG58 to the PL239 at the bottom of the ladder. Result? No issues, no burnt out radios, no need to tune at all on 20m, and either ATU coped happily on 10, 15, 20m. Much DX done with no problems. I will put one up again just as soon as my son moves out in the summer and I get my shack back. And yes, I've also gone the dipole, balu, co-ax route, but it didn't fare any better than the G5RV, so I'm sticking with it. You probably won't accept this as 'proving you wrong', 6m, but I can only offer my personal experiences as evidence that the G5RV CAN work very nicely indeed.

    You're welcome. The damage done to your transceiver, is already done.. Here is a short story for you - I bought a brand new Kenwood TS 590s in the fall of 2011 after listening to the whining / complaining of the local club members - at a field days site. Each expert operator had their own opinion on what was good and what their transceiver was - in their opinion. No one wanted to let others operate their station. I said screw it and bought my own HF radio. First year, life was good. I made lot's of contacts and I operated about 16 hours of the contest with no issues. Second year, the club decided to save a couple of bucks and they bought one of those cheap Harbor Freight gasoline generators.

    What you are looking for is called an Off-Center Fed Antenna. Not all Off Center Fed antennas are equal. The good ones cost considerably more then the cheaper ones. The reason for the extra expense is due to the fact that it takes special torroids that must be tested before the balun is built is necessary for them to be resonant on more then a couple of bands. Look at the web site for the Hy-Power Antenna company. Their 80m Off Center fed antenna would do the trick. You will need to get it up as high as possible, 30 - 40' minimum. You will also need to use multiple supports - so you can bend it in the shape of a letter L. Don't worry about how far away from your house it is - that is the purpose of good / low loss coax. 150' of LMR 400 or Belden 9913 has negligible loss on 80 / 40 / 20 meters. You will soon discover that it will also work on 17 meters, 10 meters, 6 meters, 2 meters, 70 cm - without a antenna tuner...

    Thank you for the advise. I appreciate all advise. I had already down loaded the advance manual. These manuals are written for the those that the manufacture believe to already know the language. There is no glossary that explains what words mean. Had I known what V/M was VFO/Memory it may have been easier. I have been picking thru the manual and reading threads and I know more today than I did yesterday. I will know more tomorrow than I do today. I got the Yaesu programming software loaded and working today. Did a few frequency programing tests and up loaded it to my radio and that seems to work good. Then I went back to the manuals and figured how to program it by hand. I'm good till the next question! Thanks for the help. This is a great community with so many willing to help. Hope to be chatting with some of you on air in a few weeks. Until then, I believe its, 73's?

    Hi Bill, I tried the programming app from Yaesu a few days ago and could not get it to connect it to my radio. I have read here there are others here that have the same issue. However.......I tried again this morning and picked thru it a little bit more. For those of you that did what I did by just going to the "Communications" then "Comport settings" and trying to get it to connect.....that does not work. There is a process that needs to be followed. Go "Communications" then "Get Data from the FT-70D" That brings up a list of steps on how to get your radio to connect thru the COM PORT. Follow it to the letter and it should connect and up load the setting your have in your radio. When your ready, save the file, Then go to "Communications" to "Send Data to FT-70D" and follow the steps again. Easy Peazy. I hope this may help other newbies like me get connected. It really is easier than the manual programming. Archie

    Archie, been there, done that, lost my hair. I strongly suggest you go ahead and get the programming package and cable for your radio. The programming features are almost endless and you'll be so much better off with good software that lets you look and edit the spreadsheet. Good luck with the upcoming test. Watch for fatigue and frustration then take a break and come back to it later. Bill (Auld Willy) KK4LYQ
