    That's very strange, here it is the other way around - multiple grounds is discouraged, because extending the equipotential area usually means circulating currents - in fact, if you put a small worksop in your garden, and for good grounding fit an earth (ground) rod, then the armoured cable from the main buildings must NOT be connected to the workshop ground - our regs require that earth (ground) path to be broken for 'safety'. Interesting how different jurisdictions apply very different rules.

    Probably also worth saying that SSB speech quality is extremely variable, and while I can easily understand it, even if at the wrong pitch, my wife cannot make out anything at all - "what did he say?" being a common question. Its similar on things like airband with military pilots and masks - you have the processed audio from a small microphone inside a hard container over the mouth - it's not exactly the BBC in quality, before it makes the journey to your receiver. We are now getting the same issue on digital modes, speech is mangled - to a small or greater degree, but your ear soon adapts.

    As Paulears said in his first reply, LSB below 10 MHz, USB above. As far as time of day, these days that's difficult to predict, but 40M (7 MHz) should be pretty good listening in the evenings. Remember, this is 7 MHz. Is that below or above 10 MHz. So do you listen on USB or LSB? After a while it becomes natural.

    Forgot to ask. When trying to find ham broadcasts you set to narrow AM and turn on UBS or LBS and scan either above or below 10MHZ? Is the evening better for listening to hams? Just getting to orient myself and want to do it right rather than waste my evenings. Don

    Thanks everyone for the great support. I'm reviving this thread as I finally got around to working on that antenna (got slowed down by a new baby boy :pride:). I've decided to do the right thing and I just drove an 8ft rod into the ground so that I can run a copper wire outside the house from the antenna mast to the rod. I also got a lightning arrester that I will keep outside the house as well and connect to the same rod. WA9WVX, do you mean that I should also connect my AC ground to the new ground rod? Another question: I have that second coax that goes from my shack to the outside near the new ground rod. When I won't be using my roof antenna, would it not be a good idea to connect the antenna coax to the second coax and connect the center of that second coax to the ground rod? This way everything would be grounded. What do you think?

    Sorry - I thought from memory the radio had two speeds, but I've realised it's switched in MegaHertz bands, the just KHz on the dial. Just try to set the usb or lsb switches then tweak carefully on the tuner knob.

    Thanks for the information. Usually I have been listening to some stations I like on SW when I encounter the voice characteristics I noted. I did not know to also switch to narrow AM when on the LSB or USB. Did not also know about tuning speed. Could you explain more about that? Again thanks. REgards, Don

    Thanks, but it is not very often I get this warning and I visit many plain http pages where I do not get it, so it must go deeper than that. Richard Stalmann never browses online, now, I am not that paranoid, but I understand him very well. I apologize, if there is anything wrong with my response.

    Loads of pages are http rather than https and never visiting one is crazy. Have a read up about what it means. It is just an indication that somebody could read the two way data which could compromise your security if you included your bank details passwords and sensitive data. Reading a bit of useful info from a university site on datacoms is not a security issue. The warning just reminds you that a credit card could be done better. There are millions of websites that are older and simpler and still use it. Modern browsers and protection software warn you because we rarely read the url bar and the warning helps YOU decide. Going off to another less useful site is plain silly!

    Thanks a lot for your info. With the university pages I get a message that the connection is insecure, but I will look up some FT8 software somewhere. I hear it regularly on 28075 and when I tried to decode trying different modes, all I got was some kind garbage in the form of scrolling characters... N.

    paulears replied to a thread AM Qulaity of Voices/Hams? in Bands & Modes
    The HF bands usually use LSB below 10MHz and USB above it, note that 10000KHz is 10MHz and 10000MHz is of course microwaves with dishes��. Maybe your SSB function isn't working, but apart from broadcast, all communications is side band and sound weird listened to on AM. Do you have a filter that needs to be switched in to narrow the band? Certainly you won't hear AM on ham, aviation or marine channels. The USB/LSB setting needs very careful tuning to turn the mickey mouse sound back into audio, but it's definitely SSB. Maybe your tuning speed is set too high, because we're talking just a few Hertz either way to resolve it and a tuning step too wide can't get you onto exactly the right frequency.

    I am new to this so if it is a dumb question, my apologies. As I said I am new and when going through the from 2000 to 10000 Mhz each night I quite often run into voices that are garbled as if some one is talking with their mouth partially full. It seems to be a conversation with someone but I can never make out many words. I thought this was probably one have talking to another, so I set the radio (R1000 Kenwood) to LSB to see if that would improve things, it did not. I then switched to USB, same problem. My thinking was that you heard hams on one of these two bands. No sometimes, in addition to shortwave bands coming in I actually hear two hams discussing world events, in a clear tone. First is there a reason for the garbled voices that I can fix, and two why are hams coming in clear on just short wave and few on the SSBs. Can some one orient me on these things as to what is going on. Thanks FOlks, Don

    Hi Travis - every Christmas there's one local house near here where the owner has not spared much expense in creating a synched light show. As you drive onto the short street (sort of a long cul-de-sac), there's a sign advising you to tune to 88.1 or 88.3 MHz. And right across the street is a "Toys for Tots" donation station and coffee. Provides a great show most of the time.

    IIRC, anything above ridge height technically requires planning permission. That's not practical to enforce and I guess it would depend on your local planning authority as to what they'll allow. At my previous house, I had a 16 element beam for 2m, a Slim Jim and a vertical for 10 and CB. The council were informed by someone, they came, took a look and said OK, I could keep them without applying for permission, but I should have at least asked them. A year later I applied for permission to put up a 2 element HF triband beam. It took a month or two but I got the permission with no problems. When I moved to this house 30 years ago, I first asked the planning department for general guidance. They asked me what I had in mind. I said a small 2m beam (about the same size as a large-ish TV aerial) with a small vertical antenna (Slim Jim) above that. A vertical for 10m at the corner of the house, and a 25' pole at the end of the garden to take one end of a long wire or G5RV. They weren't worried as long as a)...

    Hmm, sorry guys but I never got any email notifications, my fault as I probably did not check the box. However since posting the question a lot has changed. Indeed I am based in the UK and since then I have got into ham radio. I have recently passed my Foundation licence and my call sign is M6OOA. As for the original question I decided to buy simple PMR radios which did the job. Of course I have moved on since then and now have an Icom 7300 HF rig and an Icom 2730 2m/70cm mobile rig :)

    first post here, I did some searching and could not find anything on this, if there is a good thread please point me in the right direction. I could not find the key words to find it. I have a Buddie Pole antenna and a RigExpert, so when I set up my antenna I can tune it in pretty well. I am finding that if I leave it alone for a few days ( just standing there) I will come back and find the SWR has changed and I need to adjust it for the best SWR. Is this normal? How is this handled in fixed antenna? If I have a tuner (which I do in my KX2) do I need to fine tue the antenna each time? what are the downsides if I do not?

    Sounds like FT8. Fldigi can't decode that. See https://physics.princeton.edu/pulsar/k1jt/wsjtx.html Scroll down to the bottom to get the newest "rc3" release. Please be advised that your computer clock must be accurate to within about a second of the correct time. https://time.is/

    Several years ago, Motorola-Solutions, Inc. Marketing Department changed the different band model numbers so these people would know what Model Number they were talking about. This didn't make a bit of sense to Engineering as we had the Best break down that everyone knew, you would have had to be an idiot (Marketing personnel) not to understand the previous Model Numbers. But Marketing made their own Model Numbers and that's what we're stuck with. I'm guessing the two individual Model Numbers will start with a H03 for VHF and H04 for UHF and that's the Best I can do.

    Hi, I am just getting back into Ham Radio after 25 years. I posted earlier about a IC 745 that I just plugged in from being dormant for for that period. Needless to say it had issues like no screen and a small amount of smoke coming out the bottom. Contacted a repair shop and they were a bit discouraging about repairing it but said they would give it a try. Thought perhaps buying a used newer rig might be the way to go, so started looking. I ran across a Icom 756 PROll that looks nice about a hour and a half away. The price seemed fair at $650 with 2 mikes. From what I have read the big issue is the fact that Icom no longer has the screen available and they all fail eventually rendering the unit kinda kaput. Is it possible to control this radio via external software if the screen quits?
