    Ok I found the software for A19 and T-650UV, though I cannot get the software working for my radio. But if any other are looking for software for this radio, these are the software directly from the manufacturer. Download: A19 Download: T-650UV

    I don't have any experience with dipoles other than those I've made myself - which have all worked just like the antenna books say they will if they're installed correctly. Never made a G5RV; just made dipoles for the bands I was interested in. Depends a lot on available real estate with lots of trees the right height.

    The only thing that can cause a reflection is an impedance discontinuity, e.g. a change in the Z0 of the feedline. Since you are not changing Z0, theoretically there will be no reflections. In the real world, reflections will be negligible.

    If you want to try building one take a look in the VHF UHF MANUAL 4TH EDITION page 8.15 or in this archive https://archive.org/details/Vhf-uhfManual page 9.16 Cheers Mark

    Are you listening to FM or USB? Plugging in even a rubbish antenna to a radio set to AM or USB brings up extra noise. Static means crackles - distant lightning, so random impulse noise. Hiss is well, hiss. Attaching an antenna to a radio set to FM which is hissing wild with squelch open won't get any louder. This antenna NEEDS a ground plane to become efficient. It's designed with a coil in the base to fool the radio into thinking it has a wave attached. The ground plane is part of the aerial, so as you haven't got one, to make it function you need at least a few long conductive elements connected to the screen. If it's sitting virtually on the ground, then an earth spike as close to the antenna will make it work much better - but if you are listening FM, then you might just have nobody around to hear. More info on what you are doing is needed.

    I've just read up on the WSPRlite and it seems to be pretty much the same as the WSPR beacon which I operate. Are you expecting to operate on multiple bands or just one? If it's only on one then ime you'll get more spots on 20m than other bands. It would be feasible to make a full sized 1/4 wave vertical for 20m using a fishing pole. I just use a homebrew loaded whip and last year got regular spots from Australia but band conditions are no longer that good and UK-USA seems to be about it for me now. 200mw almost certainly won't operate an autotuner but there are QRP manual tuner designs so exploring that option may offer a solution. I built an Emtech ZM2 kit and that would probably operate on 200mw (you need to have enough power to light a led which is used to detect a good match). I looked and they don't seem to be on sale any more but they may pop up on ebay or at ham rallies. A full sized vertical or dipole for the band you want to operate would remove the need for any tuner and give you a pretty...

    You'd do better to fit it with ground planes rather than just run a length of wire into a ground spike. That said if the signals are present and reasonably strong you'll at least know there is something there - if all you are hearing is noise then maybe you are not using the correct mode or maybe there is nothing on the frequency you are monitoring. What are you expecting to receive and from where? What receiver are you using?

    Residing in East Anglia, retired from Metropolitan Police Force back in 1989 and prior to that served in Royal Navy for 10 years. Operate CW only on HF (G4FPK) but lately my CW receive speed is rather lagging, my excuse for that is the fact that I'm approaching my 82nd birthday!

    Check the coaxial cable. If you have more than 20' of coax, that could be your problem. The signal coming from the antenna just isn't enough to make it through more than a few metres of RG58. Receiver sensitivity will also play a part. A second antenna will show this. Anyway, use a SWR meter to see if you at least have 50Ω...

    I have a Radiall-larsen nmo 27 mobile antenna set up on a little stand in my yard. I tried grounding it a bit by attaching a wire to the mount and then to the ground. When I unplug the antenna, the radio makes the same noise as when its plugged in. What should I do?

    Not sure what the other radio is yet, but he said it is going serve me better, comes with a lot of other stuff most of it he is just giving me. So I can't complain. But he did say the one i bought (the 1900r) would probaly be better for someone else's setup then what he is giving me. So I guess I will ebay it unless someone else could maker better use of it wanted to shoot me an offer. It's new in box.

    Depends on which "HF dipole from MFJ" you're talking about. Why not make your own, feed it with parallel line (300 ohm old TV-type twin lead), window line or ladder line. You'll want a tuner as well.

    I agree, a pattern is a pattern no matter if its RX or TX. An example of this would be watching for a signal peak while rotation a yagi beam indicating you had it pointing at the station of interest. In fact, you can plot the radiation pattern of any antenna on a map if you know the general location of the stations you are working. Every time you work someone, mark it on a map and record the signal strength and over time you will begin to see the pattern take shape by the locations and directions the majority of stations are in. Another example is rotating a TV antenna for best picture reception (telling my age here) 1

    You won't have the ability to use it? It's not the most complicated radio in the world. What is the other radio - we'll happily tell you which we'd rather have out of the two!

    I would have to disagre with PMH on the pattern being transmit but not receive. Antennas will have the same pattern on both transmit and receive. I will welcome any logical argument with data to the contrary. Joe KA9UCN

    Dipoles can have several orientations: Horizontal, V, inverted V, L, etc. This affects transmission rather than reception, so whatever best suits the space you have. My Comet H422 is in a V, as this suits my space, is less directional, and can be a little close to the ground than if it were horizontal. Kind regards,

    Mount it anyway you can, but for better Omni directional coverage, put it up as an inverted V with the feedpoint higher than the ends and it will c over all compass directions better.

    An angle will skewer the pattern slightly but not of any real significance. It will effect performance some what in that it will be on par with the dipole average rater than one placed at the higher or lower mounting point. You had mentioned that you might use magnetic wire from a transformer. This will work and although performance will be as good as other types of wire. For durability at a minimal cost I would consider using an old extension cord wire. Strip it into separate conductors and solder or even tie them together to obtain the length needed. An extension cord is constructed of stranded wire that is designed to be flexible. If it is to be attached to any structure that can move in the wind. Consider a pulley and counter weight. Joe KA9UCN

    So let me start off as saying I am new to this. Completely new. I have researched a class and all so I can take the testing, but this all came about an an impulse buy from another hobbyist. I purchased a yaesu ft-1900r. It's new in the box and I believe I may not have the ability to use it. So where would i go if i wanted to sell it. Someone offered me a different unit all setup I can start with instead really cheap so I really don't need the 1900 now.
