    Most, but not all, linking systems are now internet based, mostly because it's convenient, doesn't require a lot of infrastructure and is cost effective. Some repeater systems, however, are still linked using direct radio links. We have a system here that links four repeaters from the Laguna Mountains east of San Diego to the White Tank Mountains just west of Phoenix. They are interconnected with direct UHF links. The system is heavily used by desert dwellers, off-roaders and campers.

    Hi all, New member from Myrtle Beach SC, W2SOC. I like what I have read so far and look forward to reading more and learning much. I mainly do HF SSB with a bit of digi when the mood hits or the bands are poor. Thanks for having me! 73 de W2SOC

    WOW ! That's one heck of a slab of concrete ! Yes , I can see being near the coast would need a good base , but I would of thought guy wires would help even more in your case . I couldn't place a Yagi in my neighborhood . We're on 1/2 acre lots . Now if I was still living on the 12 acre farm where I grew up , it could be a possibility .

    I read on QRZ that a General Operator stayed on Key West during the hurricane and after the main storm had moved northward he got on 40 m to pass traffic between Key West and the main land of the United States for his neighbors to let their love ones know that they survived the hurricane. I believe the ham had Battery Back Up for his power source for the transceiver in his home. The use of a 2 m or 70 cm repeater would be useless for this kind of a disaster considering the small RF footprint / coverage the repeater could only provide ... maybe 25 to 30 miles maximum whereas 20, 40 & 80 m has a range of 500 to 1000 air miles.

    I wonder how well repeaters / Echo Link worked in Puerto Rico after the hurricane. I could be wrong but betting it did not help much. I heard VHF/UHF was used for command and control. Experienced ops went to assist. HF was used for mainland communication Point is you should not rely on infrastructure when chips are down. 99% of reliable comm can be had by HF NVIS. 80 Meters NVIS is easily doable.

    Gentlemen - when I finish installing my 160 T antenna, I'm wondering if I'm going to need to use some sort of measurement eqpt to verify matching and efficiency of the gnd plane as I add more and more pieces of wires and connections to fencing. I've never used antenna analyzer gear, so I don't know whether or not that eqpt can help me verify how much improvement I'm making as I add 'stuff' to the gnd system. I'm just guessing that swr is not the only indicator when improving a gnd system. Am I right or wrong on that. I sure don't want to spend hundred(s) of $ on analyzer if SWR is a sufficient measurement to evaluate performance of my counterpoise and subsequent improvements to it.

    there are more today than there used to be that utilize batteries and solar power, but they are still few and far between and would still be useless for anything other than the range of the individual repeater... with the grid down, there will not be any linking...so grid down, emergency circumstance, HF is still the most viable, if not 100% dependable means of communication...

    probably as well done as most...and should be fine if you are doing as you said and only putting a vertical and maybe hang a dipole or two off of it. My 50' tower is anchored in a concrete block that is 7'x7' by 6' deep. Then again mine is free standing and supports an 8 element hf log periodic. The install is per engineered specs for our wind speeds (near coast hurricane zone) and a larger wind load than I put on it.

    Not altogether correct... There is an increasing trend to make repeaters completely independent of the power grid through the use of solar power. For instance, my club has two repeaters running totally on solar power with back-up batteries for nighttime and days when there is no sun. The system has been in place for several years and functions flawlessly.

    Well , taking the tower down went smoothly . Base of tower is now plum and concreted in to 3'x3' X10" thick bottom . Base of tower sits on 3/4 rebar concreted in a 24" round drum 34 inches high . All told it's sitting in 1500 lbs. of concrete and rebar 48 inches below ground surface . Now I need to work on lightning protection . 3 copper radials away from base to 8 ft. ground rods . Then an entry box for coax with lightning / static arrestors mounted to a copper buss bar which in turn will also have a ground rod connected to it . Does this sound sufficient ?

    I realize this is an old thread, but thought an answer might help someone. I bought the full RT Systems kit, including data cable for my FT2D. I'm glad I did. It uses the cloning interface (mic jack) to send and receive data. The other way is using a microSD card. The microSD is probably the fastest way to transfer data, but the you'll spend far more time making sure your entries are perfect. I haven't purchased the Yaesu branded cable, and don't plan to.

    Hi. I recently purchased this device and have programmed in some of my local repeaters. However, when I check my frequency offsets from channel mode after saving, it has reverted back to zero. I am programming making the settings from frequency mode before saving. Is this the correct sequence, or should all settings be made from channel mode before or after saving? The instructions that came with the device are not clear about this. Also, what name and model device is recommended as an upgrade from this basic one?

    More often than not, I see (SK) in notices online. IF I were you, I'd consider an upgrate to Extra so you can get the callsign before a non-family member does. That's the most fitting tribute one could give. 73 Lloyd

    turns out, my suggestion may not help... I just remembered that I had an old QST copy on the bookshelf here in my office. I looked up how they did it... and they just listed the call sign of all the new silent keys that month...no designation on the call sign itself. What ever you choose to do, as an old man myself, I can tell you, your father would be proud... thanks for thinking of him and his beloved hobby that way.

    never saw anyone do that before, nice way to remember. I do not know that there is any real protocol on that. Maybe check some his old QST magazines and see how the ARRL lists silent keys.

    According to the user manual the radio does not have CTCSS fitted it is only on the TE790A. You can get a retro fit PCB the TSU-5 or you can use the one in this Youtube video https://www.youtube.com/watch?v=HuW0IwkKASU.

    My father, (WD8M), passed away this year, and he was an avid ham radio operator throughout his 60+ years of life. My question is, how would I write his call sign with a silent key abbreviation? Would it be WD8M, SK or WD8M (SK)? If i were to get any sort of memorial jewelry or artwork of his call sign, I would want it to be correctly done. Any response is appreciated, thank you.

    Here it's November '17, I just found this thread and here I am resurrecting an old, dead zombie thread anyway, sorry. :redface-new: So, here goes from the forum noob... While I notice the forum apparently originates out of the United Kingdom, it seems all are welcome. So, in the interests of international goodwill and all that, I formally declare if someone asks me a question I will do my best to answer it or at least point you in a direction. That is because after 21 years in, I still remember being a noob and how it can be intimidating sometimes. Now, having only had experience with ham radio in North America I may not be the best one to ask about things specific to a different global area. Like for example, without looking it up I couldn't tell you how the RSGB has its license class system set up, or how reciprocal agreements between Asia and Africa work. But, the general knowledge items I can probably be helpful with. I would like to think I'm not above any question but if it's patently obvious...

    Hi Everyone I have just bought a lovely TS 790e and I am trying to get on the local repeaters, I have managed to work out the offset setting but trying to get the tone burst code is not working. I press the F key then the Tone button to give me the selection of tones. I think I am right on 2mtrs and 70cm I am looking for a tone burst of 1750hz. but I can only find 1738hz and the next one up is 1799hz. Can anyone help me with the correct settings. Many thanks Brian
