    Yep, RF is getting into that system. There could be other ways to fix the problem but if you can get the antenna further away from that box that would be good.

    Hi thanks for getting back to me. Unfortunately there are no trees nearby so most of my dipole is wrapped around 3 sides of the house. It runs directly above the bell box - could this be where the RF is being picked up?

    I’ve had that happen before, where is your antenna located in reference to the alarm system ?

    Hi, Just moved in to a new house with a fitted burglar alarm. When I key-up on HF, the alarm goes off. I'd prefer not to permanently disable the alarm as it's quite useful for deterring burglars! I can't find any fuse or isolator switch for it. Can anyone offer any advice?

    You are on the right track. I haven't used a Nano yet but they are on my radar. Testing and tuning with a decent instrument will teach you more about antenna theory and what works versus what does not more than any book. I'm lucky that my job has anything I could want to test antennae. As Hams, we are trusted by the FCC to design our equipment to operate within specified parameters and our reward is an efficient piece of gear that works as it should. I commend you for wanting to do just that,

    If you're getting 60 miles you have about reached out as far as you can. We do have a repeater in my area that is 1600' and will do 75 miles, but there aren't that many out there that high. Height is always your friend, so getting your antenna higher is better than buying one with more gain.

    I'm afraid I can't get the current one up higher than 30 feet. Would I be correct in assuming that something like the Diamond F22A won't help my situation much if I can't raise it?

    Can you go higher with the existing, or replacement antenna? Sounds like it works fairly well now.

    Currently, I have the antenna hung up in a tree with the tip about 30 feet off the ground, the best it can get are repeaters 60 or so miles away. If I used one of these vertical 2 meter antennas, that height would be about 20 feet (as measured from the bottom of the vertical). Would it still be the switch to the Diamond F22A?

    At vhf and up, yes 213 is the better choice. There are better choices than 213 but the only way to be sure is compare specs vs cost and see where it is your wallet cries uncle.

    Deltawhiskey started a thread Handheld Radios New to amateur radio, question about Ft2dr in Yaesu
    Hello, Iím testing on December 7th and expecting to pass tech and general. I picked up a month old ft2dr for cheap, but Iím struggling with SD card issues. I have a new class 4 32gb sandisk that the radio doesnít like as well as a class 10 32gb pny. I have a samsung class 4 8gb that the radio likes, but after backing up the radio the card is not recognized by my windows 7 machine. Iím kinda puzzled on this one, and I donít really want to just buy random cards until I find one that works. Any advice greatly appreciated Sent from my iPhone using Tapatalk

    Whoops, almost forgot that... I'm using a Kennwood TM-281 with no more than 65 watts of power. The three main antennas I'm looking at are the Diamond X2200A, Diamond F22A, and the Tram 1481. I am indeed willing to change the form factor of the antenna if it could yield an improvement. Also, while I'm currently using RG8X, I plan to replace it with RG213. Is this necessary for a 30-50 foot run?

    That antenna is good deal and probably works as well as that form factor can do. You might contact Dr. Ed & group if they have further antenna ideas. Other than that, putting it up higher is probably the best (& only) way to accomplish what you want. But you don't indicate your radio. How much power are you running? And knowing the radio make/model will tell us how good it "hears" ... how senstivie the rcvr is in other words. Both very important factors.

    Currently, I am using a DBJ-1 antenna (like this https://www.ebay.com/itm/DBJ-1-Dual-Band-VHF-UHF-2-meter-70cm-ham-base-antenna-/113516146770) for my VHF radio. It has served me well, but I am looking into upgrading to something a bit better to help me reach more distant repeaters. I don't want to spend more than around $120 on a new antenna. Is there an antenna that will get me better performance for this price point (provided that the height, radio, and location are kept unchanged)? Or am I really best sticking with what I got right now. If $120 isn't enough, how much more would I have to spend to see a real improvement. Any help will be greatly appreciated!

I have operated Radio Fine, with this Toroid temporarily removed. This Toroid addition is not denoted on the schematic.

    I'm Mike, originally from CT, USA but currently living in northwestern VT with my wife and our two pets. I've been playing with radios since before I can remember, but just recently acquired my General license. While not studying for the Extra I enjoy DXing, SWLing, chatting on local (and not so local) repeaters, and messing around with FT-8. I'd love to start getting into more satellite stuff as well. My current rig is the Yaesu FT-991A but I also have the little UV-5R that I bought so many years ago. Anyhoo, it's nice to be here and I hope to find some of you on the air! 73 KC1LUX

    Looking further into your question, I think you need some sort of commercial - type equipment. You could do it if every station had a packet transceiver and CAT capable radios. Maybe a simpler approach would be a better idea, like CTCSS on a single frequency...

    On the surface I want to say no, not in daily operations AFAIK. I do remember a regional emergency band plan that has all the actors pre staged on "their" frequencies, but there was no "Central Scrutinizer" directing traffic to other frequencies. What made you think of this?

    I'm Admin and Moderator on several groups and yes, things can go quiet. I was asked to reply to a comment on one Facebook group and found that there had been one post and two comments since May! And there are plenty of 'one shot' posters on all sorts of groups. They come one, ask the question, get helpful replies but never comment again. I suspect what happens is that they post on several groups and having got the answer on one of them, never bother to come back to the others. This is one of the quieter groups that I frequent.

    How do you mean, please? Are you referring to X.25, and how can that be used in the way I'm asking about, in a manner like a standard telephone switchboard, please? In my scenario, I'm thinking that all operators are using standard gear ... mobile, HT or base radio units, typically connecting to a standard repeater or linked repeater network. How does packet radio fit into that, in order to re-direct traffic to a different repeater system or some simplex route that is transparent to the incoming traffic operator? Apologizing for my ignorance, I'm looking for specific equipment or techniques that can do that, just like a telephone switchboard does.
