    I want to talk 69.9 miles in every direction but am a realist.   10 would be nice.   It's a metal roof with a rack made of aluminum that gets items like Thule pods, bikes and the occasional canoe carried up there.   I have 13" of clearance to get in my garage, hence the shorter antennas mentioned.

    Nothing is standard. It can have software ADP depending on the flash code of the radio. Q667 was the Software ADP option. You really need to run the flash code from the radio you are looking at to determine which options it has. I have multiple XTS portables that have no secure in the flash code. 

    So naturally I looked at Kemp as well as ebay which begs the question,  if buying an XTL 5000 or 2500 or whatever model from ebay how would I know the flashcode to determine if it does ADP encryption or if it does p25 or to determine frequency range?  Some sellers will know and with some it's a gamble?

    I like radios.  Always have.  Will spend hours pecking away at my phone on this website because of it.  I own a business and the idea of encrypted digital voice or at least digital voice alone (DMR) with a repeater on the building,  a mobile in the truck and PERHAPS a couple of handhelds would be pretty neat.  I'm learning from you all if/how to best do this. 

    Digital interests me because most people (maybe I'm wrong on this) listening on their analog only radios will only hear the machine gun buzz of a digital transmission,  which I like the idea of.

    But I also like listening to the analog frequencies as well, so that's why I have a cheap dual band mobile at my disposal.

    I know very little about the intricacies of P25 vs DMR vs YSF vs WIRESX so that's why I'm here asking questions.   

    This might turn into a boxers vs briefs or Chevy vs Ford answer, but is one digital voice mode more user friendly and easier to program/obtain/work with, than another?

    If you don't know what the band range of your radio is, the 4th character in the model number from the left will designate the band range. "K" for VHF 138-174 MHz, "Q" 380-470 MHz, "S" 450-520 MHz, "U" 700/800 MHz, and "W" for 900 MHz. 

    The channel capacity for the XTL5000 is 1,000 channel. The flashcode will tell you the feature set for that radio such as digital capable or analog only, conventional or Trunking Smartnet or Smartzone, and bunch of more features.

    So is it possible to have a radio that does digital and analog, dual mode type use?  Or is it only possible to do one or the other?

    YES.. although as mentioned, the XTL comes in EITHER a VHF model or a UHF model.  I have several XTL5000 UHF models and they are programmed with all GMRS channels, a dozen or so GMRS repeaters, a dozen or so more H.A.M. repeaters, as well as all of my business/LMR encrypted channels.

    When you apply for your LMR/Business license you can choose to get UHF freqs, VHF freqs, or a combination of both.

    Giggity.   Muchos gracias.

    If I recall tree last time I was on the fcc website I had thoughts of monkeys doing things to footballs. 

    I'll give it the old college try to find a freq coordinator.   

    Does the xtl5000 have the capability to be used on multiple frequencies or does one only program it to the lmr frequency assigned to the business?  

  12. Keeping tones private

    If by "private" you mean, "no one else can use the repeater" (or at least "someone needs the non-standard tone to use the repeater"), sure.

    If by "private" you actually mean PRIVATE, like no one else can hear you, that's absolutely not the case.  Anyone listening to the repeater with squelch tones turned off can hear everything.

    But you knew that, right?

    Keep in mind that someone doesn't need your secret tone to jam your repeater, either.

    See that's where my lack of experience shows.   I thought they'd need the tones to key up the repeater & jam it.  I guess that's where the wifi switch can kill the repeater if someone tries jamming it.

    Maybe I'm expecting the worse out of people but still like to know how to counteract these things if they happen. 

    Thx for all the shared experience here.

    Question the the repeater experts.   How do I keep people from scanning my personal repeater tones and gaining access?   I do not own one yet but am looking at either a gr1225 or vxr=7000 but if other repeaters are more secure I'd welcome experienced suggestions. 

  19. using VHF repeater antenna with a UHF repeater

    in Technical Discussion

    Posted

    I have the possibility of using an old VHF antenna that's up high on a water tower but want to test it to see if it would work for GMRS.  Is this a definite no it won't work or do you guys with repeater/tower experience think it would be worth trying my small mobile radio at the base of the water tower to see if the SWR is crazy high?  I spoke with the 3rd party company that does comm work in this tower and he said that antenna was put up there before his time and he doesn't know what type of antenna it is.  He said I could hook my mobile radio and an SWR meter on the input side of the duplexer and test that way.  Does that make sense?  Is that possible?  Does that mean to disconnect the antenna coax on the duplexer where it says "antenna" and hook my mobile radio up there to test?

    For obvious liability reasons they don't want me climbing to the top of the tower but this is the closest I've been to finding an actual good elevation site for a repeater.

    Another related question.  If there are multiple antennas on the top of this water tower, and I know which hardline I'm able to tie into at the ground, how does a guy/gal test which antenna that coax is going to?  

  21. Removing/replacing bent tower section

    in Technical Discussion

    Posted

    I'll preface this by saying I have not gotten a close look at this tower.  However, I recently noticed an area tower approximately 50 feet tall that has a 3 element beam antenna on the top.

    Said tower has twisted and bent in at least (and I think only) in one place, leaving the beam antenna resting against the tree limbs near the tower 

    Has anyone encountered something similar?  How would a team of people go about repairing the bent section?  My understanding is those beam antennas can weigh between 40 - 60 pounds, if I'm not mistaken?

  25. Burying coax

    in Technical Discussion

    Posted

    I did a brief search and didn't see anything but please direct me to the topic if it has been covered.

    Is it generally unacceptable to bury coax from an antenna to the house/structure where a radio or repeater would be located?

    The pole with the antenna would be about 20 yards from the garage and 10 yards from a power line.
