  1. That defies the odds big time, hitting something that far away without seeing it first. Probably time to make an appointment with your optometrist, or just be more careful driving next time! (Sorry, couldn’t resist.) ...

  2. I would not use that mount and damage your paint in anyway. That'll turn into a rust spot.

  3. Such is the case Admiral. I did in fact miss it. Thank you for the clarification.

    Thank you so much WRHS965. I have downloaded the iOS app. I will work on learning it.

    GMRS trunking system?

    I've thought of doing this but don't have any LTR capable radios. It would be set up as a single channel LTR system and with the pulse turned off. I have heard of exactly this being done to thwart repeater jammers and unauthorized users. I've thwarted a well known jammer in the past by using DCS/DPL instead of CTCSS/PL. The jammer in this case had antiquated radios that only had CTCSS/PL capability and no DCS/DPL capability. He also didn't have a clue about DCS/DPL. I've heard him screaming on the air about being unable to get into my repeater. He was continually p!$$ed about not being able to get into the repeater after trying almost every CTCSS/PL tone. I've heard of DPL also being referred to as "Definitely Prevents Losers" LOL. This won't work today with most modern radios having DCS/DPL in addition to CTCSS/PL.

  6. EDIT: You have one of the more complex requirements. This image is how you should set up CHIRP... http://fiveguysracing.com/marc/HAM-GMRS/SplitTone.JPG Or this if you want to hear everyone, not just repeater traffic... http://fiveguysracing.com/marc/HAM-GMRS/SplitTone2.JPG I can't speak about what your radio can or can't do, but Chirp is pretty straight forward. Use the image below as a reference for what the general meanings are. Start here... https://chirp.danplanet.com/projects/chirp/wiki/MemoryEditorColumns LOC is the channel location, aka what memory slot. Frequency is the simplex frequency of the channel you want to use. If it is a repeater frequency, you enter the repeater output frequency, which is what you will be listening to. Name is just that. Pick a name that give you an idea of what channel you're on. Now... the tone mode can be a little confusing for people. There are a few options to pic from, but until you get used to the radio and software, I would not set the tone mode for anything unless needed for a repeater. The tone mode that is most commonly used is 'Tone', which your radio transmits sub-audible tones to open the squelch of the radio/repeater receiving your signal. If you look at my example below, I have Tone set on the repeater memories. But I also have TSQL on two repeater memories. That function transmits a tone to open the repeater and my squelch only opens when the repeater transmits that same tone. The reason I have that set up is because there are two repeaters near me, using the same frequency pairs, but they use different tones. So, by using TSQL, I know when I hear a signal, it is coming from one specific repeater. So, you populate a value in the Tone column if you what to trip a repeater, but hear everyone. Use the TSQL column if you only want to here people or machines using a tone when they transmit. (Note, there is a Cross mode. That is for radios that support transmitting one tone to open a repeater [for example], but having another tone open the squelch on their radio. I would suggest spending some significant time researching how that works before you mess with it.) You will also notice that I have two memories configured for DTCS, at the very bottom. This mode is commonly called Digital Code Squelching. It is just another squelch type. Most repeater owners don't use this method. It is most common on simplex channels. It can also be insanely complex. You can have DTCS or Split DTCS, transmitting one code and your squelch opens with another code. Than you can reverse the code sequence on none, one, either or both. I would suggest spending some significant time researching how that works before you mess with it. If you look at the image below, you will see which tone column is associated with what tone mode. That should help understand those. Just ignore DTCS RX Code, DTCS Pol, and Cross Mode until you learn about how those items work. The duplex mode is going to be None for the GMRS and FRS channels, unless you are programming a GMRS repeater pair. Then it will be a Plus (+). If you are programming a repeater pair and select plus, the software should automatically select the proper frequency offset, based on the starting receive frequency. If it doesn't, you should enter 5 MHz (5.000000). This automatically changes your transmit frequency, when you press the PTT, to the repeater's input frequency. For Mode, you can use FM for everything except the FRS channels 8 through 14. Those must be set to Narrow FM or NFM. Also, if you cannot program your transmitter to 0.5 watts or if your radio has a detachable antenna, per the law, you are not allowed to transmit on those frequencies. My radio doesn't go any lower than 1 watt and has a detachable/external antenna. So, I have them programed for receive purposes only. Power and Skip should be pretty obvious. Anyway, hope that helps. http://fiveguysracing.com/marc/HAM-GMRS/ChirpProgram.JPG
