Thank you for such a comprehensive post. a) I imported the 2 meter national simplex entry, 146.520, from CHIRP, US Calling Frequencies. The parameters looked like the manual ones I entered that also worked for both receive and transmit. I confirmed the frequency for transmit was the same for both transmit and receive. b) I imported the following 2 meter repeaters into CHIRP from the Repeater Book which are the 2 closest repeaters to my back yard in Dupage County. The parameters looked like the manual ones I entered and behaved the same. I confirmed the TX frequency was 0.6 MHz lower both RX frequencies. They show as associated with channels 1 and 2, respectively. Both have WIDE for menu 5. CTSS tone = 107.2. 145.4300 -0.6 MHz 107.2 Downers Grove Dupage IL W9DUP OPEN 145.3100 -0.6 MHz 107.2 Wheaton Dupage IL W9CCU OPEN c) The battery says 7.4 volt/1800mAh/13.32 wh, Menu 2, HIGH/LOW, Transmit Power, parameter and it says HIGH. d) Did that interesting experiment setting up radio 1 to RX frequency and radio 2 for TX frequency, 0.6Mhz less. No transmission was received at all. Even after finding a position where I found a conversation. Same results after swapping them. Did the same experiment with other repeater and swapped. Same results. Experiment is helpful and seems to support my thinking. I’m really thinking now this Baofeng UV-5R might be too weak for my purposes. People that have them and recommended them are from rural areas. I'm in a west Chicago suburb, a different situation. Here's additional actions which seems to support this thinking. The 2 times I’ve had any success (one before new antenna and one after) is when I hear another Ham on the repeater, turn the radio/walk around, until I hear him well, transmit, and Ham says he hears me but “low volume.” Then I walk around more and he says, I don’t know what you did but I'm hearing you better. In both cases they could read my call sign back to me. Most other cases, HAM moderator of lunch session on W9DUP said heard only static for one radio signing in. When another person and I tried to receive/transmit on quiet repeater using my 2 radios in my backyard, we never heard a thing. I’m guessing because we both didn’t know a good place to stand without receiving another Ham already on the repeater. So, in net, this Baofeng UV-5R seems too weak for my purposes. Any recommendations for another handheld radio for these purposes would be appreciated. 1) Trying to set up communication with people in Neighborhood Watch 2) Area is about 20 blocks of houses, one side of a street, in a 4 x 5 block area. 3) Most people would be outside reporting neighborhood issues (like weather damage) across the area. So very portable hand-held radios would be needed. 4) Handhelds should be able to communicate with each other both outside and inside houses in the area. (If not, might have to get larger radios for people who spend more time to communicate with the outdoor handhelds) 5) Handhelds should be able to use Simplex and Repeaters especially since anybody might be monitoring weather reports. 6) Handhelds should geared to short learning curves after passing Technician exam (VHF/UH FM?) 7) Low technical support solutions would be preferred. Once again, any suggests for handheld radios for above use would be appreciated. Thank you.
