    SDS200 volume issue

    I was just going to post this. I did buy this exact ground isolater, connected It between the ext spkr jack and aux input, and have been testing it for a week. So far it has not failed, and we have had plenty of cold mornings where it would have failed otherwise. $10 solution. Have not tested...

    SDS200 volume issue

    Update on my cold weather audio muted problem - Now that winter is here, I have the problem most every morning first thing in my car when I turn on the SDS 200. In my configuration, I have the car’s aux audio always plugged into the line out in the back. When it fails, I have found that...

    SDS200 volume issue

    Update: This weekend I was at a place where it was much colder in the morning and the SDS 200 in my car would fail (no audio) when first turned on every time (sometimes the first several times). At the time the temperature of the case was 55 F or less. During the past several months at home I...

    SDS200 volume issue

    Yes! I have the same exact problem with my 200. About one in ten times I turn it on it is completely muted. So far a power cycle always fixes it. My filters are always set to Global, that has never changed. Maybe a bug in the audio mute firmware for the hum problem? (I don’t need to use that...

    SVRCS Question Thread

    Fallback Plan? Anybody know the fallback plan/frequencies for SVRCS when the system is down? There have been issues today with bad reception in areas and I noticed big gaps in traffic, so I wondered if they went someplace else in the meantime. (Maybe some fixed conventional repeaters in the 700...

    SDS100 your likes / dislikes

    Keypad lock I'll start with the likes: almost everything! The SVRCS system I listen to in south SF bay area comes in like a champ, MUCH better than my 436. Love the display - I use white on black and have added RSSI to the simple display. Biggest dislike so far: This has been talked about...

    SDS100/SDS200: Official Performance Report Google Doc

    SVRCS system Found that my new SDS100 works extremely well with the SVRCS 700MHz system (West site) in south SF bay area, much better than my 436HP, and worlds above my TRX-1. Did some subjective field testing with SDS100 and 436HP in my car, both laying in the seat with stock antennas and...

    Scanner update 3/17/17

    I assume this is not a wildcard TG situation. When scanning and the radio instantly switches to the other timeslot, is it the same talkgroup ID as the first or some other talkgroup? Also when holding on a specific TG ID, will it do the same thing and switch to the other timeslot with a different...

    Manually entered UHF freqs read low on TRX-1

    Just tested entering 461.925 as a conventional frequency into scan list 3 on my TRX-1 and had no problem. I used the defaults which enter it as analog. Did you have any specific settings beyond this? How often does it happen?

    TRX-1 DMR trunking color codes

    <rant> I am in NYC with my TRX-1 searching and finding unlisted DMR trunk systems. I then add systems manually (no computer with me) and everything works fine except I can't select CC's for the trunk site's freqs. Apparently they default to "any" (which is good) but then they can't be changed. I...

    TRX-1: Real world P25 simulcast experience?

    I have both 436hp and TRX-1 and listen to the SVRCS (Silicon Valley Regional Comm Sys) which my community is now using. It's a multisite 700MHz P25 Phase 2 simulcast system and I have the bad luck to live in a fringe area close to the boundary between 2 "West" trunk sites that use the same...

    Wildcard behavior TRX-1

    Update- Additionally I found that by going into the browse mode from scanning (by hitting left arrow), then selecting the wildcard TG, and then hitting SEL, you will sit on the wildcard TG and it will then activate on ALL TGs (regardless of what other specific TGs are in the scan list for that...

    Wildcard behavior TRX-1

    Don't know if this is common knowledge, but thought I would share since I'm a Uniden brat and newbie to GREs. While listening to a DMR system with a wildcard TG, I noticed that while scanning the wildcard would activate on all TGs which were not specifically programmed elsewhere. This is great...

    New California Air to Air Tactical (FM) Frequency Assignments

    More confirmation I can confirm Air Tac 43 (167.700) was assigned and used (and identified as such) on the Nancy fire in the Shasta-Trinity NF in July 2013, along with the new A/G-1 (167.600). Nothing heard on the old A/G 170.000 or any of the (old?) NF Air Tac 1, 2, 3, or 5 channels. Also...

    Found frequencies not listed.

    Thanks for the info. You are exactly right, sounds like an analog audio source for the repeated mobiles that is patched from the audio out of a digital receiver, and it is muddy but readable. No worse than listening to audio directly on a digital scanner from a digital transmission. The...

    Found frequencies not listed.

    Whose PD is this? I am hearing some LE agency on 155.565 with a DPL of 331 from Tuolumne Co. This is an analog repeater where the unit's voice quality is definitely digital (but not the dispatcher's). My location is high on a ridge overlooking a lot of area, I can easily pick up stations from...

    Stanislaus county/Modesto Fire

    New Stanislaus Co Fire Freq? I have been hearing some fire traffic on 154.400 with a PL of 123.0 from Tuolumne County. Not enough for a positive ID, but they did mention "Queen Elizabeth Court" at one point. I know there is still some unidentified Command and Tac channels for Stan Co Fire...

    Disneyland Freqs, Anahiem Help ?

    I have been back and forth to So Cal about 15 times in the past year, most recently 3 weeks ago. I have been using the following freqs as "CC Only" in my 246T the whole time with no problems (these match RR database): 938.4125 MHz 938.4500 MHz 938.4750 MHz 938.4875 MHz Jim

    Ultimate Disneyland Scanner Profile?

    I was just down there a month ago and noticed the same thing on my 246T - Base/Dispatch clear and a humming noise on all mobile transmissions. I wonder if they hear this humming on their system radios? Jim

    BC246T Close Call Autostore behavior

    I have just upgraded to the new (v2.05.01) firmware and really like the new features, but was wondering if the CC Autostore algorithm had changed or am I just crazy. It seems to me before the upgrade that it would detect duplicates (and not store) based on the channels in the Close Call system...
