• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    XTS5000/2500 tuning/alignment

    I have an XTS5000 and an XTS2500. I noticed that the XTS5000 gets a garbled voice and sometimes the transmissions get clipped. The XTS2500 seems to work fine. This leads me to believe that the 5000 needs a tuning. I'm new to the tuning/alignment world. I have a buddy, that has helped me a great...

    Reference signal to tune my SDR Dongle

    I have the NooElec NESDR Mini 2. I'm just getting started with it and I am using SDR# on a Windows 7 laptop. I know that there is some drift from unit to unit that needs to be compensated for to get exactly on frequency. I am looking for a nice sharp reference signal that I can as a standard...

    DV-1 tuning knob?

    This may sound like the question of an obsessive, but here goes anyway. I've owned both the 5000 and the 5001, and the tuning knob on both was poor. There seemed to be quite a lot of 'play' in the spindle bearing, especially on the 5001. That and the bargain basement plastic tuning knob on the...

    I have a Sinclair Mobile Duplexer in a portable repeater. ( Sinclair Technologies Online Product Catalog - MR254B-2 ) I believe that this is a Band-Pass only duplexer so my question is if I wanted to reverse the TX and RX frequencies do I need to retune the duplexer? Or can I simply swap the...

    Tuning a duplexer (RLB / Coupler vs. Loss)

    Hi guys, I don't know any tech guy in my area who can clear some things for me and I thought I might ask you about something that's confusing me while doing some duplexer tuning. I'm a "young player" and I can fall into a lot of traps while trying to learn. Please forgive my mistakes if I say...

    I have a question about Caltrans tuning for San Diego County. The RR trunking list for Caltrans is very large. Do I have to enter multiple tower control freq's and group Caltrans in separate lists or can I enter all the necessary towers in one TSYS? Does anyone know what the right towers are? I...

    TK-250 squelch adjustment - tuning mode

    I have a couple of TK-250 handhelds that seem to show the 'busy' icon consistently - I'd like to adjust the baseline squelch just a little to make them less sensitive. In the KPG-23D software, there is a "test mode" which gives you an F10 "tuning mode" option. You can then adjust a slider that...
