• 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.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

    Yaesu: New Yaesu FT-3DR

    I need to do some research on Internet connections to the DR-2X repeater and also upgrade the FT2DR with the new node stuff. It would be interesting to be able to connect to the repeater when out of town with the FT2DR or FT3DR in node mode.

    Yaesu: New Yaesu FT-3DR

    It all boils down to how much $$ are you willing to spend. Even with the new Yaesu FT3DRs fairly high price, its cheap compared to main line LMR gear. I buy a lot of hamster radios and for the most part you get a lot of stuff for your money, with varying degrees of performance of course. Maybe...

    Can a Larsen NMO 34 be cut to do 6-meter?

    On the Larson coils, they are just a loading coil and have no taps for impedance matching, so you can trim the whip quite a ways without causing a problem other than its short and inefficient. A/S and a few others did have impedance taps on their coils.

    Can a Larsen NMO 34 be cut to do 6-meter?

    I had an old NMO-40 range antenna and cut it down to 6m. It ended up pretty short and although it tuned up ok it just didn't seem to work very well compared to a full length NMO-50. Its been many years ago but I remember it was only about 2ft tall after tuning.

    Cross band Repeater Question

    It wont work mainly because the FSK modes would have to be received, demodulated then remodulated and transmited with FSK receivers and transmitters. The BW is secondary in this case. If a digital mode were AFSK like the AOR digital modems, then it can be received, demodulated and modulated...

    Grounding

    The National Electrical Code says you must bond the new ground rod to your house main electrical panel ground with no less than 6 ga copper wire. There are length restrictions on that where you may have to upsize the wire. See...

    Yaesu: New Yaesu FT-3DR

    I had a VX7 that was sealed and fairly water tight and when the radio heated up the internal speaker would be pushed outward touching the speaker frame and distort the audio. You had to burp the radio by pulling open a rubber jack to equalize air pressure every once and awhile. Maybe the FT3...

    Atcs antennas question help!!!

    At 900MHz height can be as important as gain. The higher you are the less stuff is in the way of the path between antenna and whatever you want to receive. At roof level you might have 100 houses or buildings in the way of what you want to receive. Put the antenna up 50ft and you cut a bunch of...

    Cross band Repeater Question

    Never mind, my brain was thinking AFSK when FSK was posted.

    Cross band Repeater Question

    Are you saying DSTAR can be cross banded through something like a Yaesu FT-8900?

    Yaesu: New Yaesu FT-3DR

    The VX-8 series uses a threaded 1/8" plug, which is fairly sturdy but doesn't come in a right angle version. I have an aftermarket speaker/mic on my FT2D and so far its ok with its right angle plug. It swivels when it needs to and it hasn't popped out yet.

    Best Wideband Antenna for SDRPlay

    The AOR works ok for its size, there is a 6ft whip with a very high ratio transformer to match the many thousand ohm impedance of the short HF whip to 50 ohms, then it feeds the low frequency side of a diplexer. The UHF/VHF side is a resonant whip with various loading coils that feeds the high...

    VHF Anomaly !

    When I go hiking at a local park on a hill in coastal Los Angeles with a 1W APRS beacon and 1/4 wave whip, I usually get picked up by a station in Mexico about 170mi away. Seems APRS beacons will decode well below levels where voice would be usable.

    VHF Anomaly !

    The guy I referred to in my last post built the 10GHz beacon for Hawaii. Chip Angle N6CA, used to own Angle Linear. I seem to remember its been heard but I don't believe there has been a two way 10GHz contact yet.

    VHF Anomaly !

    A friend of mine has talked from Kalifornia to Hawaii on 900MHz, 1296MHz, 2.3GHz, 3.4GHz and 5.7GHz via tropospheric ducting. These were two way contacts. A Kalifornia 2m repeater on Catalina Island occasionally gets some people from Hawaii checking in. Poland to the US east coast is believable.

    Single antenna setup for both transceiver and scanner

    The one I got is an Advanced Control Components model ACLM-4896C46. The Ebay seller had a couple of them but it looks like he sold out. I should have bought several. I think this one handles about 10W continuous as is and for 60W continuous you bolt it to a heatsink.

    Single antenna setup for both transceiver and scanner

    I would install two separate antennas and use an RF limiter on the antenna feeding the scanner. Here is a cheap limiter that will handle up to 2 watts in from a nearby antenna, then clamp it to a lower level that should not hurt a scanner. RF coaxial limiter 1MHZ-1000 MHz 10dBm F/ VHF amplifier...

    ICOM R-8600 or not - That is the question!

    Here is the 100KHz test again under the same conditions I reported some time ago when transmitting at 50W which vagrant asked about. Two friends are conversing on 146.520MHz and I transmitted at 50 watts or approximately 200W EIRP on 146.620MHz only 40ft away from the Discone feeding the Icom...
