Scanners

The technical side of broadcasting. Think IBOC is a sham? Talk about it here! How about HDTV? Post DX reports here as well.

What ??
ALL my scanners have a search function where you only have to enter the lower and upper freq limits (takes u forever to search DC to daylight freqs, take one MHz bites to search), Some scanners will enter a freq that is busy into the next available empty channel in the radio, when you search !. Please read the manual thorolughly !

This one has that function too. Whoever made that complaint in their review hadn't read the user manual. Now I have to figure out how to set the range within which I want to search?

Does the radio automatically switch to the mode being used? e.g. AM, FM SSB etc? This stuff is going to take a while to learn.

All my scanners have mode locked to range of freq, AM for Aero band and FM for all others.
You only find CW/SSB is on 6, 2 and 3/4 Meter ham bands . BUT on most scanner type radios,you can not go to the SSB mode.
The really good Receivers that cover HF and up to VHF/UHF, With any mode selectable, are very costlty to buy, around $ 1K and up !
Have fun learning your Uniden Handheld Receiver :D

So, it arrived earlier this week. I still have a lot to learn yet. I haven't loaded anything into the banks yet. Just using search mode. Mostly hams. I expect there will be more activity on the air back at home. I live near a rail yard and also an airport.

Is that black metal framework an antenna project in progress for your new scannder ? :D

That's the patio table. The radio doesn't work as well when it's on there.

Connected to an outdoor antenna tonight. Works a lot better. These mobile homes are like working inside a tin can.

What kind antenna have U got up there ?
FOR my Scanners, I have three magmount whips on the metal roof of my sun room in the warmer WX, VHF Hi, Loaded VHF lo for around 35 MHz and a 5 DB gain UHF ant. Also have a couple of Discones with feedline running down to the radio room,

I was using the dipole I erected here for SWL. I don't have enough real estate here for a proper SWL antenna. Each leg is only 20 ft long. But it seems to hit a sweet spot with my Grundig Sat 750. It works great for SW, MW and even FM.

I tried replicating the same setup for my radio at home and it didn't work worth a damn.

It's far from an ideal scanner antenna, but at least, it's outdoors and up in the air.

I believe this radio has the "Close Call" feature, so if you're lucky enough a nearby unit is in service it will stop and telling you what it found. Getting it back out of 'close call' is a giant PITA, but neat feature. Some railroads are going to NXDN mode, don't know, but SOME Uniden radio you can upgrade to include NXDN or DMR reception for non-analog and non-P25 digital Phase 1 or Phase 2.

Hey, got any secrets for building a 40m band antenna that will fit into an attic without starting a fire from high voltage?

Unless you're trying to run a KW or two, you're not going to start any fires. String out 66 feet of wire in the attic, 33' each side of a center insulator hung as high as your ladder can reach, 50 or 75 ohm coax. Use a choke balun to keep RF off the shield. Run the wire in the rafters, zig-zag it, put it wherever it can go. I have multiple attic dipoles, 100W max, out, typically 40-50W on digital modes and work the world. Anything you put up will receive and radiate RF, just not nearly as well as a full size antenna at optimal height over ground. You do the best you can with what you have. Don' t overthink it.

I run two SDR dongles in tandem with unitrunker and DSD+ for ultra cheap, reliable P25 phase 1 and 2 decoding. You can even monitor multiple control channels (systems) at once and give priority to talkgroups from a global (multi-system) standpoint.

Use a 4:1 coax to wire balun okay for 40m? 4 conductor bell phone wire x 33' each side? Thanks, didn't think to zig-zag it with the ends flapping around.

dipole wire should be insulated if you are worried about fire or detuning by touching odds and ends in the attic. bending ends around a corner is OK but just not bending back against the rest of the wire.
Best advice ...Move to where you can run your antennas up high in trees !

The screen reads "press any key".
I have searched the keys for one that says "ANY' on it. can not find it anywhere ! :eek
