Hi Don,
 
The MFJ discone tends to fall apart in a wind from what I have read. They work well in an attic.

Don;

What do you find is the problem with a MFJ discone, I have been looking at them in their catalog and was thinking of purchasing one?

Stick up the biggest ham 2m/70cm dualband 5/8 on 5/8 co-linear vertical you can.

Re: Antenna Recommendation

Sure, the Austin Spectra is “good”. But, is it over $100 better than the Larsen tri-band, which is only $30? I don’t think so.


Re: Antenna Recommendation

ja moran <analon1@...>
 

I get antennas from Talley Communications great service 
you can get the NMO mounts with a magnetic base 

what I did was maxe an inverted U using 3 pieces of aluminum angle irons 1/8 inch thick.  I screwed one section to the left and righ side of the truck and pan he other section between the uprights.  In or 7the section that is parallel to the truck, I drilled the 3/4 holes amd mounted the NMO antennas....   If you get antennas with a spring or that flex a litle it makes it easier to go through drivethrough or into garages or park under canopies.

I have 6 antennas along the back of the truck.  Different antennas for different wavelengths.  I also have several radios

most of the services I monitor are on 460mhz or 750/850mhz   the 460 mhz antenna works for both

150 300 450 600 750 900  for these he same antenna works well

Re: Antenna Recommendation

Joe M.
 

Your best bet might be a ham antenna that covers 6M/2M/900 MHz. I believe such animals exist (if not, try 6M/2M/440 MHz). Just keep in mind that the more bands an antenna covers, the less efficient it will be on any one of them.

Worst case, use a diplexer and two antennas - one for Low Band and one for the higher frequencies. Just make sure the ports of the diplexer match the bands of the antennas. This actually may be the best performer since the antennas will be more efficient and the diplexer loss should be insignificant.

You’re probably missing Zadig which loads the driver for the dongle. Wherever you downloaded Unitrunker from should have Zadig. Run it first. And every time you reboot run Zadig again.

Hi Charlie,

 

I know there has been quite a number of replies to your post, and I am not sure if the following has been brought up.

 

SDR dongles do 'ok', and may solve your requirement for P25.

 

Unitrunker is a free windows based SDR software that decodes P25 (Phase 1 unencrypted) right out of the box.

 

 

You want to use the latest version, as of this typing I believe it's v2.1.0.9 

 

I have used this software many times.  For basic P25 digital, it works fairly well.

 

Little bit of a learning curve, but if you have any questions feel free to reach out to me.

 

One great thing about this software is that it is always upgraded and new versions come out regularly with bug fixes and new features.

Buy one of these RTL-SDR radio receivers for $25 that is USB:  https://www.rtl-sdr.com/rtl-sdr-quick-start-guide/

Download the free SDRSharp sofware:  https://www.rtl-sdr.com/tag/sdrsharp/

Add this crude scanner plug-in to that software:  http://www.freqmgrsuite.com/

Pipe the audio through the free DSD+ decoding software: https://www.dsdplus.com/

This kludge is finicky and slow, but it's not $600 like a Uniden SDS-100. :-)  It works for my semi-rural area where there are only three P25 public service frequencies and one DMR ham repeater to monitor.  My 246 handles the rest like champ.

Re: Rebanding

Joe M.
 

That's pretty easy. Just program the 866-869 MHz frequencies 15 MHz lower and enter the two trunking tables you can find via Google.

Most databases should now show the new frequencies which will be in the 851-854 MHz range.

Took your advice and attempted to use UniTracker with a RTL 2832u dongle (which is running fine with SDRSharp). UniTracker recognizes the dongle but selecting ‘start’ does not start anything and the dongle remains ‘stopped’. Is UniTracker a stand alone scanning program or must it be used with another program?  New to this but stumped

 

Any help appreciated

Hi Charlie,

 

I know there has been quite a number of replies to your post, and I am not sure if the following has been brought up.

 

SDR dongles do 'ok', and may solve your requirement for P25.

 

Unitrunker is a free windows based SDR software that decodes P25 (Phase 1 unencrypted) right out of the box.

 

 

You want to use the latest version, as of this typing I believe it's v2.1.0.9 

 

I have used this software many times.  For basic P25 digital, it works fairly well.

 

Little bit of a learning curve, but if you have any questions feel free to reach out to me.

 

One great thing about this software is that it is always upgraded and new versions come out regularly with bug fixes and new features.

It is possible for monitor P25 for cheap using your computer.

Buy one of these RTL-SDR radio receivers for $25 that is USB:  https://www.rtl-sdr.com/rtl-sdr-quick-start-guide/

Download the free SDRSharp sofware:  https://www.rtl-sdr.com/tag/sdrsharp/

Add this crude scanner plug-in to that software:  http://www.freqmgrsuite.com/

Pipe the audio through the free DSD+ decoding software: https://www.dsdplus.com/

This kludge is finicky and slow, but it's not $600 like a Uniden SDS-100. :-)  It works for my semi-rural area where there are only three P25 public service frequencies and one DMR ham repeater to monitor.  My 246 handles the rest like champ.

I have used a Larsen TriBand NMO mount for years. A bit pricey but a superb antenna.

Here's an example on eBay. https://www.ebay.com/i/372555516598

Or just Google Larson TriBand mobile antenna

Any suggestions on a mobile antenna for a minivan to use with an SDS100? Just traded the pick up for a Pacifica. Had a high band antenna put on the truck that helped tremendously.

Thanks,
Tim

If you like the truck antenna, why not just put it in the van?
(or the same thing if you traded it with the truck)
