It is yes but the handheld scanners won't allow the last 5 on either so set st 148.637 and 148.562jkl090 wrote:And isnt the freq supposed to be 148.6375?
unsure where it comes from... maybe the university hospital ? I am located in labradorjkl090 wrote:are they both transmitted from the same place?
This is the 2 frequencies i use... both frequencies are at hospital and sports centre.. 1 site is no more than 2kms away north and the other is 4km south.... and other pic is the aerial i bought and new 15m cable... to splitter from daveVK3RX wrote:Handheld scanners usually don't do well with outside antennas. Their sensitivity is matched to the short flexible types supplied, so outside antennas can cause overload and intermodulation from strong nearby transmitters.
So something could be causing you interference or reduced sensitivity on 148.6375MHz.
As to where the transmitters are located, try this:
- go here: https://web.acma.gov.au/rrl/assignment_range.search
- enter your location e.g. Labrador in the "From location/site" field and pick any site that comes up in the area;
- enter a radius e.g. 15km;
- enter a low and high frequency range e.g. 148.000 MHz to 150.000 MHz (don't overlook toggling the field to "MHz");
- ignore the authorisation dates, and hit "Submit".
I have no idea about any of this. I spoke to a radio communications company explaining what i have and need to achieve and this is the antenna i was told to get. Any recommendations on antenna or a way to fix this issue?VK3RX wrote:Hmm ...
Those two frequencies are very close together, transmitters only 2-3km away from you, each radiating 500 Watts EIRP and you are using a 3db gain antenna, and quite a few other pagers within 10km - it's not surprising you are having a problem. I also note that the same frequencies are used by the same provider at two different sites in proximity, so there may be some interaction at your end with the two sites.
If it has the facility, you could try turning attenuation on in the scanner having the problem. Alternatively connect the flexible antenna that came with it and see what the results are.

You could try this ready-made 20dB variable attenuator. About $20 on ebay.
It would go between the antenna cable and the input to the splitter.

All done and no difference that i can see... put between antenna on roof and input on splitter right. 148.6375 rarely seems to get alpha just bs as per pic... attenuator is set halfway atmScannersplitterguy wrote:Even better, if you can get one locally.
Just remember to buy a F-F joiner as shown in the pic I posted above. I can't see it on the Jaycar website.
normally yes.... but tonight i swapped frequencies on the scanners and was getting 92% on .6375 and crap on .5625.... totally bizarre... now same old 100% and clear on .5625 and crap on .6375 as usualScannersplitterguy wrote:What happens if you swap frequencies on each scanner? Does the same problem occur?
On 5625 when 100% it is on earphone 1.... if i move to another one it drops bad.... if i have 2 instances of same saved as 1 and 2 do any setting need to be changed or anything?Scannersplitterguy wrote:I'm out of ideas![]()
Sorry....
After a long night i have seen that soundcard configuration settings mean a lot.. get 100% on .5625 as earphone 1 and discriminator 2. Others arent too good....so have now set. 5625 as earphone 1 and .6375 as discriminator 2... will run today a few hrs then swap them.and will see if i can get .6375 to get any better then its 40%...Scannersplitterguy wrote:I'm out of ideas![]()
