Great work!

I was made aware of an issue with MIX 94.5 and Triple M 92.9 RDS this afternoon. I suspect they are running from backup Bickley transmitter.
I did major update on my FM antenna setup. Removing the old 8el FM horz antenna pointed east and the 3el FM horz antenna pointed north. An replaced with a 3el vert pol pointed North 9mt AGL and a 3el vert pointed east at 7mt AGL
I see a noticeable improvement on the north antenna. I am still not 100% convinced the east antenna performance

The RDS issue reported earlier have been resolved all back to normal
I forgot to mention that I also removed the 2 TV masthead amplifiers that were being used and replaced the coax with RG6U quad shield approx 10mt in length. This has produced a reduction in the noise floor. I enclosed the top section of cabling in corrugated electrical conduit to protect the cables from the local bird life.
The existing telomast was extended to its full height of 6mt giving me in effect a height of 9mt AGL
With the antennas swapped from Horz to Vert Pol this gives me better reception on the regional commercial services at the expense of ABC/SBS who mostly use Horz Pol. Both antennas were mounted on 500mm Horz extension arms to reduced any effect of the main mast on their performance.

This may seem like a dumb question, but how do you get 2 FM Webservers running on one PC to actually update on the FNM DX Webserver map?
I have two instance of FM web server running two receivers one using 8080 port and the other one using port 8081. I have opened up both port forwarding to the outside world. I can see both web servers running if I access then via my iISPs IP address, but only one FM Webserver shows up on the FMDX map usually the last one I’ve started.
I have waited a couple off hours to see if the maps update, but nothing changes.

To my knowledge, each webserver has a unique OMID (the ID that gets assigned to your webserver). Each time a new one is spun up, the staff on the FMLIST.org website have to generate one for you, except if you manually specify an existing OMID in the FM DX webserver settings. It is apparently best to create an FMLIST account where possible, which I have done but awaiting for the staff to activate.
If you want to see if the logs are ending up on FMLIST, use the ‘Stations from’ filter set to Australia.

Try deleting the token information in config.json. Probably at the moment, they’re both trying to register using the same token so whichever one is most recently opened is the one that shows up:
It’s possible to have all web servers log to the same OMID if you want (as mine do). I just use the antenna name in the comment field to understand which one it came from:

Ideally both of them are at the same location. In my case my two webservers will be ~20km apart so maybe a separate OMID will be better?

Ah, yep. You probably should have a separate ID for each in that case, since FMList calculates the bearings, distances, etc. from the location you’ve selected. For me, all my servers are in the same location, so it’s not an issue.

The issue I am having is when I created another FMLIS account I was refused as I already have a valid account with them. I need to explain the situation to them. Given there are people running multiple webservers I don’t think the OMIDi s the main problem or how did they get around it .

I’ve optimised my AM TEF server with some plugins:
- AM Station Info: Which adds SW station information, including AF information (this has broken my local AM station information though)
- Enhanced Tuning: Which allows you to quickly jump between SW bands
As the AM TEF is not a headless one, I’ve also set it to use the radio’s built-in seeking, so seeking on AM is fast.
It feels like these Chinese SW stations are crazily powerful. The station above is peaks at 100 dBf+ on my TEF and sounds like a local station. Meanwhile ABC Sydney is only about 85 dBf. Though that might be because the MLA30+ is more optimised for SW.

Further to my last post, I’ve created an Australian MW database which might be of interest to other Australian TEF server operators (@ninkeon58). It’ll automatically choose the most likely TX based on your server’s location and TX power. It also has a clickable list of AFs. Here’s an example with ABC Local Radio NSW:
If it hasn’t identified the right station, there’s a button in the bottom right that lets you view the second most likely match.
If anyone wants my database file, just let me know! (PM me)You can also click on the info box for a map:

Sorry if you were on the Bribie Webserver and it jumped back to 1008 after you selected an FM channel this afternoon, I was in the middle of diagnosing an issue with 1008 caused by the storm.

As suggested earlier removal of the token from config.json on the 2nd FMDX Webserver and a reboot brought up the 2nd test FMDX Webserver on the map. There is no need to have a separate OMID
This Webserver is a test running my now spare lower elevated 3el FM antenna on a rotator currently pointed south of me. Nothing much new to hear ATM except reception from lower south west areas like Bunbury and surrounds as conditions improve.
Thanks everyone for the assistance

Out of curiosity, what’s the rotator / how much did it cost?
An old Emtron prob 20yo I got from an amateur operator it is overkill for my small setup to large and clunky to put on a high mast.
I can’t find any quality light rotators under $800
I did purchase a light duty TV Antenna rotators from Radio Parts in Melbourne. It lasted 3 months before it failed. due to the plastic cogs cracking

Thanks for that.
Yikes. At that rate, it’s cheaper to just get multiple antennas and point them in the different directions.
Speaking of multiple antennas, the west antenna on my server is back up and running, though not pointing in quite the right direction (it’ll be fixed up next week).

I have migrated my Radio 1 webserver off to a passively cooled micro USFF PC running Linux, due to the end of life of Windows 10 without resorting to dubious methods. If anyone finds an issue that wasn’t there before, please let me know via DM.
In the next few months, I am planning on setting up my Radio 2 headless TEF out of town, with hopefully a pair of 3 element yagi aerials facing opposite directions and polarisations to my first one. Now I don’t expect it to perform miracles nor receive much if anything different on FM, but on MW/SW thanks to the very low noise floor at night it may be one of the best in class.
If you’re crafty with electronics and some basic fabrication, I’d try and fabricate something with an Arduino and some old gears from a remote control car differential plus some hall effect sensors. Could possibly save you some coin in the long run if you’re willing to experiment

There’s a new TEF webserver online in Qld.
Located at: Eagle Farm, Brisbane, Qld
