Water lock in floor drain

How to open and clean a water lock in a floor drain looking like this (see photo)

In a house in Denmark I needed to clean the water trap in a floor drain looking like the one in the photo. (For some weird reason, these kind of household tasks always end up on the male… But that is another discussion :).)

Water lock in a floor drain in Denmark

I wrongly made the assumption that I needed to unscrew the four screws. Bad decision! This made the upper and lower part of the water lock to separate and the lower part fell into to the waste water pipe. Fortunately there was a bend some 30 centimeters down so it stuck there and I only (!) hade to put my arm into the pipe, grab it and pull it out.

To get the water trap out was actually more simple than anticipated. This how it should have been done: just put your gloves on, stick two fingers in the big hole and a thumb at the edge and pull. When removed and safely away from the waste water pipe, the four screws can be unscrewed in order to separate the two parts of the water lock so it can be cleaned more easily.

Anytone AT-D578UV stealth installation in Toyota Prius (2008)

I wanted to make a “stealth installation” of my Anytone AT-D578UV radio in my Toyota Prius (2008) so I don’t have to worry so much for burglars when parking the car. Below the FM-radio is a compartment, when removed, leaves a space big enough for the radio.

There is plenty of space behind the compartment. I was a bit worried about that issue becase the radio is longer than the depth of the compartment, but it turned out there is enough empty space behind it.

I installed the radio with the programming cable connected as it will be very hard to connect it after the radio is mounted in the car. The microphone is extended and connected using a flat straight ethernet cable and both cables are dropped downwards and pulled out from behind the panel. That way I can easily hide the microphone when parking the car.

When the compartment under the radio is removed (and saved to be reinstalled when selling the car), the space between the metal plates is to wide, so I took a 5 mm nylon cutting bord that I cut into pieces and glued them together to form a suitable spacer and drilled a hole for the mounting screw. I did not use the mounting screws that came with the radio, instead I used one M4x20 mm and one M4x40 mm. On the right side of the radio I used 2 nylon pieces and on the left side 5 or 6. The screws went into the rear holes on the radio and to get some support for the front I used zip tie straps around the radio through the holes in the metal plates.

The GPS was just tucked up behind the navitor screen, just to the right of the speaker.

For power, I routed two 6 mm2 wires directly from the battery (with a 30A fuse close to the battery) and routed them through the left trunk panel and inside the side panels below the doors to the front. The antenna cable went the same way and I didn’t want to drill a hole in the car so I used a trunk lid mount even though the performance for those are often not as good.

These are some useful tutorial videos as you need to uninstall and reinstall the stereo in order to install the Anytone AT-D578UV below it.

Anytone Talker Alias

How to enable Talker Alias on Anytone AT-D878UV / AT-D578UV

With the number of assigned DMR ID:s on radioid.net going over 200.000 we are over the limit of the capacity for the Contact List on the older Anytone models. Anytone:s under estimation in design is not the first in history. Remember Bill Gates saying that no-one, ever, is going to need more than 640 kB RAM?

So we need to select which regions of DMR ID:s to incluide in our contact lists in our Anytone radios.

In addition to that it is a good idea to enable Talker Alias to sort of increase the chance of just not seeing a DMR ID in the display. Not all repeaters supports it though.

  1. Make sure your own Radio ID Name is set in the form “CALLSIGN Name” (your callsign and first name separated with a space). Set your radio on a DMR channel, then MENU -> Settings -> Chan Set -> Radio ID -> select your ID -> Option -> Edit Name -> Confirm
  2. MENU -> Talk Group -> Talker Alias -> Alias Tx Set -> On
  3. MENU -> Talk Group -> Talker Alias -> Alias Rx Dis -> Contact First
