Air ~ What's your frequency? Mystery Cache

This cache has been archived.

ROTSIP: As there's been no cache to find for months, I'm archiving it to keep it from continually showing up in search lists, and to prevent it from blocking other cache placements. If you wish to repair/replace the cache sometime in the future, just contact us (by email), and assuming it meets the guidelines, we'll be happy to unarchive it.

Geocache Description:

Recently someone told me that geocaching cannot be called a sport! Just to make myself feel better I designed this cache which will have you running up and down the length of the Blaauwberg beach... Hahaha... You will still get to use your GPS at the end though - but not before you have had a good workout! ;)


Ok so to be fair I will tell you a few things - You will need a portable device capable of receiving signals in the FM range (like an iPod), then you want to be in a certain place along the footpath between the parking lot at On the Rocks restaurant and ...mmm... a good place to celebrate after having logged your find. (see waypoints)... It's only ~ 1.5km!

So as not contravene ICASA regulations and cast the geocaching community into disrepute, this cache makes use of an ultra-low power FM transmitter - but more importantly low power means you will have to be very near the device to learn the location of the final cache! To make things even trickier you will have to do the same calculations that I did before building this cache...

The transmitter and solid state circuit that produces the signal for broadcast together draw a constant current of 5mA (milliamps) at 1.5V. Powering the system is a set of two 1.5V alkaline 2900mAh (milliamp hour) batteries wired in parallel (still 1.5V). According to the above, after how many days (rounded to the nearest day) will the batteries need to be replaced?

Let the number of days be represented by AB.

So now you can go find the cache - The frequency you want to listen on is [ (AB X 2) - B - 0.3 ] MHz

I will give you an additional hint: Walk nearby every street light along the way!

Sorry - As usual with my caches - The final is super vulnerable! Make sure there are no muggles nearby! I would recommend finding the final in pairs... One body to block the cache from view while the other retrieves!

*** Thanks to Hardusboer helping with this cache... wouldn't have been possible without some peer pressure!

Apparently you might be able to find this one by car! ;)
