I am a junior who is relatively new to free flight and am in need of a tracker. I would be using this tracker primarily for large rubber models such as F1B and F1G. If anyone could give me pointers on where to get a new or used tracker for less than $200, it would be greatly appreciated.

Hmm,
Jace, I don't know of any new tracker systems for $200.00 other than the home made varieties that I've seen some modelers use from the UK. The two types mainly used in the US are the Walston Retrieval System, and Pim Ruyters (from the Netherlands). LL Electronics also make a nice system (US manufacture). All of those cost more than $200.00 new I'm afraid. You might be able to find a used system if you advertise here and on SEN (Scat Electronic News) and NFFS Digest. Someone would probably sell you there old system.

E-mail me at [email protected] and I might be able to find something suitable for you.

As Tony says, even the cheapest systems are well over $200 new, and his suggestion of buying second hand is a good one. I would just add that if you can't find a complete system, buy a bug or two and then get a decent secondhand handheld scanning receiver. Makes such as the Yupiteru MVT7100 and Yaesu typically go for $100 or less on eBay. Don't go for a really cheap brand as the sensitivity isn't as good. You can also make your own high gain directional antenna from plastic pipe, alu tube & coax cable for a few dollars - there are quite a few designs to be found on some of the internet ham radio sites.

The heading seems to fit so can any one answer this please? On my last outing, I was getting a very poor and erratic signal from a model I could see on flat open ground (Barkston). Is this an effect due to the aerial being in contact with very wet grass?
Also, can anyone give me a definitive recommendation, including model number, for a replacement receiver at least as good as my ancient Standard C156E?

Yes, wet grass almost certainly the problem. It will earth. or certainly partially blank out, the aerial. For real fun try getting a good signal in wet eight foot high maize at Poitou.

I can imagine - and retrieving in that situation must really test ones stamina and devotion to the game!  But what about these latest trackers - with GPS etc. - not far short of it standing up and waving to you and crying "Here I am".  Hmmmm......... seems a game for wimps now!!

A lot of us are now using a Baofeng UV-5RE which can be found on e-bay for less than £20!!!  It was recommended to me by Trevor Grey; it is very good value and I reckon it is as good as my Pym Ruter receiver.

 Pim Ruyters (from the Netherlands).
Tmat

the only tracker I've ever had or used was/is a Pim Ruyters that I bought from FAI Model Supply many, many moons ago. I use a Radio Shack receiver, and it has worked OK for me. I can get within 20-25 feet of the airplane in tall corn, and then I just "shade" the antennae using my body (I hold the receiver against my chest and turn until I can't hear the ping. I then turn the other way until the ping fades. I know then that the airplane is behind me. Not very sophisticated, but it works)

Is the Ruyters still commercially available? If so, where?

Thanks

He was still making them as of September 2017. His email is [email protected] if you want to check current availability.

Jace's original question asked if there was a tracker for under $200.
So we have the Baofeng receiver for £20 or so, and isn't there the Leobodnar transmitter for £50?
So that's less than $200 (despite the mixture of currencies, and the passage of 5 years).

As I slowly learn about this tracking business, I am wary of cheap receivers, having tried two Maycom devices. I recall a retrieval from some very difficult terrain (for those who know Luffenham, the brickworks). We were a long way from the model when I got s signal on my tatty Standard C156, through trees, deep cutting, industrial area and houses, about half a mile away. The Maycom woke up when I was about 50 yards away with line of sight. This might be ok somewhere like Barkston which is a relatively simple landscape, but not where things are more complicated. Anyway, I have luckily just obtained a Ruyter receiver, so we'll see. I'll do a comparison next time we're out.
Thanks for the comments

Have you turned the noise filter (or squelch) "off" with all your radios? If these are "on" and at different sensitivity, it will make huge differences for the range you will pick up the signal.

Under further thought, I'm not 100% sure what I have is a Pim Ruyters beacon. The one I have looks like a "Chicklet" (About .25 X .25 X .125) and uses a small cylindrical fishing lure battery that plugs directly into the beacon. It also has a long, thin, wire antennae.

Sounds like a Ruyter. He offers two styles: a rectangular one, the other a cylinder. They both use the fishing lure battery.
