<div class="moz-cite-prefix">If you can run your own local IGate on
an alternate frequency, there's a new MT-400 from VHS Products.

<pre wrap="">I have just placed a photo in the photo section of the group of the new MT-400. This is the first completed prototype, and we expect to have them in stock about the end of May. This replaces the single channel MT-300.The MT-400 ( so named because of its 400 mW+ output) is frequency agile, and offers a connector to mate with the Byonics GPS-4, high altitude OEM GPS(PCB level product; no magnet or plastic case) which will switch the GPS on prior to a scheduled transmission, and massively increase the run time on any given power supply. The board has mounting pads for a DB-9, which will be included, but not mounted, since many of you will not want the weight or bulk of the DB-9. It is set up to allow programming through the DB-9 connector ( or the through-holes mounted next to the pads) and like most TT3 style devices, the DB-9 is wired with the TR and RX pins swapped, and +5 power out of the DB-9, so its plug and play compatible with the GPS-2 and GPS-4 ( And mos
t other serial GPS receivers for that matter) This meas you will still need a null modem/gender changer cable for programming. Power through the DB-9 connector is not switched. The board measures 3.910 long by 1 inch wide.Even with all the improvements over the old MT-300, we expect the price to be comparable. The MT-400 will be able to run any of the software Byon writes for the PIC 16F1827, so you will be able to downlaod a WxTrak, FOX, and TinyPack version when/if they are available and reload the software to different versions as often as you wish.

My first APRS device was an MT-300 which was a complete mistake
for terrestrial use on the national frequency, but I could see
such a tracker being very applicable on a dedicated frequency for
quad copter tracking. You could even have multiple trackers on
different copters sharing a local frequency w/local IGate support,
possibly even a cross-frequency digipeater? The key to low power
is local line-of-sight between transmitter and receiver and a
non-busy channel to remove contention.<br>

<pre wrap="">Hello
Getting into quad copters
What is small and suitable ?
Maybe some HAB gear ?
