Eggtimer Rocketry is proud to announce the availability of our premier GPS tracking product, the Eggtimer TRS GPS transmitter/altimeter and the Eggfinder LCD receiver on the 70cm Ham band. This is our first Ham-only product, with some advantages over the non-licensed 900 mHz band products...
* You get about twice the range for the same amount of output power vs 900 mHz... with 100 mW of output power you should be good to at least 50,000' (and probably significantly more, since we've hit over 30K with the 900 MHz TRS).
* Compared to higher-power 70cm GPS transmitters, the 100 mW output will give you better battery life and/or allow you to use a smaller battery and still give you good range.
* There are 300 channels available, from 420 MHz to 449.900 MHz in 100 KHz increments, to accommodate just about any local band plan.
* Your call sign is sent out along with the GPS data, for FCC Part 97 compliance.
The 70cm Ham products are $10 more than the 900 MHz version, because they include the external antenna and RP-SMA connectors on both the TRS transmitter and the LCD receiver, which collectively add about 4 dB of gain budget. The 70cm TRS sells for $100, and the matching 70cm LCD receiver sells for $65. If you buy them together, it's $160 (you get a $5 combo discount).
BUT... as an introductory special through October 6th 2019, we're selling the combo for $130... that's actually less than the 900 MHz TRS/LCD combo. If you want an extra 70cm TRS transmitter, it's $80 instead of $100.
To order, send us an email, [email protected] . We will need your FCC-issued Ham call sign, or an international equivalent.
As always, thanks for your support!
