Title: URRG Member Tracker Frequency List
Post by: admin on March 07, 2016, 12:38:51 PM
Use this topic to see what tracker channel and frequencies URRG members are using at the field. This should help people choose a frequency that is not already in use or know if they need to communicate with a fellow flier who is using the same frequency. Please reply to this post in the following format and an admin will put the info into the first post.

do you mind if we put your name in here so someone knows who to look for at the field?

OK, So I use a tracking system from Communication Specialist, (www.com-spec.com) and I have the PR100A receiver, which can handle 100 Pre-programed transmitters. The R300A receiver can handle 300 transmitters, again pre-programed, you can not change the frequencies on these transmitters.
Here are the transmitters I use for now:
Channel 00 = 223.110 MHz
Channel 73 = 222.510 MHz

So for what it is worth the R300A also uses these frequencies but they correspond to different channels on it's selector as such:
Ch 00 = Ch 311 on the R300A
Ch 73 = Ch 251 on the R300A

One should note that as I have used these transmitters I have lost some due to them not being secured properly within the rocket, (and the coin battery failed before I could locate it) Or they were destroyed during a crash, (usually in someone else's rocket I had loaned it out to, I don't loan them out any more. ). :-(

As a legal note, Torrey Farm is north of Line A, and consequently radio transmission in the 420 MHz to 430 MHz portion of the 70 cm band is prohibited by international treaty.  No trackers operating between 420 MHz to 430 MHz are permitted.

Reference:  http://www.ecfr.gov/cgi-bin/retrieveECFR?gp=&SID=7670851f02e0443ed40e031d3bef21b2&mc=true&r=SECTION&n=se47.5.97_1303

49 CFR 97.303   Frequency sharing requirements.

(m) In the 70 cm band:

(1) No amateur station shall transmit from north of Line A in the 420-430 MHz segment. See 97.3(a) for the definition of Line A.

(2) Amateur stations transmitting in the 420-430 MHz segment must not cause harmful interference to, and must accept interference from, stations authorized by the FCC in the land mobile service within 80.5 km of Buffalo, Cleveland, and Detroit. See 2.106, footnote US230 for specific frequencies and coordinates.

(3) Amateur stations transmitting in the 420-430 MHz segment or the 440-450 MHz segment must not cause harmful interference to, and must accept interference from, stations authorized by other nations in the fixed and mobile except aeronautical mobile services.

Thanks Bob, also, anyone using 70cm or 2m Ham frequencies needs to have their Technician license. It's an easy test and the local HAM radio club offers free tests. Study for the test at www.hamstudy.org (http://www.hamstudy.org) and then take the test at www.siarc.us (http://www.siarc.us). You can also take the test at RIT www.rochesterham.org (http://www.rochesterham.org) or find a local exam at http://www.arrl.org/find-an-amateur-radio-license-exam-session (http://www.arrl.org/find-an-amateur-radio-license-exam-session)

Our local ham club offers the ham test on the 4th Saturday of each month.  I've been planning to take it for the last 50 years so I finally bit the bullet and took it today.  The Technician test is Element 2, the general test is Element 3 and the Extra test is element 4.  Elements 2 and 3 are each 35 questions and you can get no more than 9 wrong,  Element 4 has 50 questions and you can get no more than 13 wrong.  I took the first 2 tests and passed both so they handed me the third test, but it was hot and I had a barbeque go to and I wasn't certain if I could pass it without studying and I didn't want to keep the 10 examiners hanging around for another 40 minutes so I passed the test back.   I'm happy with a general license for now.

Congrats Bob! I was just thinking today I should go take the general test. I wish I had taken it when I did my technician. Now I guess I should study for Extra and see if I can get both.

By the Way--

Tech Ham license is a fairly easy exam. Thankfully, no longer requires any morse code!! 

If you did "OK" at High School Physics, it should not be a problem.  Like the  L2 cert exams, there are a limited number of questions in various categories and there are online (Free) practice exam practice sites.
