They are in the 149-152 mhz range.
I have 9 ATS 2440 Glue-on Radio Transmitters for sale (cheap)! I have other much needed equipment to buy for this summer. I purchased these transmitters last month and willing to sell them for practically nothing. I bought them for $147 each, but I'm willing to sell them for far less than that. Send me an email if you are interested: Gretchen.Newberry@coyotes.usd.edu (see the ATS web site at https://atstrack.com/ChoooseProduct-4-10-Glue-on---Tape-on-models.aspx for the specs).
