FM-10A & FM-25B comparison

[MaccidX]

Can anyone tell me what is the power output on the FM-10A and the FM-25B???

Also, how much will the LPA1 help them???

[mingkee]

by the report from other users
FM10A has 8mW
FM25B has 25mW (max, adjustable)

if you'd like to use LPA1, your transmitter should be in metal housing to get better shielding, and put ferrite ring on all power in, audio in, and RF out for inductance

what is a ferrite ring and where can I get it??

[mingkee]

Radio Shack.....
looks like a small cylinder around computer cable (near plug)
and LPA1 is said can power up to 1watt, but you're likely to use external antenna with it

[MaccidX]

so, you think I should get the LPA1 for longer range if I use it with and external antenna??

also, I can't find the Ferrite ring on Radioshack.com, can you help me find it, please?? (sorry to bother you, it's just that you are a great help)
