FM transmitter / PA
I have a 7 watt FM PLL exciter that I'd like to drive into a tube amp...
Something between 5 and 50 watts would be ideal. I don't have the workshop facilities at the moment to construct anything so a kit would be a better option.
Can anyone suggest something?
An RF tube amp kit? I'm not aware of any. There are some SS kits/modules available.
Perhaps try looking at some of the older HeathKit 2meter amps,it's not too difficult to 're-tune' it to the 3meter (FM broadcast) band.
Aren't you only (legally) allowed around 300mw in NZ?
Here's a small ~1W amp,built using a 6AK5. It only needs 10-20mw of drive.
well it's going to have to be linear, and ~100MHz... so... 829B.
Good luck finding a kit. haha. ;)
that's Fred ;)
In the past, I have used the PA from an old 160 MHz two-way radio.
I increased the number of turns on the input and output tanks (by nearly 100%) and retuned.
As I recall, I used the PA strip from a Motorola radio and built a new power supply.
It worked well.
