Have located source for the discontinued 706 transistor final -
SRFJ7044...pricing on way.
They say they have 65.
Might others be in need...might be able to get volume discount.

Hi Gents:
I picked up a couple of wide spaced variable capacitors...a heavy duty rotor
inductor...its wired for Pi right now...can alter that as I wish to L...T..or
other.
Hamfest costs maybe about $25 each for the variables...$30 for the variable
inductor...pine board was laying around

Glad to see the replies - thank you.
My intent in submitting the letter is mainly political.
That is, I asked for special consideration for Amplitude Modulation as it
seems to me that AM may get less 'respect' in the future than present.
I believe that FCC rules will allow AM to have the same b

Hello Fellow AMers:
Following is a reply from Zac Lau in the Technical Services group at ARRL to
these questions:
1. How much Frequency Modulation is permitted in Amplitude Modulation
mode?...on bands 160 thru 20.
1a. How is this quantity measured.
2. Is it illegal to modulation the oscilla
Hi All:
As I understand it, low level modulation is anything prior to the amp.
Therefore, is it possible to modulate the grid oscillator RF input signal -
crystal or otherwise - and expect an AM output?
Next question: how?

Hello All:
It is my observation that there is a goodly amount of 'open' space from 14.3 to
14.35 MHz. most of the time.
Conditions are not favorable as 75...but having ample 'elbow room' sure feels
good.
Would it be worthwhile to consider an AM gathering location there?

Thanks for all this education on the plate modulator for my 2 x 813's.
