PCS-Electronics

Say something,
Here's my resume
I attended pcs university, no need for mit
From March 2 2014 march 11 2014
Graduated today
Courses: read the entire antenna forum, did not miss any.
Talk to me now.

I will like to collaborate on building this antenna

2 transistor on an amp module , each one will need to be bias separate?

I have a few more questions,
How do you disable the pallet to perform this test?
Where on the pallet do you measure from?
Is it that the positive probe is placed on the +5 and the negative on the ground
Meter in milli amp mode?
Is that correct?

Hi,
Where do you measure the bias voltage or current from ?
Is it the voltage that's important?
Or is it the current?

Hi ,
Are there Any SWR Protection circuits or board available that will kill power or shutdown the transmitter in case of high SWR .

this is very useful in cases where the antenna be comes detuned from excessive sun/rain/ice or coax being tampered with

lets talk a bit about this cavity filter
how does it work ?
what does it do?
how do you select one for your frequency?

Technical specifications for PCS/1001, double cavity:
- Form factor: Assembly, see photo
- Connectors: N
- B.W. (-3db): 800 khz - 1.5 Mhz
- Insertion Loss: <0,4 dB
- Power handling ...

can using better grounding technique help in making the signal travel and penetrate better?

system Can a good grounding system cure static from getting into the fm signal?

Do you have enclosures for your low pass filters?

i found it , i calculate the system power .
here`s what i found , i will need 160 watts of solar panels to run my system.
i only have an average of 9 hours of sunlight.hope this is enough to charge and run the system.

i have a question on powering the Max Pro 4025 from solar system .
the system require a Power Supply of 11-15V/5A per hour multiply by 24hrs each day.
so i can say it will need 120 Amps per day.
how do you calculate the required solar panel to charge the battery system and run the maxpro4025?
what ...

I would like to increase the output power of my 25 watt transmitter. In order to increase the internal amplifier wattage wouldn't i just install an attenuator with the bigger amp and keep the RF power below the max range of the attenuator?

Although new to radio i can build computers so i am ...

are there any math formula to calculate this?

so now we have a math question for all the math guys here on this forum.

i will like to dive the SD2941 Amp with one watt.
the pallet will do 175watts with 4 to 5 watts drive at 48 volts/7 Amps i also have a gain of 16db

again i will drive this unit with one watt with a 15 volt power supply @ 12 ...

can you explain these two boards?
i don see much on either on you site.

Is the Max pro 4025 + Shipping?

what is the required module for the control?
what version of the max pro 3000+ ?

i see you now have the USB IO Board +
and the RS232 IO Board
what is the difference between the both?
do you have the same controls on both?

This is more than enough, the drive power you need
typically is just 2-5W, stereo encoder uses practically
nothing and fans are also using just a couple watts.
You can also connect fans to 24V or 48V directly (these
types exist) or even 110-240V.

I don't see any need for more, really.

I usually use 1-2dB.

It really helps things.

do you make or sell a RF attenuator that will pass 10 to 12 watts on the output, the drive required is 12 watts.
