Onderwerp: [ukmicrowaves] 24 volt relay on 12 volt

 

Hi All,


Sorry for the newbie question.


As a club project we are having a go at a couple of 5.8g ATV transceivers. I have a suitable SMA relay, but of course it's 24 v. I know I've seen links fairly frequently to circuits to produce the kick from 12v, but I cannot find any now.


Please could someone pass on a link.


The relay I have pulls in at 15v and drops out at about 5 v BTW.


Thanks


Nick G0HIK

ADF5355 Phse Noise

Andy G4JNT
 

I've made some plots of the phase noise of an Ebay-Special ADF5355 Synth generating at 10GHz  (well, actually the VCO runs at 5GHz and is followed by an on-board doubler, but whatevs)

You'll find the plots at http://www.g4jnt.com/ADF5355_PhaseNoise10GHz.pdf   The plots are in a 6Hz noise bandwidth, so dBc/Hz will be about 8dB below the curve.

The reference is a good quallity 10MHz TCXO and the reference doubler is enabled for a 20MHz Fcomp

About -65dBc at 10kHz spacing - it could be worse.

Increasing the charge pump current from the 0.9mA that is the default value when using the Analog devices design software to generate the register settings up to 3mA seems to show a few dB improvement in close-in PN ands sllightly flattens the 'humps'

The GM3WOJ personal 10 GHz beacon is back on after an absence of a couple of months due to a power supply fault. It is on 10368.400 MHz. Further details are at:

Re: ADRET SYTHESIZER 5104

Hi David
 
That’s good to know. I have two Adrets which I have managed to keep working for many years. Having two means that I can swap the plug in units and at least isolate which is the faulty one. Having the proper extenders would make things much easier! I have a copy of the training manual which is essential.

If anyone is using an Adret Synthesizer 5104 (90-120 MHz) as a local oscillator drive source

please note that I have a set of extender cards so that each module may be moved out of the

casing to fault find etc.  I also have the training manual and sevice manual.

Hi,
Does anyone have a rotator they no longer use/need?  I have at long last got a pump up mast I can use when I go out portable but need a rotator as it can't be turned by hand. Anything considered. It needn't be very big as I only intend to use it for my 23 and 13cm antennae.

Many thanks

I'll be QRV 24GHz but everyone's too far West again :-(

The UKuG 76 GHz loan equipment is gathering dust in my garage for the same reason, no takers either to use it, or in range to test with! 

Hopefully G3XDY will be up and running on 24GHz from home and we can try or we get some decent rain to the West of here.

Talkback: Phone 01223 862480. KST, Twitter and WhatsApp

Times: In and out of the shack throughout the day and on the end of a phone.

Reports and beacon spot.eu spots on GB3CAM 24048.870 (GPS locked) IO92WI53 200mW to omni @30m agl CW and JT4G  would be much appreciated.
