I guess this is strictly off topic but I am planning to be out portable tomorrow (Saturday) from Dunkery Beacon IO81LS for the ATV activity day and will be active on 146 MHz RB-TV, 70cms RB-TV & DATV. 

 

I will also have 10 GHz narrow band to try and work a few people in the RSGB and IARU contests – unfortunately I won’t be around Sunday as we will be setting up for the final ARISS contact in Ottery St Mary on Monday morning.

Subject: [ukmicrowaves] Activity List for UK Microwave Group Low Band Contest Sunday 8th May

 

 

I will assemble the usual activity list for the UKuG Low Band Contest
this coming Sunday 8th May.

It takes place from 08:00 to 14:00 GMT (09:00 to 15:00 BST) on 1.3, 2.3
and 3.4GHz.

This event is coordinated with the IARU/RSGB events over the weekend of
7/8th May, so there should be a reasonable activity level with some
continental stations to work.

If you are taking part in the other events as well then you don't need
to start your serial numbers from 001 for the UKuG event.

Please send your activity plans in the format below, to reach me by
close of play on Friday. I will publish the list on Saturday morning.

Callsign: G3XDY

Locator: JO02OB

Bands: 1.3GHz 400W 4x23ele

2.3GHz 100W 0.8m dish

3.4GHz 20W 0.8m dish

Talkback: Direct CQ on 1.3GHz, ON4KST and 144MHz

Times: Throughout.

I plan to be QRV on 23cms, 3cms and 24GHz over the weekend at various times

Callsign: G4BAO
Locator: JO02cg
Bands: 1.3GHz 350W 44ele
10GHz 7W 0.6m dish
24GHz 1W 0.6m dish

Talkback: Direct CQ on 1.3GHz, ON4KST

I'm particularly looking for JO03, IO93 or IO91 square (or any I haven't worked!) on 24GHz to complete my first 5-square 24GHZ UKuG award.

Anyone planning to go to any of those with 24GHz?

I already have JO01, JO02 IO83 and IO92 but happy for any QSOs on that band

I will be QRV in the IARU 432 and up on Saturday and UKuG Low Band + 432 and up on Sunday. I will not be operating full time. The grass is growing and the veg garden needs tilling!

JO02pa
23cm, 13cm ( both 2320 and 2300 as requested) and 3cm. I will have the portable 24GHz system in the garden.
I might be able to rig an antenna for 9cm and (maybe) on the EME system on 6cm.

Re: Fans

Hi Nick and John
 
Many thanks for the info. I was going to use the cpu fan to cool the copper slab on which a 1 watt 10GHz amplifier is mounted. The tip about the ferrite beads is useful and easy to do as the wires are very thin.

Hi Mike,
 
The white wire is used to count pulses from the fan and used to control it’s speed. Be careful with computer ect DC fans as they use electronic circuitry to control the speed and are vulnerable to high RF fields. I have blown several up due to this. You need to apply ferrite beads as close to where the wires terminate on the fan as possible, and decoupling capacitors are a good idea as well. I generally run them constantly on TX and employ a 50C thermal switch on the heatsink which runs them continually if the heatsink temperature demands it.

Hi All
 
Sorry this is a bit OT.
 
I have a couple of small fans I want to use to cool a heat sink. One is on a small heat sink and looks as if it was intended to cool a CPU, the other is off a defunct DVD recorder. Both have three wires, red, black and white. DC applied to the red and black cause the fan to rotate. The question is, what is the purpose of the white wire?
 
Thanks in anticipation!

Hi Mike

This link gives a bit of info on the various fan wiring arrangements. I think its safe to say you can ignore the white wire, just leave it isolated.

Re: DEM 180 MHz xtal

John E. Beech
 

Thanks Ian,
                   I've e-mailed DEM. I've also had a closer look at their LO frequencies. I actually need a crystal for 179.666 MHz to cover 2300.000 to 2302.000 MHz with 144-146 MHz IF. I'm wondering if the existing xtal ( which I think is 180 MHz) will pull down to this frequency.

           If it will it will make the job a whole lot easier!

Hi All,
         Would anyone here have a 180 MHz xtal suitable for a Down East Microwave transverter? Why, the person who bought the kit forgot to specify the xtal frequency and it came witht he one for the higherpart of the band. ( I did a qick search of DEM & got zilch.) Anyone know the spec so I can order one from somewhere.
