Thanks Mark, copying this to the group for info. Hope you can fix your posting issue. I guess it would be simpler to glue single-sided ceramic board down than using double-sided pcb and

Hi Mike Thanks for the information. I was just checking on Thursday when it wassupposed to be off for maintenance, but I was still seeing the signal indicatoron a clock .Perhaps they changed their

Good morning folks, I will be attending both of these events - Hamfest on the Friday and Convention on the Saturday, and will have my stock with me. I'm also happy to take pre-orders for

Hi Mike Its pretty easy to check on my web SDR .which is using an active loop that works OK at 60 kHz. Currently (Saturday AM) I have a strong signal from it. Mike

Here is the combined actiity list: Callsign: G8CUB/P Locator: IO81WU70 Birdlip, IO91CL12 Hackpen Bands: 24GHz 2W 30cm dish, 47GHz 30mW 30cm dish, 76GHz 50mW 150mm horn / 60cm dish Talkback: 144.175,

Hi Thank you for the 'calling'frequencies as once built I will only have 10 MHz of tuning Can any one suggest an easy method of getting a phase locked sig at 16,745.625 or14,885.000 Ghz For

Callsign: G3ZME/P Locator: IO82QL (Brown Clee). Possibly also IO82RP ('ZME bcn site) Bands: 24G and 76GHz (experimental) Talkback: 144.175 (preferred), 'KST, mob 07932 927 887

That is a good point. I also noticed that the part has a thermal resistance of more than 5 C/w. With around 20W dissipation that is about 100C temp rise. The gain is also very temp dependent from

Paul, General accepted 'calling' frequencies are: 24.048,1 47.088,1 75.976,1 134.400 ( was 134.928) Roger G8CUB

Just realised. I'm not going to be available on Sunday after all. 73 John

Will anyone be operating this weekend from the Shropshire / Powys area? I have a friend staying with me from the San Diego Microwave Group and it would be good to show him some of our stations /

Hi all could someone please help with the calling / working frequency that are currently being used and if there is any intention to change them The bands of interest are 24 , 47 , 76 , 135 Ghz

In a private email an amateur who is also makes jewellery suggests using silver alloy as the heat spreader, using the Delft Clay technique and casting using scrap silver. Alternatively it might be a

Thanks Eric, I did consider using a round slug for a prototype, drilling a round hole under the chip right through the copper base and pcb, so I could press it into place and get more contact area. I

>{I'm trying to work out if I can machine out a hollow in solid copper but leave a rectangular post in the centre the thickness of the PCB, then cut a rectangular hole in the centre of the PCB,

We have made some changes to the power system which will hopefully make GB3USK a more reliable service. However, we need to let the batteries recover their charge as they got rather depleted recently.

Nowadays, as nearly all MSF clocks only update at midnight, 0100, 0200 and 0300, the keepers of Anthorn no-doubt take this into account when doing maintenance, turning it back on during the night.

Thanks Andy, I have an Oregon Scientific clock which has a bargraphindicator of the signal strength and it has shown no change in signal strengthnor has the watch which has a dish shaped icon which

Hi, It's on - you can check anytime via the SUWS WEB SDR. http://websdr.suws.org.uk/ Regards, Martin - G8JNJ www.g8jnj.net www.tc2m.info http://websdr.suws.org.uk

It's on at the moment: my super antiquated Junghams Mega says so and it looks for a signal every hour. All modern MSF clocks only lock up once or twice in the middle of the night they so wouldn't
