The PCBs have now been delivered, and I've made one up to test - works OK.

So sales of PCBs with programmed PICs  can now go live.

UK Purchasers will find a PayPal button on my website on these pages
Price is £9.00 for one. reducing progressively for up to 4
If you want more than 4, contact me.

If you want the NON-CW version, KEYER3  that sends sequential tones, please state this at the of ordering, the price is the same and you can have a mixture of types within the multiple-price.

NOW ............
Due to the faff/chaos/balls-up/megamess that is Brexit and the VAT changes, I can't add direct payment options for overseas purchasers (and this may even include GI, not too sure), so please contact me for more info.

I've got 100 PCBs , have 8 spare PIC devices ready to go with 50 more on order from RS - which should arrive tomorrow, but there could be delays.  

Now, off the post office for padded envelopes and stamps

All components needed apart from the voltage regulator can be obtained from the Chipbank if you're a member of UKuWG.   The board will work from 2.2V (although it is only supposed to be 2.5V minimum)  to an absolute maximum of 5.5V without the regulator.  (Perfect for a Li-ion cell)  Component values are supremely non-critical and quite amenable to your using whatever components are to hand.

Overseas orders, contact me for a price, but one sent just now to VK land  cost an additional £4.00 for standard non-tracked service.   Tracking option would have been around £9.00

Subject: [UKMicrowaves] PicKit3 Annoyance on close down

Ever since I got the latest version, the Standalone PicKit 3 software installed on my laptop Win 10 machine  always had this annoying habit of locking up with an error message whenever it was closed down.   The same thing didn't happen on my Win 7 desktop.  I mainly use the latter for programming PICs, so never tried to solve the problem - it didn't affect operation of the software, just ending it.

After Charlie G3WDG reported exactly the same issue on his Win7 installation, I thought it was worth investigating.   The error message reported that it "could not write to PicKit3.ini" in the  install folder.

The solution was to create a blank file of that name in the installation folder ( C:\Program Files (x86)\Microchip\PiCkit 3 v3\  or similar )  then run the PicKit3 S/W.   This time it closed down properly and saved the settings, including a last-used files list and various menu selections I prefer.

In order to avoid problems with 'Windows File Protection' which attempts to protect system files from unintended modification; I generally find is best to install most Amateur Radio and similar software in a directory other than Program Files. It also makes it easy to backup up the data and files associated with application programs. I generally create a directory C:\Radio and then install applications in there.

Re: [Scatterpoint] File /SP2012-A4.pdf uploaded #file-notice

Hello Ben,

This is not new. It has been in place since the MoD had to relocate some of their systems into the region around 2320MHz (we share much of the 13cm band with the MoD and they used to use parts we did not use until more spectrum was required by the mobile phone companies meaning the MoD had to move frequencies).

Details are required so that an amateur operator who causes interference to the MoD can be contacted quickly by OFCOM.

I live only a few km from Boscombe Down in Wiltshire and I have to comply with additional restrictions such that from May to October inclusive I can not operate on the 13cm band between sunrise and sunset on 'office' days, which for example means I miss up to the first hour and a half of the Tuesday UKAC SHF (13cm) contest.

I was once given a pair of SD1480 on a Band 2 PCB from someone who used to work at Eddystone radio, for use in a 144MHz PA.     I wasn't very successful at getting them going, but back in those days, the mid-to-late 1980s, hadn't got much in the way of test equipment.

Ben.
Yes we do, but it's not an NOV. I've had to do it for home location, my /A and /P locations in IO74. For 6 I put down "microwave propagation experiments".

It causes a bit of a problem for the SOTA 13cm enthusiasts with all the sites involved.

Airscout problems.....help!

Conrad, PA5Y
 

In the past I have happily run Airscout and SDR console on the same 64bit Windows 10 PC. I tried to use it last night and I observed 2 things.

  1. Airscout would not stay on top, it just kept minimising rendering it useless
  2. The graphics of SDR console were stuttering when Airscout was running. 
The PC is not in the least bit stressed and I have an CUDA Nvidia graphics card which is utilised by SDR console. I do not know what has happened. It was working last week and I do not recall any windows updates. Has anyone else observed this behaviour with airscout? I am using V1.3.3.0 of airscout.

Regards

Conrad PA5Y
