Has anyone got a 23cm transverter they want to sell? Rich G8ZHA

Thanks for the info, I will go ahead and purchase a black PCB – they are also the cheapest. Rich

I was just looking on ebay, to purchase a ADF4351 PCB. I note that the majority of available PCBs are darl coloured, with a 2 * 5 way header connector. A while ago most of the PCBs were green with a s

Sam, Is your DG8 Preamp just contained in a plastic waterproof box? Does it need any extra shielding in hi RF areas? Regards, Rich G8ZHA

For info, I have solved my noise issue from my HiSpec LED lights. I have replaced the drivers with a Meanwell APC-12-350, at a cost of £13 each. Equal to the cost of the Hispec light and driver, so yo

I have built a couple of W1GHz projects: a GPS locked 10MHz osillator and a 100MHz PLL board. Each of his circuits uses a LT1116 hi speed comparator to lift the oscilator signal up to 5V CMOS logic le

Just what I need. Many thanks. Rich.

I am looking for a suitable box for a mast mounted preamp. One such as the SHF-Electroink type as shown on the attached picture. I did manage to pick one up from a rally a few years ago – does anyone

Another mast related question. When a pump up mast is used on a outside broadcast van, for instance, the coax is wrapped around the mast and when the mast is lowered, the coax forms its self into a ci

Could I ask.....do you leave the masts pumped up for extended periods? Rich

Thanks for all the replies about the pump up masts. Could I ask about mounting them on a wall. The attached pic shows the rear of my new shack. The corner is built from 440 * 210 * 100 concrete blocks

For my new shack, I have been thinking about getting a pump up mast, which would need to be at least 6m tall. It would need to be wall mounted and the initial payload would be an AZ & EL rotator, with

AD also do a VHF/UHF version, somewhat cheaper. I just want some software that will allow me to specify a number of bytes to be sent, then to allow me to load up the bytes and send them.

I wonder if anyone knows if there is any software about that can control a device connected via an SPI bus. There are small compass modules available that are SPI controlled. Along with various PLL mo

I have just sent an email to Mini-kits in VK, enquiring about a couple of PCBs and received this reply: Sorry we can no longer ship to the UK due to changes to your tax system. https://www.minikits.co

The CAN bus is widely used in industrial automation, controlling drives and HMIs on large machines and plant. The main problem is that there are no set standards of commands. Each manufacturer goes th

The 12V to 5V is a 7805 linear reg, but the 12V is probably via a SMPS. I will make sure I have some filtering on the 12V input at the preamp. Rich

I have just built a G4DDK PGA-103 preamp to use for ADSB receive on 1090MHz. The preamp will be mounted up on a pole, directly underneath a PCB antenna, in a plastic tube. I feed 12V up to the preamp

Sorry to mislead you…….the ifr2025 works fine. Very clean. Its just the packaging could have been better. Rich

I bought a IFR 2025 from the last auction. Fast delivery once it was paid for, packed adequately, not perfect but it is all working in the end. The final price was a bit of a shock though, with the 15
