Hi Mike, If you are planning to use the head unit of the Loop Antenna Amplifier with a SDRPlay receiver you will probably be better off with the HF/VHF version as the head unit has a higher gain. I ca

Hi Paul G, Can you check the coax cable you have running between the head unit and the base unit? You should be seeing far higher signal levels and I suspect that if one of the centre conductors or sh

Stephen, In the UK we have the Data Protection Act which covers customer data such as names, addresses, emails etc. While the idea of publishing a list of upgrade kits sent is a good one it runs the r

Hi John, The antenna and power supply is built and tested, it just needs the base unit completing this afternoon. This VLF/LF/HF Vertical antenna is one of the most labour-intensive products we manufa

Hi Paul, I think that I'm nearly up to date with the upgrade kit requests. I'll ship another one out to you today. Regards, Chris

Hi Paul, The upgrade kit has been posted out to you. We are shipping them via letter post so there are no tracking numbers. Another batch are being posted tomorrow. Regards, Chris

Thanks for the very kind comments, Kevin. Cross Country Wireless is our main business. We are always thankful for the feedback we get from customers. Making and testing a prototype in wet and rainy no

There is no need to modify any of the HF Active Loop antennas. The head unit amplifier of the HF/VHF version of the Loop Antenna Amplifier is almost identical to that in the HF Active Loop antenna. Re

The first batch of Loop Antenna Amplifier upgrade kits has been posted out. I've received many emails and posts so rather than answering the questions in each one individually it's best if I post the

We are now ready to dispatch upgrade kits for the VLF/HF and early versions of the Loop Antenna Amplifier. The kit consists of a transformer, a 1000 uF capacitor and two 82 pF capacitors. I've uploade

I'd made and edited the most perfect video. Unfortunately when watching the final version before putting it on YouTube we realised that my hands got in the way of the critical bits of soldering. I'll

Hi Ondrej, The Broadband Active Antenna has two wideband antenna elements with a very low noise amplifier directly at the antenna feed point so there is no feeder loss before the amplifier. This gives

We have recently stopped supporting Digital Messenger and APRS Messenger. I know that there is a problem with the program with sound card issues when used with Windows 10. Unfortunately the programmin

John, With the Christmas / New year holidays we have had problems with some of our suppliers and we have not been able to get a machined part for the Active Vertical Antenna you ordered. We should get

Kevin, Brent has the later HF/VHF version of the Loop Antenna Amplifier. This week I've been doing a lot of work testing changes to the VLF/HF version that you have and next week I'll release an upgra

The transformer mod will be easier to do. We will supply a transformer with 4 wires cut ready to solder to the head unit PCB and stainless steel studs. Regards, Chris

I've just been doing some more work on the VLF/HF version of the Loop Antenna Amplifier. It uses a direct coupled amplifier to extend the VLF coverage to less than 10 kHz. I've just modified two VLF/H

Paul, I'm back in the workshop and I've just tried the mod you made using the existing toroid core. As you have found it doesn't work very well as the toroid has too much loss. If you wait until I hav

It's not possible to easily convert a VLF/HF version to a HF/VHF unit. The reason for the recent Service Bulletin 4 modification was to bring the HF performance of the VLF/HF version up to the same le

Thanks for posting that, Brent. Good to see that it's working well for you. Just a few questions to confirm the comparison... What size loop are you using on the HF/VHF Loop Antenna Amplifier? Is the
