Thank you very much Chris! I appreciate it. Best wishes, Guy

Hi Guy, We shipped a kit out to you by letter post but quite a few have gone missing. I'll send another one today as a small parcel in a padded bag. Regards, Chris

Hi Chris, Would you mind checking to see if my upgrade kit has shipped yet? I requested one in mid-January, for a VLF/HF loop that was purchased and received in December. I sent you a private message

The Loop Antenna Amplifier is to be reviewed in the Radio User magazine. They have also posted a preview on the Radio Enthusiast web site that covers Radio User and Practical Wireless

When I designed the Loop Antenna Amplifier it was intended to compete with the MLA-30 loop antenna on price. To keep the cost down while still keeping the polycarbonate outdoor enclosure I decided to

If you are using a shielded loop then the Loop Antenna Amplifier head unit PCB can be mounted in a shielded metal enclosure. The head unit has two separate grounds separated by a common mode filter.

Chris, I'm planning to use my recently aquired loop outside with a large coax based shielded loop. I'm also planning to remount both PCB's in cast aluminum enclosures which are both just large enough

Chris, Just a quick note - the vertical dipole is working splendidly on 30m Rx (not too shabby on 160 either). I've never worked Tx on 30m before, so my project this weekend is to finally cut a dipole

I have one of this exact supply, bought on Amazon. I use it for "smoke-testing" newly-built gadgets, GPS receivers, soundcard interfaces, etc. Since the current is far more limited than

What exact ferrite cores are you using on the leads of the supply you are selling? How much effect do they have on noise at HF and VHF? Stephen H. Smith wa8lmf

At that current I would be tempted to run a pack of AA cells for the ultimate quiet power supply. I doubt you will find a "modern" power supply as quiet. David G3UNA

Thank you Chris. My order will be on the way momentarily. :-) Ed -- Ed Pusey esptwo@...

Be careful the power supply you get does not create EMI or RF interference noise ... it will kill the signal

Hi Ed, The DC connector is a 2.1mm socket. The supplied connector will fit but it is a tight fit. Before dispatch it was tested with the cable supplied to confirm that both Preselector and cable were

Friends, I just received my HF preselector. It included a power connector cable without power supply. The connector is either not the correct size, or it is really, really tight, so I have not tried

Hi Chris all arrived safely and working well. Just awaiting set of aerial poles which should give me about 12 ft above roof level to bottom of aerial, as it's an upstairs flat that's a fair

My address has not changed since I received the first shipment. If you send it to the shipping address I should get.

Hi All This is not a "loaded" question. I DO understand that some have had problems with upgrading their original VLF/HF amplifiers and do sympathise. However, may I ask whether anyone who has

Btw Chris - Thanks for the upgrade kit you sent out recently. You sent me another by mistake the other day! I received a card from Royal Mail informing me a package was waiting for me but they

Stephen, We have already sent two kits out to you by letter post. It's possible that they may have gone by surface mail to the United States. Can you confirm that your address hasn't changed as we are
