Hi Alex, Is there such a position and if so, where is it? 73 Marco Von: sharedapexloop@groups.io <sharedapexloop@groups.io> Im Auftrag von Alex Tkatch via groups.io Gesendet: Samstag, 4. Dezember 2021

Hello Mark, we tested the AS-SAL30 today with the original amplifier as well as with the amplifier you delivered in mid-September. With both amplifiers, strong intermodulation products are created her

Sorry, the first link is invalid. Here is a better one: https://nextcloud.csww.de/s/s3BBkA7FAGE7Mna The first part is real, the second is full of intermodulation products. Von: sharedapexloop@...

Hello Apex friends! We have severe problems with the Apex-30 here in Germany due to intermodulation interference. We don't have these problems when using an Apex-12. Can it make sense to reduce the fe

We will continue to test and measure in August. By the way, with a K9AY antenna we did not have any mixed products (ghost signals) on the same receivers and place. Best regards Marco Steiner

Mark, Would it be possible to produce an amplifier board on which you can switch the amplification in 3 or 4 stages by means of switches or jumpers? Best regards Marco Steiner

Hello Gedas and Mark, the antenna is unfortunately dismantled again. It is a weekend house and the property belongs to the farmer. In August we will rebuild it and carry out further tests, also with a

Hi Mark, At first the high-pass filter was active, then we deactivated it. But that had no influence on the mixed products (ghost signals). Best regards Marco Steiner

Hi All, The problem is not the RX. We also have a Rohde & Schwarz EK895 and a Telefunken E1700 in operation. The mixed products can also be heard there. Best regards Marco Steiner

Hello Mark and everyone else here! Many thanks for your help. Here are a few screenshots of the mixed products (ghost signals) that are generated. The problem occurs mainly in the early evening hours

Is it sufficient if the amplifier is removed to connect PIN 1 and 2 with PIN 9 and 10? Best regards, Marco Steiner

Hello everyone, thanks for your quick replies. Is it possible to simply remove the amplifier board and operate the antenna without it? Do any bridges need to be installed? We'd like to try this out wi

Hi All! I am a new owner of an AS-SAL-30 Mark II. I built it 3 days ago, bought from DL6EAT. The antenna actually works perfectly, but it generates very strong ghost signals of 0-30 MHz. It is not due
