I am in the US and would be interested in a 1.2 or 1.3 board if one is available. Thank you, Colin K6JTH

Hi Onno & Glenn, thanks very much for your feedback! At the moment I have a severe problem with my PC that I need to take care of first ... I'll respond asap ... 73 de wolf, dk1et

Thanks very much for the replies.? I thought about RF being the culprit, but the display was not coming on even when no RF was present.? The times when the display did work, it stayed on while I was

I even experience that with a manual tuner. My antenna is way too long to be used on 10-12 Meters. 15 is iffy. I get RF all over here, computer screens get interfered with, RFI into the stereo, etc.

Hi Jim, I have also experienced it. Especially when working 21-28MHz. The screen just goes dead-comes back after a restart. Something to do with RFI? Cheers! Tharanga/4S6TMP

The ATU-100 is now complete and functioning.? ?However, the OLED display has acted up from the beginning.? ?Sometimes it would come on, other times it wouldn't, without removing power and then

Hi Wolf, There shouldn't be any problem with relays in SWR measurment. The fact your reverse resistances are totally different and reversal of power in and out does not conform either means there is

Hi Wolf, Is the swr poor at all frequencies or does it vary per band? Looking at the bridge transformer confirms the could windings are correct. However I do notice one side has a significant "left

Hi Onno, thanks feedback. Enclosed some pictures, not very professional, but I hope they meet your request. I don‘t understand the context of bifilar / non-bifilar winding and basic malfunction of

Can you take a close up picture of the swr core and it's windings? I get the idea you might have non bifilar windings or something else. Op zo 20 mrt. 2022 16:16 schreef Wolf <dk1et@...>:

Hi Onno & Glenn, thanks very much for your advice! I followed your instructions with results as stated below. A note in advance regarding my dummy load: It‘s a home made one with SWR less than 1.1

I tried to get my raspberry pi zero to work in i2c slave mode and have now given up, it is too complicated to workaround the problem that still exists in the pi system. So, instead I am going to use

Thank you Mike. I learned a lot by posting the problem here. You all rock!! Tharanga/4S6TMP

Dr Jon, I have bought this one and made good experience with it: https://www.ebay.de/itm/393101317604 Advantage: it has a built-in Lithium battery (rechargeable via USB). Had much fun paired with my

The continuity you are seeing is the nature of the stockton bridge that's being used in the circuit and is normal. Your meter is using DC to test continuity but the circuit works at RF (AC). Not

Dear Tony, Thanks a lot for your quick response. I am relieved now. I will do some tests with the HF Rig and update this post for reference. Cheers!! 73 de 4S6TMP

Dear Wolf, You'll need two push-buttons connected to the mini-Jack plug (between the Ring and Tip - to the ground). Insert it into thr remote control's socket. Regards, Tony

Thanks for the info - Today I managed to set the ATU to auto mode by using a clip lead and a needle from ground to B1 - had to use a magnifier - and also found input and output short circuited - My

Ayubowan, dear Tharanga. Yes, this is as it should be: the windings in the Tandem Match transformer have an apparent "short-circuit" both to the ground and between the input and output? connectors.
