Wow! I’ve alsways wondered about putting some lightning arrestors for my wire antennas but never have. Perhaps it’s time to do so. Curious anyone on the list do this w their wire antennas? My prob

Hi all, As well as a band tx inhibit modification (I too don’t have a resonant aerial for 30 metres or for 80 meters) an output to indicate what band is in use would be nice. Then I could use it to

Hi Greg, The short answer is I have tried multiple cables and multiple computers.? The only common thing is the anti-virus and malware software on them.? That is why I plan to try disabling the

Thanks for the responses As stated in OP, I'm using firmware 1-01.c - the three blinks should indicate that the QDX thinks it's transmitting. Also the current draw increases so something changes when

Please, Tell me like “NanoVNA for idiots”, as you would tell a child, how I use my NanoVNA to measure accurately the uH L values for the inductors going into my QDX. I might be able to figure it

Thank you for that info, Stan. Looks a bit meatier than I'm ever likely to need, but it would certainly do the job? :-) -- Julian, N4JO.

Thanks again for the info. The problem is a setting in L32. Got QDX working all ok with Logger32 Cherry Picker. Now need to find out where my missing 1Watt is! 73 Ian G4GIR

I am thinking that a close by lightning strike introduced a little bit of a voltage into the connection where my coax goes to the vertical ? Paul K2DB

Any thoughts about having an "@QRPLABS" or "@QRPQDX" callsign group? I've been lurking on JS8Call's 40m frequency. It's good to see Hans getting behind JS8Call, I see a lot of heartbeats but not much

Alan, I got similar results with mine at 24.999910 and it also appears stable. I’ve not seen them this far off before. Ron

I have a 40 qrp classic and a 20 meter classic for sale both have about 3 watts out and ill throw in a QGL1 GPS unit with free shipping to lower 48.

Hoping to give this a shot with my QDX, loads of FT8 contacts so far, just one Ft4, and so far no JS8Call :( Robbie de M1ROK

Now sold, thank you

New QDX owners may have an opportunity for QSO's with their counterparts here: /g/js8call/viewevent?eventid=1123335 Not mentioned on that particular page (but elsewhere): it starts at

Hi Julian, The EFHW I have is from KD8UJM on eBay ( https://www.ebay.com/itm/194033201769?hash=item2d2d47b269:g:M54AAOSwxodgdKhI ).? I wanted to get on the air so bought this one after some looking

I will admit to accidentally transmitting with 5 watts for 15" yesterday into no antenna at all. No damage to the QDX. -- John AE5X https://ae5x.blogspot.com

Phil No, although in the past such enquiries have prompted the description of many other methods, and possible disadvantages :-) 73 Alan G4ZFQ

Hi Jay, did you mean to say R27 and not R37?? If it is R27 you are referring to, that's part of a filter/amplifier circuit for the I/Q signals.? That resistor should only affect receiver

Hi there, As I would like to use my QDX portable, can any one see any problems hot glueing the toroids to make the QDX a bit more rugged? cheers Phil G8PJH

Catched a fault when using JS8CALL. I have ferrite nr. 31 on all cables. Maybe next I will test a few hours with only a dummy load. @Hans, in the log function, would a counter as timestamp be
