I asked this before but it may have been too cryptically worded for a response, ha! I'm helping debug my AR brother's problem re uploading from QRZ to LoTW. To that end, I recollect having come across a mention of (and subsequently found) a local PC folder that contained a couple of error logs relating to failed LoTW uploads. I recollect those files were only pertinent to the last upload so are not present if the last LoTW upload was successful. I may have crossed-wired some neurons but am reasonably certain I stated it correctly. The fact that it is unusual for a web app like QRZ to deal with local files tends to make my certitude wane ;-) Anyone know if there is such a folder and, is so, what its path is? Thanks.
Sorry I do not know the answer to your question. I have had tons of problems in trying to upload QRZ log to TSQL then on to LoTW. I keep getting invalid key. But i know it is the correct key i put in QRZ to upload the Log.
