AA4PB Audio Interface: Any advice? NV2K on 19/12/17
Here's an update: The connection labelled "Line In" is actually the line out, and vice-versa. I do not know what the impact will be of having swapped the primaries and secondaries of the transformers because of this, but suspect it will be small if not non-existent because they are 1:1 and are used for isolation only.

I would like to get the PTT from the right audio channel, as very few computers these days are equipped with a TIA-232 serial interface.
eBabel.net another confirmation process K4WY on 2/3/17
If you wish to try this service, I hope you have better success than I do.

There are no instructions to speak of, the process does not appear to be intuitive, and there are very few users. I have several matched QSLs there, yet no confirmations. I am at a complete loss as to why this is so.

Good luck confirming V43.
Attic Antennas apr1350 on 23/7/16
Without a ton of loading, a wire that fits into the typical attic won't do much on top band, and, agressively loaded, the 2:1 SWR bandwidth will be painfully narrow, and most radiation would be near-vertical. Those who say it won't work might be right -- about 160m. I hope that's not a deal-breaker for you!

Simple wire antennas often pleasantly surprise me. If you can make more than one excursion to the attic, how about hanging a simple dipole for 14MHz as a test? 33 feet, from end to end, with a SO-239 in the middle. Try an A/B comparison with the vertical, keeping in mind that lately there has been a lot of QSB on 20m. This can at least tell you if there's enough metal flashing, chimneys, etc., to keep your signal from getting out.

For anyone interested I received the plague 6/01/15 from UPS.


I wish you a speedy and complete recovery, OM!
Flash player Making site unusable KBurton on 27/5/16
Flash has security holes and is basically an end-of-life product. PDF and DJVU are good formats for e-mag versions of print magazines and today are trivial to generate.
