Another cool thing is you can record yourself for playback, an easier comparison than trying to listen to yourself after a short delay. I know when I try to listen myself directly I get

Ah Thanks.? Ok I guess I still have a lot to learn about desoldering :) The needle is an interesting idea.? If I was going to do a lot of through hole desoldering I would probably try that hakko

Exactly it is sensitive enough as tabletops or portables (degen 1103, Sangean 909 etc). The difference may be in other characteristics, like blocking, the presence of BPF, signal handling, but as for

Hi get a long bolt, use a nut washer and spring washer to fix it to the case, then use another nut etc adjusted to the level of the other standoffs and use another nut etc to lock the

Agree. That's why I set the R8 without a preamp like the μbitx. Re more audio on the R8 it was to explain on the different audio levels between the two receivers and a hint for those who would like

I agree that the drill is a bad idea because it might drill out the plated-through hole. I have an old ice pick that serves me as would a darning needle. It's iron and the solder does not stick to

Ok thank you David I'm waiting for your answer, I saw this support in a post with k8cec and the laserbeam over, it thanks jo?l f6cht.

Yep I just figured I would do the rest for good measure... though didn't realize how bad I was at desoldering. To amend my previous statement it took vaccum desolderer, braid and a jewelers hand

Martin, Just to double check, the mic is just an electret mic like the picture below.? I don't have one in front of me to measure but it is approximately 10mm in diameter. -- www.bitxmap.com (

Martin scrounge whatever hardware you can for assembly.? if you don't like this plan, there are several fine suppliers of cases aka enclosures available.? if you have a 'surplus. electret based

Lawrence Good data!? Please notice that sensitivity relates to our ability to copy a signal in the background (and rig supplied) noise -- not how much audio the receiver can pump into the air.? yes

I've been admiring my bitx40 for a while, nice looking board. Finally, I knuckled under to build it and found a couble of problems. 1. no mike. 2. One standoff has no threads - it

Hi This morning I had an hour to spare so I switched on the μbitx and there was good propagation on 18 MHz. So I switched on the Drake R8 to compare the signals. The R8 agc was set to off as the

The ?BITX is working well on FT-8! ? Now it has a QRP Kits Easy TR Switch flipping between the ?B for TX and a SDRplay RSP1A on SDRuno for RX.? The WSJT-X software controls the ?B via USB using

Hi Gary, Your antenna comparison did not take into account where each antenna have it's lobes. For some stations one will work better and for other stations the opposite one will be better. It

A couple of days ago I had an interesting qso with K9BHP (Ben) using my ubitx. Ben called CQ on 20 meters from Chicago and I answered him with my ubitx running at 7 watts from Austin, TX. He gave me
