Would an RF Explorer be good enough to gauge harmonics and spurious emissions?

Hi, I agree with Jerry. I have an RTL-SDR here. It's a fun toy. Signals from off the air overload it regularly. Never mind about being in the same room with a transmitter. It is not good for that kind

I believe the stock element is fine. I have tried other electrets elements and all delivered less output. I did change I believe R63 to have higher output. Some suggested to use very sensitive

Almost all of the land mobile (Motorola & Harris/GE/Ericsson/MaCom) are dynamic mics that have an internal preamp.? I've had an excellent experience using them in applications that were designed for

Curt thanks for reply .....I will have another look today when I have finished getting the mic attached to check out SSB first ..if that all works then back to the key ...CW is my preferred mode goes

Hi, Looking for a ubitx or bitx 40 contact me daveg0ayd@... i am located in the uk. Dave G0AYD. CW OPS 2159 FISTS 15892.

Possibly.? I'm using a -40db attenuation.? Think it needs more attenuation than that for RTL-SDR?

Agreed, spurs on 80m-20m are not a big issue with a stock uBitx. Harmonics on a stock rig are 30dB down or more, so down in power by a factor of 1000. Should be better, but I doubt anybody will ever

Dave There are more affordable options for the low pass filter mod, much less than the nice qrp labs relay board. Our club is using a board layed out by Gordon G. I would stand by until someone offers

Yep good ideas.? I'm also considering the daughter card filtering option.? Unfortunately I tried to buy from QRP labs but it didn't like my credit card for some reason.? Luckily they give

Geoff fantastic to have you aboard !? for CW - there isn't a specific mode.? for 40m - note rig will say LSB.? then press the key - display should read CW and you should hear sidetone.? if you got

Dave I suggest keeping this surgery within your comfort zone.? Nothing sacred about surface mount parts, but at 45 MHz keep connections short.? I am not yet considering this particular mod - but you

Good idea. Those amps are usually pretty small. Most I have seen are on a board about 2-in square. Bob — KK5R --------------------------------------------

Just got an eBay notice for this... https://www.ebay.com/i/163479080437?ul_noapp=true

Thanks Jerry, I am still looking for the best "Low buck" approach since another V4 followed me home and my V4 board is pretty well cut up. I thought the Axicom relay "fix" was not set in stone but if

Based on the recent v5 findings/design to replace R26 and add a filter L31, C205, L32

Ken VA3ABN, This is a very helpful file - I noticed it is page 22 (!) --- is this part of a larger document? Thank you!
