Hi Jerry, What do you mean by "Be very careful about setting those pots to "a lot more" than 100ma,? that's a good way to make the IRF510's pop from the heat." What's? a lot more? I found I needed

I have checked all domestic sources of RD16HHF1 and for a quantity of 4, Polida2008 beats them all for price. They will get my order. Thanks for the recommendation.

Hi Norm, if you go to http://ubitx.net/ about the 7th line down, click on manual. Rod KM6SN

Sold! Thank you!

Hello, In Europe, you can order to https://sdr-kits.net/index.php?route=web/pages&page_id=55_55 ( https://sdr-kits.net/index.php?route=web/pages&page_id=55_55 ) but this is not the price of an IRF510

There is such a place. ZL1AXG puts in about 23 hours a day at http://ubitx.net/ ( http://ubitx.net/ ) look for KD8CEC on the link above ? -- www.bitxmap.com ( http://www.bitxmap.com )

I hooked up a calibrated signal source and verified that I can receive a 1uv signal on all bands.? This is consistent with performance of most modern rigs.? I find the rig a bit difficult to tune

I built a fully featured Elecraft K2 a few years back.? It has a variable bandwidth crystal ladder filter.? I wonder if the uBitx filter can be adapted to vary it's bandwidth in a similar fashion,

If you aren't seeing any power drain and you are still in receive then the first place to start is at K1. Check the voltage at the base of Q15 to see if it changes when you press the PTT. If it does

I used the same NESCAF filter and am very happy with it.? I have not tried it on contest conditions yet but for casual operation it has given a big improvement.?? Mark KC4GIA

On 80m/40m/20m the ubitx receives as well as my FTDX3000. Those bands, esp 80m/40m, are noise limited not sensitivity limited. The 3000, of course, has more filter options which helps control received

In Europe MRF510 can be bought from Conrad electronics, brand Vishy, for 50 cent plus shipping. Unfortunately they do not offer RD16.

Bill Thanks. Sounds like something I might want to try next time I have the mainboard out of the case. tim ab0wr "K9HZ" <bill@...> wrote:

The narrow audio response is either a crystal filter bandwidth issue or the bfo setting. The new firmware that we are talking about does NOT entail any hardware changes. It fixes things that are

Dave perhaps I should have said drive level, reports I got have been that the audio is narrow in frequency response Walt VE7CWS

I have followed all the KD8CEC uBITX sketch videos from the begining ( I do wish Dr Lee would put some sound guidance into these videos). There is a lot in the sketch that many of us still don't

ve7cws, What would you change about the mic? Almost every one I have talked to on the radio, says that it has a good sounding audio quality on both the 40 and the micro. 73 dave k0mbt
