By the way, I have never been able to find any benefit from NR or
NB in a contest environment. Maybe my particular noises are
uncooperative, or maybe I need to try even harder to find a good
setting. I have read the advice, and have tried the recommended
settings.

Hi Ron,
Hi had a similar problem some months ago.
Symptoms:
Suddenly loss of sensitivity ~ -20 to -40dB or more...
Transmission was always ok.
Measurement with miniVNA always correct (at ~0dBm power).
Moving some connections remove sometimes the loss of sensitivity.
(but all soldered or crimped
Dave,
I use NR 'most' of the time on 5-2 for SSB. My ears find it better to
understand etc.
I usually adjust Hi/Lo cut to give me a nice rounded audio. I suffer from
Tinitus so my ears are not the greatest :-(
I also find I my bandwidth ends up around 1.7 to 1.9 and I have the 2.8 and
1.8
I wasn't going to reply on the coax connector issue, but how I know
that Amphenol UHF connectors are best is from 15-years of commercial
use in Marine Electronics. They solder better and do not fail like
cheaper manufacturer's. We tried saving some money using RS
connectors in the beginning
Dear Gang:
I've been playing with different battery packs for my KX1 and K1 lately, and I

I tested my KX1 key down with various battery packs and noted the output. This

Hello elecrafters
How to open n1mm and k3 utility at same time?
W i try to do thar a msg on n1mm comes: port 2 already open.
The reason i´m trying to do that is use the F buttons set by MACROS keys
on k3 utility running on n1mm.
Tnx for any help.

Hi All,
I've just finished K2/100 #6998. After blowing the PA transistors of the
base K2 by accidentally dropping the frequency probe into the works, I've
completed the KPA100, installed it and all is working very well. Made
several SSB contacts tonight and I couldn't be happier. I have a

You do not need to use the K3 utility - you only need to set up N1MM
properly.
The info to do so is here:

I have had good luck lately with AA cells from PowerGenix.
They are Nickel-Zinc, and start at 1.83 volts fully charged and are

With 6 of them in my KX1, the internal voltage was about 10.8 volts.
They don't have as good self discharge (about 10%/month) as the Lithium

I have not discovered the source of that birdie, but it is there.

Hi John,
Glad to hear that after all of your bad luck your K2/100 is now working
well.
The strong birdie at 3589 kHz was also present in my K2/100 before I
embarked on a birdie killing project a few years ago, which involved a fair

DS command byte 2, bit 2 reflects the NR icon state, which will
normally be the MAIN NR but is SUB NR in BSET mode with the sub on.
IC command reports sub receiver NR status in byte e, bit 2.

Hi Tom,
To test the value of bit 0 in an 8-bit variable X in C, you can use
the bitwise AND operator ():

0b1 is a binary constant that's the equivalent of a byte with only bit
0 set. It is used by the operator as a mask. If bit 0 of byte X is

Stan,
For an unregulated supply, try this MPJA unit -

You will probably want an enclosure, so look in the left side of the

Or purchase a transformer, a bridge rectifier and a capacitor and build
