Re: [Elecraft] XVTR Out level

[Gary Johnson]

Sure enough, the BPFs are in the low-level RF path on TX and RX. Moral of the 
story is to choose a transverter with a 28 MHz IF when maximum usable frequency 
range is desired.

[Elecraft] Help on wiring up a XV144 to a KX3 (or KX2)

[Paul Gacek via Elecraft]

I would like to connect these two and am following the guidance in Fred Cady’s 
KX Line manual page 239 and details in the XV Owners Manual.

Wiring/connectivity is;
- KX3/KX2 RF out (28 MHz via BNC) connected to XV144 Tx In/IF1 port (single 
port for RX/TX).
- KX3 ACC2 connected to XV144 CONTROL DB9 port

KX3 transverter 6 is configured 
XV144 configured to be transverter 6 via instructions on page 5 of XV Owners 
Manual  (i.e as if the XV is connected to a K3 using the wiring outlined above.

Can someone confirm that this is the wiring I should;
- KX3 ACC2 TIP wired to pin 3 of XV CONTROL
- KX3 ACC2 SHIELD wired to pin 5 of XV CONTROL

Guess I’ll have to study the K3 block diagrams. For some reason I thought Xvrt 
Out didn’t go thru the BPFs.

[Elecraft] XVTR Out level

[w4sc]

At 15MHz you are starting to be out of the 20M passband filter, at 16MHz you 
are well out of the 20M pass band,,, the passband on 10M is around 2 or 3MHz 
wide and thus would provide the proper drive level for  144 (28MHz), 145 
(29MHz), and 146 (30MHz) MHz operation.

 From the K3 users manual, pp71:

Band-Pass Filters (BPFs)
At back-left is the bank of ham-band BPFs. These filters are just wide enough 
to cover each ham band, so they provide good rejection of IMD products during 
both transmit and receive. Hi-Q components, including large toroids, ensure low 
loss and high signal-handling capability.

[Elecraft] XVTR Out level

[Gary Johnson]

I'm testing the K3 XVTR output level for use with a Kuhne 144 
transverter (opt. 05) which uses a 14 MHz IF.


XV1 PWR is set to 1.5 mW as required. Checking with my spectrum 
analyzer, key-down CW output power at the XVTR Out jack varies as follows:


VFO=144 MHz (14.0 MHz out)  +1.3 dBm
145 (15.0)  -4.8
146 (16.0)  -17.5

Needless to say, the Kuhne output power varies proportionally. I also 
tested with XV1 IF set to 28 MHz and power output is flat. This 14 MHz 
level variation is unexpected; anyone seen this before?

[Elecraft] FOR SALE K2 SER#7750 REVISITED

[Robert 'RC' Conley]

When I decided to sell my Elecraft K2 #7750, it was after weeks of 
deliberation. Since I am relocating to a senior’s apartment complex and 
will not be allowed a traditional ham station set up, a choice had to be 
made: it was either keep my K2 #7750 or my KX2 #1098. I must confess it 
was a difficult choice. I decided on keeping the KX2, because I rather 
enjoy P.O.T.A. type operations. The KX2 being more self-contained made 
the choice easier. Using the Elecraft AX-1 antenna system also made set 
ups easier. I can carry the whole station in a Harbor Freight tool case. 
I have more mode choices with the exception of FT8. I enjoy RTTY  and CW 
more than FT8. The result: my Elecraft K2 #7750 has to go.


When I built K2 #7750 it was intended to be a CW only station with 
computer control so only the KIO2 option was included. I document all my 
builds. You can see the complete documented build on my web site at 
.


I had some issues with the build, so I sent it to Alan Wilcox who fixed 
the issue, aligned it, and also built and installed the KIO2 option for 
me. Then FT8 came along, so W5LA (Jim Ragsdale) built and installed the 
KSB2 option for me as I no longer felt qualified to do the work.


From Jan 24th until June 12th I made over 2,500 FT8 QSO's, including 
over 500 QSO's as a W5L special event station with K2 #7750 and various 
wire antennas: an 80/40 trap inverted vee and a 40/20 trap inverted vee 
@ 75'. All with this K2 #7750. Sideband operation is also available, 
however you will have to supply the

microphone.

I am offering my Elecraft K2 #7750 for sale for a reduced price of 
$700.00, including USPS Priority Mail shipping.


No need to clutter the reflector, so PLEASE reply off the list.

Re: [Elecraft] oh my. K1 woes

[Don Wilhelm]

Lloyd,

Pull the key plug out, then see if it stops.  If so, check the key and 
the plug.  The plug must be stereo and have the key connected only to 
the tip and the shell (no connection to the ring).

Re: [Elecraft] oh my. K1 woes

[LL]

yes .  Ray, K2ULR, set me right. What I needed, for using my little
Whiterook cootie, turned out to be a connector that was mono on one end,
and stereo on the other, which I had, in my go-bag.

[Elecraft] K4 to K4 remote question

[John Howell]

Wayne or Eric,

Is the feature enabling a K4 to control a remote K4 over the Internet
planned for the first shipment group, or is it more likely this feature
will be added later?

Thank you.

The MENU should be available with your key unplugged.  (If not you have much 
greater problems.)

Go to the MENU, find INP, change that to HND.

Then try your key again.
