Hi Mike,
I'm not sure if the Key Out and key line on the Aux port are isolated or
not. At one time I had the KPA500, a tube amp, and a 2M amp for the
internal transverter all connected. I used a KRC2 band decoder
connected to a couple of relays that would switch the Key Out signal
among
Sorry for the somewhat off-topic post but this is the first time I have
heard the Eico 720 mentioned in decades. I happen to have one if anyone
is interested in buying it.

Hi:
I am thinking about purchasing a KPA500, as a backup amp as well as
having the ability to work 6m, but have a question about hooking it up.
Currently I have a tube amp hooked up to Antenna Port 1, and using
the Key out jack to key the amplifier. I also have a Microham MK2R+ hooked
up to
The charging scheme for the K2 internal battery is based on using an SLA
battery. If the battery is changed to another battery chemistry, the
charging circuit would have to be modified to match the charging
requirements of the replacement battery type.
Since Lithium batteries require very
My K3 key line runs to a Radio Shack breakout box that connects 3 amplifiers,
including a legal limit 6M unit, that are selected via a mechanical switch. I
believe I could have simply divided the Key line via two Y connectors to the
amps directly and skipped the breakout box if only only
Hi everyone.
Has anyone any experience or suggestions on replacing an aging internal K2
battery (the standard lead-acid type) with one of the newer, lighter and
more energy-dense batteries? I know there were some safety concerns with
lithium-based batteries early on, but now that they are are
All you need are diodes to isolate the keyout lines going to the amplifiers.
Just turn off the amp you aren't using. You can use a simple transistor switch
operated by DIGOUT1 to increase the current it can provide.
I would like to see Elecraft add the ability to control all the DIGOUT lines
I use a 4-cell LiFePO4 battery, with Anderson Power Pole pigtail, connected
externally to the K2. Easy to change batteries without having to open the rig,
and by recharging the battery external to the radio there is no risk of
engulfing my beloved K2 in a spectacular ball of flame.

I'm trying to set up my Elecraft kilo-3-sugar with FSK for the Roundup

on my computer. Every time I try to tell n1mm to use com1 for CW, PTT, or DIG
I'm told that com1 is in use by another program and is configured

Good Morning,
This is Mark Griffin, KB3Z. I have downloaded the most up to date copy of
MMTTY. I have setup my Digikeyer II to work with MMTTY. What is really weird is
that when I press the transmit button on MMTTY I have my K3 set to Data A, but
to see any ALC bars or get the normal RTTY noise
Please see the example configurations for Digikeyer II and MMTTY
and for Digikeyer II and N1MMLogger+ available in Router (Help |
Download Documents) or online in the Digikeyer II Support area of
the web site - www.microHAM-USA.com/support.html.
*BOTH* documents provide separate instructions
1. With the K3/K3S, FSK is *not* better than AFSK. In fact, before
firmware version 4.66 in March 2013, the K3's tranmitted signal in AFSK
was demonstrably cleaner than its signal in FSK. Now they are about equal.
2. If COM1 is a USB-to-serial adapter rather than a true serial port,

2. If COM1 is a USB-to-serial adapter rather than a true serial port,
then you will need to use EXTFSK with MMTTY; standard single-port
USB-to-serial adapters cannot go slowly enough to do 45.45 baud RTTY.
If you have hardware that forces you to use EXTFSK, locate and download
