[Elecraft] transverter reports? - KX1 radio

[Don Brown]

Hi

I built a 6 meter and 2 meter in the field test program. I sold the 2 =
meter and have another 2 meter to build to replace it. They are both =
beautiful radios. The mechanical and electronic design is the best I =
have seen and I have built Tentec and DEM transverters for both bands. =
They perfectly match and integrate well with the K2. I get good reports =
from both of them. They will also work with other radios for the IF. The =
2 meter I sold was modified for moon bounce and an external local =
oscillator derived from the GPS system clock. The last report I had, it =
was working well.

Go ahead and buy one you won't be sorry.=20

The kit is an easy build much like the KAT100 except there is only one =
toroid to wind. It should only take you 6 to 10 hours to build. There =
are a few surface mount parts but they are already installed on the =
board at Elecraft so they are not a problem. You can daisy chain two or =
all three of them with your K2/100 or K2 and the firmware will switch =
them in and out when the band is selected on the K2. The K2 can control =
3 of them connected with proper frequency readout on the K2 display. =
There is an optional crystal oven for improved local oscillator =
stability. You can configure the XV's for low level or high level RF =
input. They have a 8 watt load resistor built in for the high level =
option. You can also have a single output or split the transmit and =
receive. They also have a key output to drive the keying of an external =
amplifier. The XV will output about 20 watts and will operate in any =
mode the driving radio will provide. With the K2 that is CW and USB or =
LSB. You could use them with FM if the driving radio has that mode on =
the 10 meter band. During the field test several improvements were =
suggested that required a re-layout of the circuit board and that =
delayed the delivery a little. One improvement was a jumper to select =
powering down the local oscillator when the XV is not selected or =
leaving the oscillator powered up all the time for improved stability. =
This is the option you would want with the crystal oven.

I also just completed a KX1 S/N 0070 with all options. Wow What a neat =
little radio. Built it in about 10 hours including the 30 meter, antenna =
tuner and paddle options. As the XV above there are a few surface mount =
parts but they are also pre mounted. Another winner from Elecraft. For =
those of you wanting Elecraft to make a SWL radio this comes close. Last =
night I was listening to the BBC, several German stations and a bunch of =
ham SSB QSO's. The little radio's tuning is very nice and accurate. WWV =
is dead on after doing the calibration. The adjustable crystal filter is =
smooth and sounds good on both SSB and CW. The receiver is hot and =
considering the KX1 is only 1.5 times the size of an Altoids box it is =
amazing how much radio is in there. This is the perfect travel radio. =
The KX1, roll of wire and some earbud earphones and you are all set. =
Three band radio with 5.00 MHz to 16.00 MHz coverage. 1 to 3 watt CW ham =
band transmit and CW, USB and LSB on receive with a band pass filter =
adjustable from 300 to 2000 KHz. Built in batteries, automatic antenna =
tuner and even a flashlight...WOW

  Have we had any reports on building and using the Elecraft XV VHF=20
  transverters? Maybe I missed them?

  Early builders, please post reports. Inquiring minds want to know!
