RE: [Elecraft] XV144 - another lesson

Hi Dave, Very pleased that you also share about your experience. How do you feel about the XV144 when compared with other V/U all mode transceivers? When you use your K2 to drive the XV144, do you use the K60XV? If not, what is your setting for drive level? 73 Johnny Siu VR2XMC From: d

Re: [Elecraft] Multimeter Altitude Limits

In our high altitude ballooning program at LSU (>120,000 feet) it's necessary to be very careful about sharp edges and corners in circuits of even modest voltages. Vacuum chamber testing is an essential part of the payload development. Our student payload had a Geiger-Muller tube, and that's a coup

RE: [Elecraft] Multimeter Altitude Limits

What's the upper voltage limit the DMM will handle? Resistors have a voltage rating as well as resistance and wattage (dissipation) ratings. We don't normally run into the voltage rating with leaded parts, especially with low-voltage solid state gear, but it's a very real concern as the voltage g

RE: [Elecraft] Multimeter Altitude Limits

Plasma displays have a 6500' limit. LCD displays shouldn't have the same limit, though I've seen specs on meters with LCD displays that say 6500'. So maybe it's not the display. Craig NZ0R -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Michael Napier Sen

Sounds like you have all the bases covered Chuck and it must be very frustrating! Just for your information, I use an IO Gear GUC232A USB to Serial adapter cable (around $30) and it works flawlessly with the KIO2 on the K2. I'm using it with various software programs including: HRDeluxe, N1M

Re: [Elecraft] Multimeter Altitude Limits

Hi Mike, i have taken my Fluke DMM up into the hills... No problems. The only altitude sensitive components might be the LCD and some DMM's have spark gaps which might short on AC prematurely at high elevation. i doubt there is any problem. i operate out of Cripple Creek frequently. Paul w0rw __

[Elecraft] Multimeter Altitude Limits

While searching for a decent DMM to use during my K2 construction I noticed several of them have an altitude limit of 2000m (~6500 feet). Since I live at 7,600 feet and frequent altitudes at 10,000 while camping I am concerned about this limit. A call to the Extech Tech Support line yielded a serv

RE: [Elecraft] No power output K2 Part III of assembly

Frank, It is unlikely that the transmit problem and the receive problem are directly related, but it is possible. I suggest that you ignore the receive problem until you resolve the lack of transmit - if they turn out to be related, the receive problem will also be fixed. On the transmit problem

John, Make R6 a 470 ohm just in case you ever add the K60XV option. The 470 ohm is shipped with the K60XV, but the value in the KAT2 is 47 ohms. Without the K60XV installed you can use either value. R6 is not installed until after some inital checks are completed - just follow the manual instruc
