Re: [Elecraft] Transverters?
Gil, The Elecraft XV series transverters were designed to interface with the K2, and then extended to the K3. If your K2 includes the K60XV option with its 1 mW TX and RX connections, the operation is seamless. The K60XV transceiver ports connect to the transverter and the HF antenna connections can stay in place. Without the K60XV, operation is still great, the transverter will accept up to an 8 watt input signal from the K2 high power output, but you will have to switch between the connection to the transverter and to the HF antenna. Once that hurdle is passed, the operation is again seamless. The K2 TRN menus allow you to set up the frequency display as you want it (including any offsets). 73, Don W3FPR On 9/8/2012 9:11 PM, Gil G. wrote: Thanks Ray, I should have mentioned that I was considering a 2m Elecraft transverter for my K2...

Phil, It sounds like you have either the frequency offset or the IF frequency currently set to 14.000 MHz - something to check out.

Re: [Elecraft] Transverters
Hi Kevin, I designed the XV transverters for Elecraft and will attempt to answer your question. Receiver design always requires some compromise between sensitivity and dynamic range. To maximize sensitivity, lossy elements, like filters, are moved farther away from the antenna to minimize their effect on noise figure. Sufficient gain is also provided to minimize the effect of the noise figure of the following stages of the receiver which in this case is the transceiver used with the transverter. To maximize dynamic range, the receiver designer would do just the opposite. Selectivity would be placed as close to the receiver input as possible and gain would be minimized. The XV transverters in standard configuraton attempt to balance these requirements in a way that is optimum for most users. We do recognize that there are situations such as very high interference environments or when external preamps are used, or when a very low noise figure IF transceiver is used, where the standard configuration is no longer optimum. It is for this reason that the manual includes instructions to remove the ERA amplifier from the signal path to reduce the gain of the receiver ahead of the narrowband filters. 73, Bob, N6CM - Original Message - From: Kevin Murphy [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Wednesday, April 05, 2006 12:34 AM Subject: [Elecraft] Transverters Hi, I notice a trend with the Elecraft transverters, in that there is a second RF device, such as a ERA or MAV MMIC following the 1st RF RX device. With most other designs I have seen, there is a filter between the 1st and second RF amplifier stages to limit out of band signals being amplified by the second RF stage. In rural areas there is a lesser need for out of band filtering, but in suburbia there are many out of band signals. Comments please?

Re: [Elecraft] Transverters
The transverters are excellent. Easy to build and awesome performance. I ordered my first Elecraft product, a XV144 - the 2m transverter, a week ago. Took just a few hours to assemble it, and it was easy to align and setup. I have done a fair bit of kit building and home brewing (DSP10, Tandem Match, KK7B R1 and R2, and others). This is smoothest kit yet. And in Elecraft tradition, the outcome is world class. Just see the review of the transverter in October's QST Product Review. It beats the Down East Transverter hands down and measures up to the gold standard - the SSB LT2S which cost $900 (and is not available any more.) The closest commercial competitor today is DB6NT's TR144H that costs a $1,000 Euro - about $1,200 and its still incomplete (needs special options/parts to work with low power transverter outputs like that from Yaesu 1KMP, provide IF swithcing, etc). I am so impressed with Elecraft's transverter that just after building the XV144, I ordered the XV222. Can't wait for the XV432. If only I could rig up a pan adapter for the K2, I'd use that as an IF rig instead of the Kenwood 850. I guess I've joined the family of Elecraft fans.

Re: [Elecraft] Transverters
If only I could rig up a pan adapter for the K2, I'd use that as an IF rig instead of the Kenwood 850. Raj, As an alternative, N4PY's software control program has a bandscan function, that when you press it, it takes over the K2 for about 10 seconds, and scans the bandwidth you want, and shows the display on a quasi-spectrum analyzer screen shot. Works very well. http://www.ralabs.com/n4py/ Also, on six meters, I have an older Icom 551D. The receiver blows wind, but it transmits OK. Receive audio is just oh so bad! In looking at the Icom diagram, the IF shift uses a 10.xx MHz IF. Hmm. So I tapped that feed, and ran that to my K2, which picked up the IF signal on the 10 MHz band. Now I have the clean K2 receive audio. Basically, I tune with the Icom, and transmit with it, but receive on the K2. Kinda weird, but it works. I'm saving up the nickels to buy another K2 ( so I can be on six and the low bands at the same time), and of course a Elecraft six meter transverter. And for Elecrafts next item: Oh would I like a box that taps the K2 IF, and is a spectrum analyzer. The output would be VGA, to plug into your monitor, or USB/UTP connection. That UTP connection would also tie into the K2 rs-232 for control across any network. (UTP connectors with built in web browers are around $ 40 today) Someday, 73, Tom K8IIE ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Transverters
Hi Make sure you are using the BNC on the right (J3) when looking at the back for the TX IF in and the one on the left (J2) for the RX IF out. The silk screen is backwards on some of the rear panels and there may be a little label over the original silk screen with the correct information on it. I have two early XVxxx and the silkscreen was backwards on both of them. You can order the correct label from Elecraft. Obviously the transverter will not work if the IF cables are reversed. This had me going in circles on one I built recently. When using the transverter with a single TX/RX cable J2 and J3 are connected together so it does not matter which one you use. But when using separate TX and RX cables the paths are split and J2 must be used for the RX and J3 for the TX. The BNC tees will need to mount at a 45 degree angle and you will need to make up several short 3-6 inch coax jumpers to use to connect the transverter stack. You will also need to make a pair of BNC to RCA cables 2-3 feet to connect the transverter stack to the K2/XV60M Don Brown KD5NDB - Original Message - From: Paulmailto:[EMAIL PROTECTED] To: Elecraft@mailman.qth.netmailto:Elecraft@mailman.qth.net Sent: Tuesday, July 06, 2004 9:19 PM Subject: [Elecraft] Transverters Reflector Members and specifically: Simon Lewis Don Brown Eric Swartz Thank you for the help on the transverters.

Yesterday, using the AB switch, the incoming signal volume worked fine and now there is hardly and audible signal and no reading or just barely an S1 bar on incoming signals.

Can any of you offer some insight into where I might start my troubleshooting on this FYI : I am using the diagram on page 66 of the transverter manual and I used the jumper setting for -20 dBm(.01) to 0 dBm(1 mW) which is listed as the following connections: JP1: 1-2 JP2: 2-3 JP3: 1-2 JP4: 1-2 JP5: 2-3 JP6 2-3 This XV144 is deaf as can be now.. and it was not with the High RF output and an AB switch. So I have missed something somewhere! XV 50 is low audio too. By the way - How do you get those BNC T-connectors to fit back there. I had to use them in the vertical positon and then set the transverters on a book so they did not bend the wires coming out of the bottom of the T-connector when hooked up to the transverters. Are you using a special BNC designed T connector that fits back there?

RE: [Elecraft] Transverters
Paul, I would never recommend such a device if your a serious VHFr They leak and will pick up alot of external signals that are not on VHF! I think a famous DX record in the UK was claimed by two 28 MHz drivers and leaky connections in the 70s! I would only recommend good solid cables and connectors and no switch if your wanting your system to remain at the best performance. The A/B type switches are generally not good and will leak signal across the switch ports. You can use the offset command in the K2 menu to trim the transverter onto an accurate external signal - as long as your really sure that your are 100Hz off!!! dont rely on the local beacon ;-) regards Simon DL4PLM/GM4PLM From: Paul [EMAIL PROTECTED] To: Elecraft@mailman.qth.net Subject: [Elecraft] Transverters Date: Tue, 6 Jul 2004 09:31:22 -0400 Reflector Members, Those of you using Elecraft TransvertersAre all of you using an A/B type switch to go from HF to VHF on the K2' transverter hookup?

Re: [Elecraft] Transverters
HI Yes if you install the KX60M option then the switching is not required on the antenna because the K2 RF is not required to drive the transverter. The drive comes from the low level output on the KX60M not the K2 finals. The K2 output circuit is turned off when the transverter is selected on the band switch and low level drive is selected in the menu. The XV144/222 does not have a frequency adjustment for the local oscillator (although the XV50 does) There is an offset adjustment in the K2 transverter menu to compensate for slight frequency variations. This will allow you to adjust the K2 dial indicator to the correct frequency for your transverter. Each of the six transverter menu selections have their own offset setting.

Re: [Elecraft] Transverters
Hi Paul, We also offer the K60XV internal transverter interface option for the K2. It has a separate low level output for the driving transverters and automatically switches to that output from the K2's HF output when you select a transverter band. To correct for the 100 Hz offset go into the K2's transverter menu area. There is a +/- offset setting that will compensate for this. 73, Eric WA6HHQ - Paul wrote: Reflector Members, Those of you using Elecraft TransvertersAre all of you using an A/B type switch to go from HF to VHF on the K2' transverter hookup?
