[Elecraft] XV432 transverter note

Hello fellow owners, I am posting this here in case it may help others solve some issues they have. The past weekend contest presented a good opportunity to test a recent modification to my Elecraft XV432 transverter. In the last contest I noticed that its frequency stability was not sufficient

Re: [Elecraft] XV432

Due to station changes I have a stack of 5 Elecraft transverters sitting idle. (There are still 3 others in use!). 50, 2x 144, 222, and 432. All but the 50MHz one are converted to use external LO. They are easily switched back to the internal LO if desired by soldering back a few

Re: [Elecraft] XV432

I have used it for JT65 and FT8 but you have to run it at low output to minimize drift from heating. Even with the oven option it will drift as it heats up. I eventually changed my entire stack(144,222,43,902,1296) all to an external shared programmable LO, and that was connected to a 10MHz

[Elecraft] XV432 Frequency and Power Stability

Hi All, I finished assembling a XV432 transverter and seem to have a little problem with both power and frequency stability. After going through the alignment steps, the power starts dropping from 20W down to about 10 after sending CW into a dummy load for 20 seconds or so. During this time,

[Elecraft] XV432 - users' comments

Hello Group. In response to my earlier email asking for the above, I have received one reply so far. Anyway, my second K3 has already been shipped so that it is now no point to place an order for xv432 in order to save shipping costs. Thanks for your time in reading my post. 73 Johnny Siu

[Elecraft] XV432 low output power

Hi Folks, I wonder if I can pick the collective brain about my XV432 which has low power output. I am driving the transverter with my K2 and the XV60. This is all fine as my XV144 performs perfectly. The problem is in my XV432. Key down I get about 7W output for the first second or so then

[Elecraft] XV432, Q1...

Hi List, I soldered faster than I read. So Q1 is now installed in a common fashion without teflon spacer. Leads are clipped. What am I going to do now? If the teflon is just for spacing I would remove the Q, prolong the leads and install it without the teflon but spaced (I think the teflon

[Elecraft] XV432 on the air!

Finally got around to building the XV432 this weekend .. pretty much goes together just like the other XV's, took me about 6 hours. Fired up just fine, got it tweaked and on the air last evening. I'll be drilling the prototype combination end-panel this evening, and if all goes well I'll post a

Re: [Elecraft] XV432 added to order page; New XV Data Sheet

Slight follow-on, the IC-7800 has (from memory) full RX up to 50 MHz or so. I'm not looking at using terrestrial 70cms at the moment, but no doubt this will happen at some time (who knows). With luck I'll have the IC-7000 in a few months, so for simplex 2m / 70cms this is the easier and (very

RE: [Elecraft] XV432 added to order page; New XV Data Sheet

Simon, Since the IF is stated to be 28 to 32 MHz, I believe that translates into a receive range of 432 to 436 MHz. I recall something being said earlier about an optional crystal frequency for a different range, but I see nothing about that in the XV data sheet. 73, Don W3FPR -Original

Re: [Elecraft] XV432 added to order page; New XV Data Sheet

Hi, I just printed out the XV flyer (on my new OKI C5250 colour printer). Didn't see this info about the IF - I wonder if my IC-7800 will TX between 30 and 32 MHz in transverter mode - guess I'll have to ask around. I usually just listen anyway, rarely transmit. Simon Brown ---
