Second RX
Locked
 
|
Hi,
Had the chance to play with a Yaesu MP1000-M Mk.V (apologies for swearing) today and was most impressed with the functionality that the second RX path gives when working split. Never experienced that before. Other than that a bit OTT for me. Wouldn't it be nice to have a second RX module, rather like the external VFO of old, slaved to the main K2 chassis. Or maybe an interface module that enables another RX to be coupled to the K2 for common antenna feed, switching and muting. Something else I thought about was boots for the KX1. 20W or so would make it handy as a slightly more potent, holiday, restricted bands, mini rig. It would still be a pretty compact combo.

Just get a 2nd K2!
By "boots" I suspect you mean an amp, they're out there, the HFpack group has an amp in the works, I think you can buy the kit, and there are other kits out there. Our FCC in the US is very uneasy about anything that could be conceivably be used on CB, so HF QRP amps are not as common on the US market as they could be. 73 de Alex NS6Y On Apr 21, 2006, at 2:25 PM, Mike Harris wrote: > Hi, > > Had the chance to play with a Yaesu MP1000-M Mk.V (apologies for > swearing) > today and was most impressed with the functionality that the second RX > path gives when working split.

Regards, Mike VP8NO --------------------------- I'll bite! What does the MP1000 provide in split that the K2 doesn't provide in split mode? I run my K2 in split all the time so I can adjust the receiver as desired without messing with RIT and that tiny little knob. If you have access to old QSTs, Doug DeMaw's "Boots for the HW-8" in the June '79 issue would be a perfect match for the KX1. I built one for my HW-8 using plug-in output filter modules to work 40/30/20 meters. Takes about 1 to 2 watts input and puts out 15 watts. Simple one-transistor design. I don't use mine with my KX1 (well, there's a K2/100 sitting on the operating desk...). I gave it to a buddy who wanted a little more oomph for his HW-8.

With holding "REV" and tuning split TX freq you often miss the point when DX gives "TU" and starts to listen for next one. I have been thinking about second K2 to do this. Any experience? How to mute receiving K2 when transmitting other? That would also permit Single Op Two Radio SO2R operation in contests. 73 Jukka OH4MFA K2/100 #4293 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Hi Guys
Been there, done that... My "boat anchor external receiver" project will do that... Even with a receiver that's not a boat anchor. As I tap into the K2's receiver after the low pass TX filter (on J13), listening on other bands than the K2 is tuned to, is a bit variable and non existent in some cases. The cost is very low, it's an easy weekend project and doesn't involve any modifications to the K2 other than fitting a socket at J13. Options for opto-isolator or relay switching. http://www.astromag.co.uk/k2/K2externalRX.pdf 73 Dave, G4AON >Ability to hear DX and pileup simultaneously.

Haven't built it up yet, but I bought it exactly with this in mind - something small but adequately powerful to take with my KX-1. Unfortunately, 35W is enough that the tuner becomes an issue: that's more than the T1 is rated, and most everything else jumps to 100W capacity and becomes much larger. Maybe the Z11? 73 de chris K6DBG _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list. Subscriber Info (Addr.
