Single antenna goes to a change over relay that is comtroled by the transmitter. It switches the antenna between the tx and the rx. The matching receiver is the HR-10. I habe a DX-60b witb the VFO and HR-10 receiver. This isn't for someone that has no idea about separate tx/rx BTW. It is not something you would really run on 11m either. It covers 10 thru 80 m. Like I said before, it depends on what you want to do with it. 80m AM great. 11m playground forget it.
BTW Heathkits are only as good as the guy that built it.
You must use xtals that are "Fundemental"...meaning the xtal must be cut for that specific freq.... xtal's that were cut for like the old Johnson and other xtal rigs of that era...most were cut with an "Offset" built in...meaning channel X? is not really cut for that freq....it's cut for that channel +/- the TX/RX "IF" freq...
All the Best

Hah?
Something like a Telsat SSB 100 channel mixing.
BJ that depends on the band IIRC. An 80m xtal will also work on 40m. As for 11m operation I did put mine there once or twice just to piss a few people off that were splattering all over. I modded the VFO to drive it down to 11m. You have to be VERY careful with the audio drive. The single 6146B final is grid modulated and there is way more drive available than is needed. It will overmodulate and splatter easily and burn up twh tube easily doing that too. I succeeded in doing what I wanted to do and removed the VFO mod as it affected all the bands and the dial meant nothing.
BTW the receiver used witb it needs to have a remote mute finction to switch off when you transmit. You don't just turn the volume down.
.... and there ain't nothing wrong with the direction it's going either...
