Another point to consider is you can buy two of the cheap Chinese HTs for about

what the diplexer

in the Arrow costs. That's the cheapest way to get to full

Sure, now you tell me that after I buy the Arrow with the diplexer! =^D  But seriously, I bought a used Arrow that already had the diplexer, however I have done just as you suggested... I bought a second Baofeng and a couple of BNC jumper cables. Now I have to sort out splitting to headphones and my recorder both.
