The first and most important three things are Location, location, Location
Now if you are, as I am now, A solo RVer.. You can put the radios anywhere handy.. Dining room table, Side board in bedroom, (Back Before Marraige I had a radio attached to the night stand, funny story omitted). anywhere you want.
My RV is a bath and a half model.. I was married when we bought it.. So wife is not a Ham and not interested (I tried, it would have been useful if she had gotten a Tech) so I put the radio in the half bath.. That way I could close the door.. But it is a bit .. er.. crowded there.. (no shower though so the radio is safe)
Location of antenna
location of second radio (I mounted a 2x4. somewhat beveled, on the side wall next to the driver's seat.. IT is bolted firmly to studs, Radios mount on that beam).
I have VHF/UHF/CB/CB in cockpit (19 and 13) and HF VHF/UHF in half bath and a hand held I can put anywhere.
If you have AT LEAST a general class another good spot to put "radios" is on your Smart Phone, Tablet or Computer
Go to or google to www.RemoteHams.com
You can get the RCForb clioent for both Android (Beta 9.95) or PC (Free)
Once you have it installed, and your license uploaded and verified.. Then 9am Eastern on Friday, or 11 am EASTERN on Tuesday
Search in the app for N4GYN.. You may see my call as connected, we can chat while Ray runs the net and monisors (He dual tasks well less I nail him with a zinger just as the other station turns it over to him) You can even join the net using Ray's Radio.. I do that on bad proprogation days of if not at home.
Echo Link, Do Drop Inn is a popular reflector node... I do not know if it is still there as I've not checked in in a while but Mornings (Eastern) like 9 to noon is a good time. Again you must uplaod your license to the folks who run it to be authorized. Since Echolink is mostly VHF/UHF I think a Tech will do here.
