RE: [drakelist] Radio advice?

[Tom Taylor \(MSTV\)]

A TR-4 is better for CW than a TR-3 because of auto-break-in. In other words, when you put a TR-4 in CW mode, you can still hear the receiver. When you key the transmitter, a relay closes and at the end of keying, depending upon delay, the transceiver switches back into receive mode. When you put a TR-3 into CW mode, the transceiver switches to transmit mode and you no longer hear the receiver. In other words, you have to manually switch the TR-3 out of CW between transmissions.   On the other hand, a TR-3 uses three 12JB6’s, which are generally less expensive than the 6JB6’s a TR-4 uses.   Neither a TR-3 nor a TR-4 has any special CW filters or RIT capabilities. Later models of the TR-4C added some of these CW features.   Both the TR-3 and TR-4 work well on SSB.   Tom n7tm   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, November 01, 2005 4:29 PM To: drakelist@zerobeat.net Cc: [EMAIL PROTECTED] Subject: [drakelist] Radio advice?   A good friend of mine (not presently on the LIST) is interested in acquiring his first Drake rig and was interested in either the TR-3 or TR-4. I told him in many cases you can tell the quality of the radio by the lack of complaints and by the lack of mods available. As you can see my information is limited. He would appreciate if those with some insight would contact him directly:   Larry W8GTT Redmond, WA [EMAIL PROTECTED]     Thanks Alan KB7MBI
