Considering purchasing an icom. Can anyone comment on using the 51A vs a baofeng? Particularly how sensitivity compares.
Thanks and 73 KD9CFO
Hi Oliver,
An optimal choice would be a full-duplex HT, one that can receive on one band and transmit on another at the same time. The 51A won't do that.

And specific to the 51A: http://forums.qrz.com/index.php?threads/icom-id-51a.441780/
The Kenwood TH-D72A supports full duplex (also called cross-band repeat), for example.
From work-sat.com: "Although it is preferable to work the FM sats in
full-duplex mode (where you can hear the downlink as you key your mic), only one currently-manufactured HT does that well in our VHF/UHF mode - the Kenwood TH-D72a. "

Or, he can use the ID51A to receive and the Baofeng to transmit. He can use an Arrow with the diplexer or buy a Comet one.
Cheaper solution than the Kenwood HT.

You can also use two cable runs from the Arrow to the radios -- one for UHF, the other for VHF; no diplexer needed then.
That's what I do.

Hi,
I don't recommend the Baofengs for TX side in 2m, many of them has a notable spectral "impurity" with very strong 3rd harmonic on 70cm, see this:

I already own a set of baofengs and an arrow antenna . I split the rx/tx.
Should I be utilizing a duplexer on the receive regardless of this fact?
Thank you to all who have commented so far. You have presented additional things to consider that I would not have known otherwise. On Jan 21, 2016 6:00 PM, "Fernando Ramirez" framirezferrer@gmail.com wrote:

Hi Oliver.
This problem with the baofeng affect us only on the case you have a 2m uplink; if you have the case you may want to put a duplexer (or a LPF for 290Mhz) on the TRANSMIT radio in the side of 2m as close to the radio as possible, this will considerably attenuate the 3rd harmonic on 70cm.
