Discussion about the Mountain Topper assembled unit by LNR PrecisionJune 1, 2015 at 2:36 pm #981no-na-meParticipant
I have a couple of questions on the MTR manual.
What is high SWR at 5w level? Above 2:1? 1.5:1 ?
There is mention of attenuation in section on RIT; is there attenuation? if so how?
Very happy with the rig so far.

Got the Mountain Topper and the MTR 3 Band EndFed Antenna at the Huntsville Hamfest. Took it to Morton Hill (W4A/VR-001), Calhoun County, Alabama on 2 Sept 2015. Powered the rig with a fresh nine volt battery so it was running about 2.5 watts. Had tuned the Antenna in the backyard the week before in the same sloper configuration with the far end up 15 feet and the near end just 2 feet off the ground. Was able to get 19 contacts, most on 40 meters. Worked 20 and 30 meters for at least 4 contacts each. The QTHs ranged from FL to NJ and out to AZ. I am a CW/SOTA beginner using a leg key. The rig performed excellently, and the SOTA chasers are very generous folks. This was a great purchase, and I am very happy with the radio and antenna combination.

I purchased one of the first 100 MTR that LNR was selling, and I have to say just how thrilled I am with the radio. I recently sold my Alinco SR8T, so for a while, the MTR is and will be my “main rig” in the shack. (Antenna is LNR EF-10/20/40)
Last night, I did something that I had never been able to do with OTHER radios in the past: I was able to hear the NCDXF beacons on 14.100 MHz. The RX on the Mountain Topper is so good that it was quite easy…my FT-817ND couldn’t do it, nor could the SR8T. Also, last night on 30m, S57V was calling CQ and with 5w I was able to get him with ONE CALL.
Outstanding job!!!November 5, 2015 at 8:41 pm #1282KE0FIDParticipant
Just recieved my Mountain Topper and just want to know what size and type of plug fits in the antenna jack ?? The documentation makes no reference as far as I can see.
Thanks.November 26, 2015 at 4:43 pm #1407ve3vxoParticipant
I read on the AT sprint forum that the MTR has a problem with locking up in freezing temperatures. Is this being looked into? I sent a message to your support email address asking that my order not be shipped until this issue (which seems to be a firmware problem) is fixed and the updated firmware is flashed to the rig. I got no response from support.

I don’t know if this has been asked here or not……
Is the MTR 5 band going to be offered here complete and ready to go like the 3 band model is now ?? Thanks…EdNovember 30, 2015 at 6:02 pm #1410kb2sdrParticipant
I believe Steve made mention of turning it over to LNR in one of the Yahoogroup posts. I will glad when he does, I have been collecting the radios. I always seem to miss the production runs because I don’t frequent the groups everyday.

My gynecologist advisable me Estrace, when heard, complains of bad feelings.
The truth is, Vermox has a broad spectrum of action and can apply the treatment of diverse types of helminths, however, it is vital to make a required evaluation of feces and blood to identify the precise type of worms and to select an acceptable scheme of remedy.Zovirax OnlineOctober 25, 2016 at 11:16 pm #3192KG5ARDMember
I set up my MTR 3 next to my Icom 718 with the end fed antenna on the MTR and my Buddies Pole on the Icom. I could hear signals on the MTR that were below the noise level on the Icom, which has a Collins crystal filter installed. I am still learning CW so I plan on wearing this radio out. I am thinking of using for Field Day next year. Extra points: QRP, Battery, portable, etc.
