Lscott Posted March 31, 2021 Report Share Posted March 31, 2021 One of the first things I do when interested in a model of radio I’m not familiar with is look for any manufacturers brochures. That gives a quick run down on the features. If no luck then look for the user manual, service manuals etc. https://www.ameradio.com/doc/Kenwood_TK-7180_TK-8180.pdf http://www.repeater-builder.com/kenwood/pdfs/tkr-740-840-brochure.pdf Quote Link to comment Share on other sites More sharing options...
Lscott Posted March 31, 2021 Report Share Posted March 31, 2021 Oops. The one link is for the repeater. Editing and copy paste isn’t the best on a smart phone when you’re tired. But you get the idea. Quote Link to comment Share on other sites More sharing options...

axorlov Posted March 31, 2021 Report Share Posted March 31, 2021 840 vs 880 vs 8180: also consider software. I understand that software for 840 is DOS, while 880 and 8180 is served by Windows applications. If you are not afraid of dealing with DOS, then fine. 8180 also has a removable head, allowing better installation in tight spaces.

jgillaspy Posted April 6, 2021 Report Share Posted April 6, 2021 Hey folks, sorry it has taken so long to get back to you. I think I've got the pieces I need together on ebay now. Going to be around $150 for radio, keypad mic, mount kit, programming cable, software and power cable. I already have a mag-mount antenna and cable. I'll look around here for a programming guide. My understanding is that I can't Tx on the low-power channels with this unit. Is that correct? I have found the Service Manual and Instruction Manual, but no Tech Specs.

Lscott Posted April 6, 2021 Report Share Posted April 6, 2021 If you're looking for the TK-880H brochure with the basic radio spec's look here. https://www.ameradio.com/doc/Kenwood_TK-780%28H%29.pdf Quote Link to comment Share on other sites More sharing options...
Lscott Posted April 6, 2021 Report Share Posted April 6, 2021 The FCC certification grant is located here for the TK-880. https://apps.fcc.gov/oetcf/eas/reports/Eas731GrantForm.cfm?mode=COPY&RequestTimeout=500&application_id=9wLBCa2uBguLpUibGdVsCA%3D%3D&fcc_id=ALH24593210 Quote Link to comment Share on other sites More sharing options...
jgillaspy Posted April 6, 2021 Report Share Posted April 6, 2021 Thanks! Neither of those address the low power output, but I found elsewhere on this site that channels 9-15 (I think) are not useable for this device since it can't go that low on power. So channels 1-8 and the repeater channels. That should be just fine. I also found a TK-880H on Used-Radios.com with Mic, Mount and Power cable for $110 - better than ebay. This Thursday it is mine. . . I'm still ordering the recommended cable from ebay. JG Quote Link to comment Share on other sites More sharing options...

The narrow bandwidth and low power FRS channels are 8 to 14 at 0.5 watts. Channels 1 to 7 are 5 watts max and wideband, while the repeater main channels 15 to 22 are wideband and 50 watts max. I just added another Kenwood TK-3170 and my first TK-3180 to my HT “collection”. I spend to much time on eBay and can’t pass up a good deal. 8-/ The programming software for the TK-3180 complained about several features that may not work right because the firmware was too old. After contacting Kenwood support they were nice enough to supply me with the most recent version. Didn’t even fuss about it. I might have to buy yet again another different programming cable myself. I have a buddy who got his hands on a used Kenwood NX-820HG-K2 and mic from his work place they were going to dump. He has no interest in digital radios, it also does analog, so he said I could have it if I wanted. Now I need the cable. It’s not part 95 certified however. https://comms.kenwood.com/common/pdf/download/10_NX-720HG&820HGBrochure.pdf Quote Link to comment Share on other sites More sharing options...
Extreme Posted April 7, 2021 Report Share Posted April 7, 2021 I buy from UR all the time. They can/will program 16 channels for you allowing you to skip the 8 - 15 and have them insert the repeater channels instead for your 16 total. You still might have to program some but if you have the repeater tones they'll put them in as well as key assignments. Thanks!

jgillaspy Posted April 9, 2021 Report Share Posted April 9, 2021 So, everything is ordered. Hope to see it early next week. I did have UR program in those 15 channels, so I should be able to get started quickly. At this point I'm not seeing any real GMRS traffic in my area and the closest repeater is just out of range. Unfortunately I have an HOA, so no repeater tower for me although I do have space in my 1/2 rack my computer lab is in. . . JG Quote Link to comment Share on other sites More sharing options...
jgillaspy Posted April 14, 2021 Report Share Posted April 14, 2021 So, radio kit arrived today and I have to say they do great work. Power on message is my last name, channels programmed as requested. The radio looks new. I'll have to wait until the weekend to route the wiring, but I bench tested it today and programmed a few more channels in Group 2 (ham 70cm repeaters near me). The cable from bluemax49ers worked like a champ. I even reprogrammed the buttons as suggested previously. You folks ROCK! Can you adjust the VCO on this v1 radio? I get an out-of-bounds message when programming in the 70CM band and didn't hear any traffic from the repeaters. Not going to key up until I pass my Tech test.

Extreme Posted April 14, 2021 Report Share Posted April 14, 2021 I programmed area Ham repeaters into my 880, got the out of bounds message but hit ok and proceeded. I'm in listen only mode but did eavesdrop on a Boise area ham conversation last hunting season so it worked. Couldn't have talked back if I'd wanted to since my TX was fried at the time. Just programmed ham into my new 880 for the SxS and same notification. Quote Link to comment Share on other sites More sharing options...
jgillaspy Posted April 14, 2021 Report Share Posted April 14, 2021 GMRS traffic is almost nonexistent in my area of San Antonio. 2 of the 4 repeaters aren't online and one (Downtown) hasn't responded to my access request. Getting a bit frustrated, but the good news is the air waves are mine!! Once I get the mobile installed I'll start working w/my wife on distance.

axorlov Posted April 14, 2021 Report Share Posted April 14, 2021 Congrats! I'm not sure about 880 V1, but V2 tunes into the repeater part of Ham band without problem (only warning pop-up in the software). In the place where I live, San Francisco Bay Area, 70cm repeaters are quiet, except the ones that are placed lower in the mountains and linked to 2m repeaters. There is a reason for that, the PAVE PAWS missile defense site site north of Sacramento, that forced prominent high-placed 70cm repeaters to go off-air. On opposite, Los Angeles area has a huge number of 70cm repeaters on air. Quietness of the ether may not be an indication that there is something wrong with the radio.

jgillaspy Posted April 14, 2021 Report Share Posted April 14, 2021 So, I used the repeaterbook app and put in anything w/in 15 miles of me for 70cm. I may have the Tx/Rx freqs backwards. Anyway, I'll keep trying. JG Quote Link to comment Share on other sites More sharing options...
jgillaspy Posted April 27, 2021 Report Share Posted April 27, 2021 So, I finally got all the tools to test out my TK-880H. Here is what I got.First up, GMRS01: Second, a local repeater: So, I'm over powered for GMRS01-07 and under powered for repeaters. Why is my power so low for the repeater? I have it set to High in the software. I'm using a Nagoya dual-band VHF/UHF antenna I got from Amazon. JG Quote Link to comment Share on other sites More sharing options...
WRVU874 Posted April 2, 2023 Report Share Posted April 2, 2023 I Bought a few used TK880s, I could use a little help: 1. Does anyone know why C152, the 1000uF would be removed? 2. The I/O (Power switch) has been set up to turn on and off the audio amplifier (I believe this is a power saving move for use a porta-peater). Any information on returning the I/O switch function to power On/Off would be appreciated. Frank Quote Link to comment Share on other sites More sharing options...

Frank I suspect C152 was removed because it failed at some point, likely shorted, blowing the in-line power fuse. Running off a regulated supply it might not matter so whoever did it just didn't bother to replace it. Just a guess here. I haven't screwed around with the programming software but the power switch thing might be a programmable option to keep the radio on whenever the vehicle is running, turns off when the vehicle is off thus nothing for the operator to forget, like turning off the radio thus draining the battery. tk-880h-svc-man.pdf Quote Link to comment Share on other sites More sharing options...
