BT-13

K7SRG All Messages By This Member #396 I'm looking for the Kenwood BT-13 pack. It's for running the TH-F6A radio with four AA cells as a battery. -- - Regards, Karl Shoemaker To contact me, please visit SRG's web site at? for the current email address.
Samuel W7STF All Messages By This Member #397 I don't claim to know your usage / want scenario. Seems like the pack you are asking about may be discontinued. You could write Kenwood in the US and UK and ask if any authorized dealers here or in the UK have what you are looking for. ? Is the issue air travel with Li-ION battery packs? Camping? Hiking? ? FWIW: Batteries America sells a 4000mAh cell, the PB-42XL. ? They also sell an "eliminator" which can be used with 12-24V supply and might provide flexibility depending on what you are trying to accomplish. (Use in the car or off the car battery)? ? And as we know, there are many TH-F6A aftermarket batteries on ebay.? ? I know little about this, but thinking out loud, I would imagine one of the options above would be superior to 4x AA cells in an enclosure because the voltage would be higher, as well as the current rating of the supply. I'm also thinking the discharge curve of one of these replacements would be superior to that of an alkaline cell arrangement.? ? Your other option would be to roll-your-own ?
K7SRG All Messages By This Member #398 Thanks, Samuel for the input. ?I have a very large repeater (coverage) in Washington State. You might wanna check the site out, link below. I'm a retired professional in the tel-com industry with the State of Washington. Most of my career was working on analog and digital microwave systems, LMR, telephone, radar and several other areas working with other US agencies.? ? For my hobby I have about 20 sites for SRG's coverage. Presently, when I visit the sites for repairs, PM or routine tasks I take my three HT's for working with the equipment. The three HT's are the Icom 2AT, 3AT and 4AT as my system uses both the VHF bands and the one UHF band. ? I used to use Ni-Cad packs by Icom, then switched to the BP4 type a love them. I don't have to carry around a charger, checking if I did charge up the HT's bla, bla and can just pack and go to the sites. ? I purchase the copper top cells in bulk from Cosco. I have several other devices that use AA cells which keeps my inventory simple.? ? I've also "rolled my own" on these HT's, building battery substitution packs. In fact, I have a rack mount fixture to hold five of these HT's for monitoring system on various bands. They are powered off the station's battery. ?However, these HT's are out of the 1980's so, obviously very old (40 years) ?and starting to fail.? ? I went shopping for a tri-band HT and the only types I found was from Kenwood and Yaesu. I found the latter very expensive. Recently, I came a across a used but in great condition on the latter, thanks to a friend of mine finding it on line. Therefore, I ended up purchasing the Kenwood model of TH-6FA. ?I've read the manual (several times) and have starting using it. However, I failed to do my "homework" on accessories available for this unit. ? ? So, after the purchase I started to realize I may be stuck with the (included) Li-ion (spell?) battery. After reading about the risks of fire on this type of battery I really want to stay with alkaline types. The BT-13 shell holds four AA cells for the unit's battery. Even though the radio operates at low transmit power levels this way, that's not important for me since most of my usage is at the remote sites. I also have test equipment for radio maintenance and sweeping the lines and antennas. ?I'm a documentation extreme for today's amateur standards. ? I'll keep my hopes up in finding at least one BT-13. -- - Regards, Karl Shoemaker To contact me, please visit SRG's web site at? for the current email address.

When you indicated you had "rolled your own", I figured you answered your own question. I cannot see how swapping batteries is more convenient, but I cannot speak for how you view the situation obviously. I just know my truck has both a cigarette lighter AND a DC to AC inverter, and there are several ways to keep the TH-F6A topped off in most all vehicles. ? I think that perhaps you could write the people at DX Engineering and ask what happened to them, or KENWOOD/JVC USA and UK, and raise the question. Couldn't hurt.
K7SRG All Messages By This Member #401 They were'nt helpful.? On the Icom HT I change out the AA cells about once a month - very nice? for me :) I've ordered a second LOon battery from Walmart to keep me out of the woods. -- - Regards, Karl Shoemaker To contact me, please visit SRG's web site at? for the current email address.
