HT whip antenna
Maybe out of context of this group but I'm looking for some intelligent answers.
Anyone know of a "good" whip for HT use? ?Dual band would be nice, but better yet a triband better. ?I' tried a few models from Diamond, Comet and some "white box" ones from China. However the return loss is poor to unusable in the area of 8 ~ 0 db respectively. I have more results on the web site, but don't wanna bore the readers.?

4 pin power cord and gender changer for sale
I have for sale 2 items for the Kenwood TS480/590? ( and a few other radios).
?
1. 4 pin power cord used in most modern HF radios. 6 feet long, spade type fuses in both lines. Each line consists of 2 cables, for a total of 4 cables. Handled 100 watt radios with no problem.?
?
2.? Several Kenwood radios use a male DB-9 connector for computer control. Many of the USB to serial cables you buy off of ebay or Amazon have a male DB-9 on the one end. So here is your solution! I have a DB-9 female to female gender changer plug. Insert one end into the male connector on your rig, and now you have a female DB-9 connector to plug your cable into. Great for CAT control of your radio.??
This one is 2 to 3 inches long, made out of hard plastic, and built like a tank. It should hold up very well.? I am asking $22 shipped for both. I can take paypal/check/MO/cash/cashapp. 73 John AF5CC |

Kenwood TS-570S SSB, AM Reception problem
Hello group,
Nice forum here, for sure. I have a strange issue with one of my TS-570S transceivers that exhibited low sensitivity when first turned on with SSB LSB/USB and AM. CW reception and transmission is not effected. The SSB and AM is almost perceptible, and once it warms up, it would work fairly well again. Now it's become a permanent problem, with only CW functioning properly. I am thinking a mixer issue, and most likely a leaky capacitor. Just wondering if there is someone on the group here who's had this problem and how to track it down. Thanks! Dave NS8S |

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. |

Re: BT-13
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.

Re: BT-13
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

Re: nxr-1700 DMR set up
The process to connect to Brandmeister should be 'similar' to connecting a XPR8300 or XPR8400 to Brandmeister. You need to get an account for a repeater and the it's repeater ID on Brandmeister. You need to get a "Master Server" assigned to you from the Bandmaster folks You can then connect to the Master Server by it's IP address and your password for the account you setup the same way you would for a XPR8400 The fields in the programing software for 'IP CONNECT' should have synonyms for the same thing.?
