Help: Re-Pin H-250/U Military Handset

[dave6890]

I have a milsurp H-250/u radio handset that has the stock 7 pin connector. I want to re-pin it for either a Kenwood V71A, Icom 2300H or Yaesu Ft-7900R

I have seem some diagrams for re-pinning it for an Icom Ic-7200. I only have a Technicians class license and although I would like to get into HF, I don't even know what my license grants me for HF.

Any help with both re-pinning the handset and HF stuff is appreciated.

Thanks.

I don't like to sound rude, but if you have your Technicians license, I am sure that they told you the bands and modes that you can operate on. I'm sure that a search or the ARRL site will tell you the bands and modes a Tech can be on. In Canada, Basic is 50 mHZ and up. Basic with Honours and Advanced have full HF as well. Advanced gives you permission to set up repeaters and more output power. A quick search would bring this reference up: http://www.arrl.org/frequency-allocations. Sorry, can't help you on the pin

I know the band plans and frequency allocations. I just remember reading http://www.arrl.org/frequency-allocation, that Technicians have limited access to HF bands.
Higher Frequencies:
All modes and licensees (except Novices) are authorized on the following bands [FCC Rules, Part 97.301(a)]:
2300-2310 MHz
2390-2450 MHz
3300-3500 MHz
5650-5925 MHz
10.0-10.5 GHz
24.0-24.25 GHz
47.0-47.2 GHz
76.0-81.0 GHz*
122.25 -123.00 GHz
134-141 GHz
241-250 GHz
All above 300 GHz

I did a little more research and found that it isn't even worth the money if you are a Technician class. New Technician HF Priviledges

In the U.S., Technician class license holders can operate on 75 kHz of the 80m band using CW, 100 kHz of the 40m band using CW, 175 kHz of the 15m band using CW, 300 kHz of the 10m band using CW, RTTY, or data modes using up to 200 watts, and 200 kHz of the 10m band using CW or Phone (but not FM) using up to 200 watts. When the band conditions are good, you can do pretty well on 10m using simple antennas and low power, so don't discount your Technician HF privileges.

Thanks for your input.

I'm teaching myself morse code now and probably will be good enough at it to send short messages in a few months or so. Truth be told, I'm only teaching myself CW because of my grandfather. He was a radio operator in WW2 on B-29s and he taught me some morse code but I'm illiterate with anything other than SOS, Hello and some abbreviations.

My current priorities are getting a dual band mobile and getting familiar with Echolink. Money is not abundant these days so I probably wont buy an HF rig unless it's a good deal. If anything, if I see a decent used HF transceiver at a trade show or something, I'll buy it and just RX until I familiarize myself with it.

On the H-250 handset the U-229 connector pin A is common ground, B handset speaker, C PTT, D mic hi. The wires are too big to fit an RJ-45 type connector used on some radios you mention so its probably easier to make an adapter cable.

You can sometimes find female U-229 series connectors on Ebay then cut a premade RJ-45 cable in half and make the adapter. The H-250 mic element is dynamic and about 150 ohms impedance, it will interface to most modern radios ok.
