- I am looking for a 2m mobile SSB rig. The only two that I can find are
- the Yaesu FT-290R and the Kenwood TS-751. I have several pieces of
- Yaesu equipment and they are outstanding. I have only one piece of
- Kenwood equipment and have had only one problem with it that took about
- three months to get fixed. Can anyone give me any comments or
- recomendations..... Thanks

-
- I have for sale a Kenwood TM-241A for $310. Buyer pays shipping.
- It is in perfect condition.
-
- This radio is only 2 months off of the shelf, and therefore
- comes with the warranty. It is for sale because I am interested
- in the 732-A.
-
- Please reply through E-mail. Thanks.

- To: ham-equip@ucsd.edu
-
- I've followed various GPS threads as they've come and gone. In order to pose
- volume/price arguments to folks in the business, what would be the size of the
- amateur market for GPS engines?
-
- Presume an engine consists of the entire RX, minus antenna, including a data
- port (probably NMEA 0183), on a PC board. Examples are currently manufacured
- by Rockwell, Magellan, Canadian Marconi, Plessey, and Trimble, among others.
- Marketed in the $500 class for single-unit quantities.

- Although the impedance may be closer to 50 ohms, the SWR will
- INCREASE. Adding reactive impedance to a resistive load
- will NEVER decrease the SWR. Although the total impedance value
- may be closer to 50 ohms, the reactive-ness will just make the SWR worse.
- Stare at a Smith chart, and you will see this.
-
- Intuitively, the only way to decrease the SWR is to increase the
- amount of power that is adsorbed by the load resistance. Adding
- reactance in series with the resistance can only decrease the
- voltage that the resistance sees, and reduce the power it is adsorbing.
