[HCDX] Kenwood R-1000

[mwdxer@xxxxxxxxx (Patrick Martin)]

I recently bought a Kenwood R-1000 for a back up receiver. I mainly use
the Drake R-8, but I needed a backup with a noise blanker as I live near
an electric fence. The noise blanker in the R-1000 works nearly as well
as the one in the R8. In some cases better. Anyway, I changed a few
things like  change the sellectivity for the 2.7 khz SSB filter would
work on AM (with the e mail help of Don Moman), and cut the cap for of
the AGC circuit so the attack time would be faster. I fould a bit of
attenuation in the AM circuit, but the three resistors are buried on the
main board, so at this time I really didn't care to tear into it. After
discovering the separate MW antenna input was set at 1000 ohms, I
decided to build a matching transformer as all my antennas are 72 ohm
coax. What a difference! The gain jumped up close to 10 DB, bu the S
Meter. It did make a bit of difference though. I do need a presellector
in the circuit. However, the sensitivity is about equal with the Drake
R8. The R 1000 seems to have a decent low noise floor too. Tonight,
playing around with the receiver, I found KVTK-1570-South Dakota with
their 71 watts topping CKMW-MB off the Eastern Beverage, no presellector
at that time. The receiver has been OK with Tahiti-738 and New
Zealand-657/567 also, although the Drake R8 does better in ECSS and the
passband tuning. I may replace the 2.7 khz filter with something better
at a later date. Not a bad receiver for a backup. I can't complain.
