SWR Bridge

For performing measurements on antennas with a spectrum analyzer an swr bridge is a very nice instrument to calculate the SWR of antenna systems.

CNC craftmenship by Theo PA0KN who made a perfect fit enclosure. Decal is laser engraved.

SWR bridge was bought on ebay and fits very good in the enclosure designed and made by PA0KN

10 meter (CB) transceiver.

Many CB transceivers are sold on the market as a 10 meter ham transceiver.
Of course this is done to “fool” the law and give CB operators the chance to buy an all mode transceiver with a large frequency span and more power than legal equipment.
These transceivers are very easy to modify to cover 11 and 10 meter as well.
For amateur use the models without fixed channels are quit usefull, although the lowest tuning frequency is limited to 100 hz.
I was able to buy a very nice Alan 9001 for 50 euro. You can also consider a Uniden / President Lincoln or Anytone models.
Qrv for a budget? Get a used CB radio!
